Choosing the right bike tyre

How to choose a bike tyre?

To choose a bike tyre, first identify the size of your current tyre. Then, select a tyre suited to your usage, whether for road cycling (racing, training, cyclocross, gravel), city (commuting, touring, trekking), or mountain biking (cross-country, trail, enduro). For more detailed information, read our article on how to choose a bike tyre.

What bike tyre size fit my rims?

To determine what bike tyre size fit your rims, check the size marked on the tyre sidewall. For bikes less than 5 years old, you can often find specifications online using the bike's reference number. Alternatively, consult your dealer or the bike's technical data sheet. Ensure the tyre dimensions match the specified range to maintain safety and handling.
For more information, read our article on how to choose a bike tyre.

What are the best touring bike tyres?

Our touring bike tyres are crafted for cyclists who enjoy exploring paths less travelled. If this sounds like you, you may want to consider the MICHELIN Touring Range, depending on the ratio of paths you use. These tyres generally have a little more tread, allowing better control and grip when venturing slightly off-road.
For more information, read our article on how to choose a bike tyre.

What is the best downhill mountain bike tyre?

Our Downhill ranges are available in two levels: Racing line and Performance line. The Racing Line is specifically designed for people looking for maximum performance in terms of grip and solidity. The Performance Line is designed to give you a good performance compromise for more moderate Downhill use.
For more information, read our article on how to choose a bike tyre.

Where can you find your bike tyre size?

Finding your bike tyre size is quite easy since it is generally displayed on the tyre sidewall. We explain everything about bike tyre sizes in our dedicated article.

How to understand bike tyre sizes?

The size of your bicycle tyre will probably be indicated in one of three ways: ETRTO measurement (for example: 23-622), imperial measurement (for example: 29 x 2.10) or metric measurement (for example: 700 x 23C). We explain each of these in detail in our article on bike tyre sizes.

Bike tyre pressure

What is the correct bike tyre pressure?

It would be too simple and incorrect to claim that there is a fixed pressure suited to all bicycle types, riders and situations. MICHELIN provides a range of recommended bike tyre pressures for all tyre models. 

What is the correct mountain bike tyre pressure?

The recommended MTB tyre pressure can be found on our recommended pressure page. Note that there are also some specific criteria to consider, such as the weight of the rider and the fact that on mountain bikes your front wheel should always be set at a slightly lower bike tyre pressure. More info on bike tyre pressure.

What is the correct road bike tyre pressure?

The correct road bike tyre pressure depends on several factors, including your usage, the terrain you ride on, and the weather conditions. It's important to ensure your tyres are inflated within the recommended range to optimise performance and safety. For more detailed guidance, read our article on bike tyre pressure.

How to pump up a bike tyre?

Check the recommended pressure by checking on the tyre & rim sidewalls, remove the cap of your valve, ensure your bike pump has the correct attachment nozzle for the type of valve fitted, connect your bicycle pump to the valve, make a good airtight connection with the pump clamped firmly to the valve and begin pumping. Detailed instructions here.

What are the different bike tyre valve types?

There are four bike tyre valve types: the Presta valve, the Standard valve (also called Schrader valve), Woods valve (also called Dunlop valve) and the Regina valve (also called Italian valve). We explain the particularities of each of these valves in detail in our dedicated article.

What is a Presta valve?

A Presta valve is a type of valve commonly found on bicycle inner tubes and tubeless systems. It is narrower than a Schrader valve, with a threaded exterior and a small locking nut at the top. Presta valves are known for their ability to hold high pressures and are often preferred in cycling. To find out more, read our article on the different types of bike tyre valves.

What is a Schrader valve?

A Schrader valve is a type of valve commonly used on bicycle inner tubes, as well as on car and motorcycle tyres. It has a wider diameter than a Presta valve and is typically equipped with a spring-loaded core that controls the airflow. Schrader valves are known for their robustness and ease of use, often requiring a larger pump head for inflation compared to Presta valves.
To find out more, read our article on the different types of bike tyre valves.

What is a Dunlop valve?

A Dunlop valve, also known as a Woods valve, has a similar appearance to a Presta valve but does not have a threaded exterior or a locking nut. Instead, it uses a simple rubber tube inside the valve to control airflow and maintain pressure. To find out more, read our article on the different types of bike tyre valves.

Changing bike tyres & inner tubes

How to change a bike inner tube?

To change a bike inner tube, you will need a bike pump, at least two tyre levers, gloves, pliers, and a replacement bicycle inner tube (and tyre if needed). Then, follow the detailed instructions provided in our article.

How to change a bike tyre?

The process depends on whether you have a tubeless-ready or a tube-type tyre. Both types require specific tools to complete the task. For detailed instructions on how to change each type of tyre, please read our dedicated article.

How to change a tubeless bike tyre?

To change a tubeless-ready tyre, you need to follow 3 steps: 1/ remove the tyre, 2/ fit the new tyre, 3/ inject the tyre sealant. We provide a detailed explanation of these steps in our article "How to change a bike tyre?".

How to remove a bike tyre?

Depending on whether it's a tubeless-ready or tube-type tyre, the procedure for removing the tyre is different. Please follow the detailed instructions in our article "How to change a bike tyre?".

How to change a bike inner tube?

Follow these 5 steps:
1. Check the rim for damage and replace if necessary.
2. Inspect the rim band and replace if cracked, aligning valve and rim holes.
3. Insert the first tyre bead into the rim.
4. Slightly inflate the inner tube, insert it into the tyre starting at the valve, and use talc for latex tubes.
5. Fit the second bead, starting opposite the valve and finishing at the valve.
For detailed instructions, read our article on inner tubes.

How to use bike tyre sealant?

Check the expiry date of the sealant, remove the wheel, shake the bottle, unscrew the top part of the valve, inject the sealant, screw the top part of the valve back on and shake the wheel. Do not inflate the tyre to its maximum pressure. Simply inflate it to rolling pressure and shake it well after injection. See our detailed instructions in our dedicated article.

How long does tyre sealant last?

Sealant loses its effectiveness once it has been in contact with the air, particularly after several uses. Using an out-of-date tyre sealant or one that has been used several times is likely to give you a poor experience. More information in our article on tyre sealant.

Mountain Bike

How to choose mtb tyres?

To choose MTB tyres, start by ensuring you select the correct tyre size for your bike. Then, choose a tyre that matches your specific riding style and terrain, such as cross-country, trail, or enduro. Each type offers different tread patterns and durability suited to various conditions and riding demands.
For more detailed information, read our article on how to choose an MTB bike tyre.

What are the best mountain bike tyres?

Identifying the best MTB tyres for your use should be fairly simple as all the MICHELIN mountain bike tyres ranges are logically named according to their discipline. For example: Force XC is for Cross Country, Force AM or Wild AM for All Mountain, Wild ENDURO for Enduro, DH for DownHill…
For more information, read our article on how to choose a mountain bike tyre.

Can I change my mountain bike tyres for road tyres?

Using road tyres for mountain biking is not recommended. Simply because slick treads and compound of road tyres are not designed for off-road uses. Road and city tyres are only compatible with asphalt or gravel paths.
For more information, read our article on how to choose a mountain bike tyre.

Can I fit wider tyres on my bike?

Fitting wider tyres on a mountain bike is possible if the frame allows enough clearance. The maximum tyre widths are set by the bicycle manufacturer. It is usually not difficult to fit wider mountain bike tyres to a mountain bike wheel, provided you buy the right diameter.
For more information, read our article on how to choose a mountain bike tyre.

How to prepare an mtb ride?

A good ride is above all a safe ride! And with that in mind, the right bike equipment is the first essential point for your safety. For all-mountain, ensure you have a helmet, gloves, glasses and some proper knee protection. Remember to bring your bike pump in case you need to adjust your tyre pressure. If your bike is fitted with tubeless tyres, remember to check that your tyre sealant is in good working order and isn’t leaking or dried out.

Road Bike

How to choose a road bike tyre?

The choice of a road bike tyre depends on the main use you will make of it. If you mainly ride on roads, select tyres tailored for road cycling. However, if you occasionally venture off-road onto gravel or cyclocross trails, opt for tyres that offer versatility for both terrains.
For more information, read our article on how to choose a road tyre.

Can I put road tyres on a cyclocross bike?

Yes, you can put road tyres on a cyclocross bike. However, while road tyres can be used for road riding, they are not ideal for cyclocross itself. Cyclocross tyres are designed for competition and require a specific bike. They are quite thin and equipped with knobs. For dry terrain, opt for the MICHELIN Jet tyre. For muddy terrain, the MICHELIN Mud tyre is recommended. For more information, check out this article.

What is a gravel bike?

A gravel bike is a multi-purpose bike designed for riding on a variety of terrain, including gravel roads, dirt tracks and pavement. The frame and fork are robust and have greater clearance for the tyres. They are often fitted with extra racks and mudguards, making them suitable for touring and adventure cycling. More info on gravel tyres.

Can you put road tyres on a gravel bike?

Yes, you can put road tyres on a gravel bike. If you ride both on the road and off-road, gravel tyres are a suitable choice. They are designed for enhanced comfort and better resistance to pinch-shock. Wider tyres can be run at lower pressures, reducing the risk of punctures. However, it's important to pay attention to the wheel width and compatibility (see our bike tyre size chart).
For more information, check out this article.

Can I put gravel tyres on a road bike?

Yes, you can put gravel tyres on a road bike, but certain precautions should be taken. It is generally not recommended to fit gravel tyres on a road bike. Gravel tyres are designed for rougher terrains than those typically encountered by most road bikes. Road bikes are less versatile and too rigid for gravel tyres, making them less ideal for this purpose. Additionally, it's important to pay attention to the tyre width and compatibility, as not all dimensions are compatible with road bikes.
For more information, read our article on fitting gravel tyres to road bikes.

What are the best gravel bike tyres?

If you ride on roads and paths with roots and stones, opt for our MICHELIN Power Gravel range (off-road / road use = 50/50). If you mainly ride on the road and occasionally use towpaths or forest tracks, choose our MICHELIN Power Adventure range (off-road / road use = 80/20). For more information, read our article on how to choose gravel tyres.

Cyclocross 

What are cyclocross tyres?

Cyclocross tyres are designed for off-road racing on a variety of terrain including grass, mud, and gravel. They have a tread optimised for traction and mud evacuation. They are narrower than mountain bike tyres but wider than road bike tyres. More info on cyclocross tyres.

How to choose cyclocross tyres?

Cyclocross tyres are specifically designed for competition and require a dedicated cyclocross bike. These tyres are thin and equipped with knobs to provide better traction. For dry terrain, opt for the MICHELIN Jet tyre. For muddy conditions, the MICHELIN Mud tyre is recommended. It's important to note that when participating in cyclocross, the maximum tyre width allowed is 33mm. For more information, read our article on how to choose cyclocross tyres.

What is TPI in tyres?

TPI stands for "Threads Per Inch". This means the number of threads in the casing of the tyre’s carcass ply for one inch. The higher the TPI number, the higher the density of threads, and the thinner each thread will be. Each bicycle tyre is tailored to match its intended usage, so the TPI can vary depending on the range and application. You will also need to make sure to use the correct pressure depending on the tyre you will select, and your riding conditions. For more information, read our article on TPI and tyre pressure.

Tubeless, Tubeless-Ready, and Tubular tyres

What are tubeless-ready bike tyres? 

Tubeless-ready bike tyres do not require an inner tube to maintain air pressure. Instead, they use the bead edges of the tyre that securely connect with the rim's lips to form an airtight seal. This distinguishes them from traditional tyres, which rely on inner tubes for pressure retention and puncture repairs. It's important to note that tubeless-ready tyres can be used with or without an inner tube. If used without an inner tube, sealant must be added to ensure the airtight seal. 
For more information, read our article on tubeless tyres

How to fit tubeless tyres? 

To fit a tubeless tyre, you'll need a tubeless or tubeless-ready rim, a Presta valve, two tyre levers, a pump or compressor and latex sealant. We've provided a step-by-step process in this article

How to fit a tubular tyre? 

A tubular tyre cannot be fitted to just any bicycle wheel, so make sure your wheel is compatible. Depending on the gluing option you choose, you should equip yourself with: specific glue or adhesive for tubular tyres, a brush to apply the glue, a pair of gloves. Then follow our detailed instructions

How to glue a tubular tyre? 

Inflate your tubular to about 1.5 bars to make it easier to apply the glue. Working on a clean work surface, apply a thin line of glue to the underside of the tubular. Spread the glue evenly using a brush. Perform the same operation on the rim. Let the glue dry for about 20 minutes, then position the tubular. More info on how to fit tubular tyres

Durability

How long do bike tyres last? 

The lifespan of bike tyres depends on wear and age. Wear varies based on use, while aging depends on storage and use conditions. Generally, tyres can last up to 10 years from manufacture. After the first year of use, it's advisable to have your tyres inspected by a professional to ensure they remain in good condition. 
For more information, read our article on how long bike tyres last

When to replace bike tyres? 

Replacing bike tyres depends on both wear and age. Wear is the primary factor, with the rear tyre typically wearing out faster. For mountain biking, trekking, and gravel tyres, worn studs indicate decreased performance in grip, traction, and braking. For road and city tyres, signs of wear include a flattened tread and visible underlying plies. Additionally, age is a consideration, with tyres generally needing replacement after significant time or improper storage. 
For more information, read our article on how long bike tyres last

What causes bike tyre wear? 

Bike tyre wear can be attributed to various factors: driving style, experience, track knowledge, incorrect tyre pressure, the terrain, weather conditions. 
For more information, read our article on how long bike tyres last

How to clean bike tyres? 

When cleaning your bike tyres, it's important to avoid certain practices to prevent damage. Avoid using high-pressure washers directly on the tyres, as this can cause harm. Additionally, refrain from using solvents or cleaning products on the tyres. If cleaning products do come into contact with the tyres, be sure to rinse them thoroughly with clean water to remove any residue. 
For more information, read our article on how long bike tyres last

How to improve bike performance? 

To improve bike performance, one of the easiest upgrades is to tailor your tyre choice to your specific use (Road, Cross Country, All Mountain, Enduro, Downhill…) Selecting the right tyres for your use and performance expectations is the best way to optimise your rides. 
For more information, read our article on how to maximise your performance

How to store tyres? 

For good preservation, bicycle tyres should be stored in a dry place, away from UV rays, at a moderate temperature (between 10 to 25°C). We also recommend that you never store bike tyres in spaces where electrical equipment, solvents, hydrocarbons, fuels or chemical products are present. Read our special recommendations for tubeless or tubetype tyres in our dedicated article

How to break in new tyres? 

You don't need to inflate the tyre to its maximum pressure; just set it to the recommended level. The tyre will take its final shape after 24 hours. For your first ride, choose a flat, dry road and perform a few short braking manoeuvres to help the tyre settle in. Avoid braking too hard initially, as this could affect the tyre's performance later on. For more detailed information, read our article on how to break in new tyres

What is the tyre break-in period? 

To ensure optimum tyre performance, a break-in period of 50 km or until signs of homogenisation appear on the tread and sidewalls is recommended. For more information, read our article on how to break in new tyres

Suspension travel

What is suspension travel? 

Suspension travel refers to the ability of the front and/or rear wheel to move vertically to absorb shocks and overcome obstacles. For example, if your bike has 100 millimetres of travel at the front, this means that your front wheel can move vertically by 100 millimetres to overcome an obstacle. 
For more information, read our article on how to choose a bike tyre

How much suspension travel do I need? 

Mountain bike disciplines are categorised by suspension travel. Travel under 120mm is typical for cross-country bikes, designed for speed on smooth terrain. Travel from 120mm to 140mm suits Trail, All Mountain, and Down Country bikes, balancing crossing capacity and climbing efficiency. Travel from 150mm to 160mm is found in Trail or All Mountain bikes for rough terrain and steep descents. Travel over 160mm up to 180mm is for Enduro bikes, ideal for technical descents and challenging mountain courses. Travel over 190mm is for Downhill bikes. 
For more information, read our article on how to choose a bike tyre

Bike Punctures

What are puncture-resistant bike tyres? 

Puncture-resistant bike tyres reduce the risk of flats in various riding conditions. They have a protective layer against sharp objects and are available in different models for specific uses. For road use, choose MICHELIN Power Protection TLR. For urban riding, opt for MICHELIN City Street. For downhill, MICHELIN DH22 is ideal.

To find out more, read our detailed article

How to repair a bike puncture? 

The first thing to check is whether your bicycle tyre puncture is repairable. If your tyre has suffered a small puncture, you should be able to repair it with a bicycle puncture repair kit. First, you need to locate the puncture site and then proceed with the repair. To find out how, read our step-by-step guide

How to find a puncture in a bike tyre? 

Start with a simple visual inspection. If you can't find an obvious cause for the puncture, remove the wheel. Then smear the walls of the tyre with soap (like the kind you use to wash dishes). Air bubbles indicate where air is escaping. Read the full article on how to fix a tyre puncture

How to use a puncture repair kit? 

The specific instructions for your bike's puncture repair kit must be written on the kit. For our MICHELIN repair kit, you need to follow the following process: carefully clean the puncture area with emery cloth, make sure the cleaned area is larger than the patch to ensure good adhesion, peel off the protective film from the patch, apply the patch by pressing firmly over the entire surface, then wait 2 or 3 minutes. The perforation is now repaired. More info on tyre punctures

Bike Handling

Why does my wheel wobble? 

Wobble manifests itself as left-right shakes. If you feel that your back bike wheel wobbles (or even your front wheel), there's usually a problem with the wheel. It's recommended that you get your wheel inspected by a bicycle mechanic. More info about wheel wobble in our article

Why does my wheel hop? 

When your wheel hops you'll feel a vertical bump, as if the wheel was rising and falling with each rotation. This event, which is rarer than the back bike wheel wobble, is just as unpleasant and is enough to spoil your enjoyment of the ride. Therefore, you will need to get your wheel inspected by a bicycle mechanic. More info about wheel hop in our article. 

Rolling Resistance

What is bike tyre rolling resistance? 

Rolling resistance is the friction generated by the tyre's contact with the ground, impacting cycling difficulty along with air resistance and gravity. Although thinner tyres were traditionally used for lower air resistance, modern road bikes often use 25mm or 28mm tyres. These offer better rolling resistance, handling, and comfort, making tyre width and inflation pressure crucial for optimal performance. 

For more information, read our article on how to maximise your performance

What is bicycle rolling resistance? 

In simple terms, bicycle rolling resistance is what prevents you from riding fast. The higher the rolling resistance, the more energy you need to expend while pedalling to overcome it. There are several factors that produce this: gravity, mass, aerodynamics, bicycle components frictions (tyres, chain, etc.). Read our article on rolling resistance
