MTB tire sizes and pressures
The impact having the right tire selection makes on your riding experience cannot be overstated for mountain biking. Along with this goes selecting the correct size to match you rims and then the correct tire pressure to match your weight and riding style. Then of course you have to factor in how hard the surface is you are riding on - the harder the surface the higher the pressure. The below table will give you an indicative starting point but there is nothing that will replace your own experimentation to find you own perfect fit. We have assumed hard trail conditions. (Number below refer to rear tires, front tire should be 1-2 psi (0.1 bar) lower).
Note - The tire sizes below are a starting point from which to make a calculation, they do not indicate a recommended tire size for the wheels. For those please refer to the individual product pages.
Never exceed tire manufacturers maximum pressure.
