Mountain Bike Tire Pressure Rider Weight

I just to give you an idea of how exclusive it is to the rider i weight 235 and on a 29 with 2 2 tires i ride 20 front and 25 rear.

Mountain bike tire pressure rider weight. Someone who weighs 130lbs will run less pressure than someone who is 160lbs. To find your ideal pressure start in the middle of these ranges then factor in your body weight. Id say the best tire pressure is the one that works for you and you don t find it by a guide. To work out the correct air pressure for your mountain bike tyres use the following approach.

The wider the rim the lower the tire pressure you can get away with due to surface area and volume. Road tires typically require 80 to 130 psi pounds per square inch. Stan s notubes offers a simple formula as a starting point for tubeless tire pressure for most xc riders. Mountain tires 25 to 35 psi.

Lower pressures can also result in lower rolling resistance offroad as it takes less energy for a tire to deform around an obstacle lower pressure than it does lifting the bike and rider s weight over it higher pressure. This also makes for a more damped ride feel and improves traction and comfort on both climbs and descents. Don t be lazy go out and try different pressures but i will say less is more.

For example a 145lb 66kg rider might find that 35psi in a 26 x 2 25in tyre feels too hard and lacks traction. Use the tips on this page to make adjustments to this value depending on your individual needs. Narrow tires need more air pressure than wide ones. And hybrid tires 40 to 70 psi.
