Tubeless Mountain Bike Tire Pressure Chart
For mountain bikers the maximum pressure rating generally isn t the issue because most riders run well below this number especially with tubeless setups.
Tubeless mountain bike tire pressure chart. The technology uses a. If your pressures are too low you. Road tires typically require 80 to 130 psi pounds. Mountain bike tire pressure that is too high will make for poor contact with the ground and a less controllable ride while mountain bike tire pressure that is too low will make your tires behave unpredictably and will make them susceptible to.
The narrower the wheel the more pear shaped the tyre will become under pressure. Typical mountain bike pressures range from 22psi 1 5 bar to 35psi 2 4 bar generally with more air in the rear than the front. Mountain bike tire pressure is the ace in your back pocket. Stan s notubes offers a simple formula as a starting point for tubeless tire pressure for most xc riders.
For the purposes of this post i ll be referring to using a tubeless tire set up. Riding with an appropriate mountain bike tire pressure can make a huge difference in how a ride feels and how much control you have over your bike. The pressure value is calculated considering a tubeless set up intended road surface rider s weight average bike weight inner rim width and tire volume. However the perfect tire pressure for a tubeless tire also depends greatly on the factors already mentioned and as such vary depending on riding style and terrain.
A higher number of g recorded for a given tire pressure and cadence indicates that less of the bump acceleration is being absorbed by the tires and the bike and more is transferred to the rider. For cornering and drifting this can be risky for the tyres as they will become compressed over the edges of the rims. For a 140 lb rider that would yield 22 psi rear 19 psi front. As mentioned previously tubeless tires can be run at lower pressures without the danger of snakebite punctures.
For those unfamiliar riding tubeless means that you don t have tubes in your tires. It can dramatically change the experience of a mountain bike ride. This is because more of your weight is on the rear so it needs more support. Divide your weight in pounds by 7 add 2 psi for the rear subtract 1 psi for the front.
