Firstly, road bike tyre pressure usually requires the front and rear wheels to be inflated to the same pressure. The only exception to this would be the fitting of two different tyre models, each with a different recommended pressure. The next thing to consider with road bike tyre pressure is the tyre section width and most importantly the weight of the rider. The heavier the rider, the higher the bike's tyre pressure should be.
The usage, the terrain you ride on, and the weather conditions are also parameters taken into account for the ideal pressure. Remember, if required, we advise you to consult the MICHELIN bicycle tyre pressure chart to convert these figures to PSI.
Here is how it works:
First, find the detailed recommended bike tyre pressure for the tyre model fitted to your bike.
Then, look at pressures written on the tyre wall*
MICHELIN recommends pumping the tyre until the tyre bead is properly seated on the rim (without exceeding the maximum pressure on the tyre) and then to let some air out by tapping on the valve until your bicycle tyre pressure gauge shows the tyre inflation level is back within the recommended parameters (without going under the minimum pressure limit). Having done this, you will immediately notice that pedalling becomes easier.
To perform, the tyre must have a correct contact patch on the ground and a correct stiffness on the tyre wall.
If the tyre is too hard and the tyre walls do not move under the weight of the rider, decrease the pressure. It will extend the surface of the contact patch and improve comfort and grip performance.
If the tyre is too soft under the weight of the rider and the tyre wall deforms a lot, or if you often get a flat tyre due to pinch shock (snake bite): increase the pressure, it will improve handling and will prevent against flat tyre.
