Importance of tire pressure for mountain bikes

Because the importance of tire pressure mountain bikes is high, one of the first things a cyclist needs to learn is its importance. Smoothness and control is determined among other things by correctly inflated tires. Getting a flat tire or hard cycling can be caused by low pressure while uncontrollable and bumpy bikes are determined by high pressure.

There are a few things on which pressure depends and varies, like the condition of the tire, the condition of the mountain trail, terrain type or the personal preferences of the rider. Regulating the tire pressure can be done with a good quality bicycle pump. Also, to take the pressure reading, you will need an accurate gauge. To find out which pressure suits your bike most is recommended to start with a high pressure (from 40 – 50 psi) and then lower it down. On heavier sides is recommended to use high pressure.

The best tire pressure is determined by taking a test ride. Observing how it slides on the mountain, how it runs on the dirt track or how it hooks up in corners can help you in determining the right value. Drop the pressure 5psi in each tire if the pressure is more. Make it the standard pressure only if the new pressure compares well and is more stable and the grip on the ground has improved. If not, rerun the test and drop the pressure marginally.

Observing how you can ride without getting flat tires can help you find the lowest pressure. When the tire compresses against some object and the tube gets damages a tire flattens.

In case of tubeless systems, is recommended to use low pressure (30-40psi). The risk of pinch flats is less in tubeless tires and an occasional rim is not alarming. Because of this, you can run on much lower pressure. It is recommended to be careful when it comes to low pressure because the on a too low pressure the tire will roll under the rim during a hard cornering.

Rolling resistance can be another balancing test, done trough lower pressure. Because it requires extra efforts, the extra rolling resistance gives increased control and climbing traction. Better efficiency is important than better control for cross-country racers.

Determining the air requirement can be also done by squeezing the tire with the hand, giving you a feel of the pressure.
