Tyre wear related to your experience
In mountain biking, experienced riders generally ride faster than beginners, but they don't necessarily wear out their tyres more quickly. Thanks to their experience, they tend to handle their bikes with more confidence and lock their wheels less often. For the same number of riding hours, beginners generally wear out their tyres more quickly because they lock up more often. If you're just starting out, don't worry! With time, you'll learn to tackle courses with more confidence.
Tyre wear related to track knowledge
In mountain biking, familiarity with the route is also a factor. If you're familiar with the route, you'll ride with more confidence and will therefore have fewer wheel lock-ups than on a new, unfamiliar circuit. In the latter case, natural caution is called for, with more braking to avoid being caught out, which has an impact on tyre wear.
Tyre wear related to incorrect tyre pressure
On a road bike, the tyres have no tread. As a result, tyre pressure has little impact on wear. This also applies on City and specific gravel tyres such as the Power Adventure, which do not have a deep tread pattern.
But on off-road rides, over-inflated tyres can have an impact on wear: the contact area is reduced and the effort is therefore applied to fewer studs, which will then wear more quickly. Also, as an over-inflated tyre deforms less, it loses grip potential and wheel lock-ups are quicker and less controllable, leading to slipping and therefore premature tyre wear.
Choose a low-pressure tyre instead. In this case, the contact surface is wider, offering more grip and less slippage under braking, which results in slower wear.
Tyre wear related to the terrain
Wet / dry ground
In mountain biking and gravel, less wear is observed on wet terrain than on dry terrain. Even if there is some slippage, humidity involves less heating up and therefore causes less wear.
