The first and foremost thing to learn by the every cyclist is the importance of setting tire pressure in mountain bikes. If the tire is correctly inflated then it gives smoothness and control to the cyclist. In contrary there will be danger of getting a flat tire or hard cycling can be caused by low pressure while uncontrollable and bumpy bikes are determined by high pressure.

According to the condition of the tire, the condition of the mountain trail or the personal preferences of the rider the tire pressure varies time to time. You should regulate the tire pressure with a good quality bicycle pump. You will also need an accurate gauge while taking the pressure reading.

You can recommend the best tire pressure by taking a test ride. You can also observe the slides on the mountain and how it runs on the dirt track. You can also adjust the tire pressure by 5psi in each tire. Always go for a standard tire pressure by using the same gauge and pump. Make sure that different gauges will give you different readings for your tire pressure. You need to observe which pressure suits your bike most that is recommended to start with a high pressure in 40 – 50 psi (3-3.5 bar), and then you can lower it down according suit to your bike. Even you can use higher pressure if you are on the heavier side.

You can observe how you can ride without getting flat tires to find the lowest pressure. When the tire compresses against some object the tire flattens and there is a chance of the damaging to the tube.

It is recommended to use low pressure of 30-40psi in case of tubeless systems. The risk of pinch flats is less in tubeless tires and an occasional rim is not alarming. So there will be no problem in running on much lower pressure. Any how you need 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. In fact you do not dent the rims or burp air out along the bead.

Rolling resistance can be another balancing test with lower pressure to your bike. In fact extra rolling resistance requires extra efforts but it gives increased control and climbing traction. So efficiency is important than better control for cross-country racers.

You can determine the air requirement which can be also done by squeezing the tire with hand a common procedure and you can feel of the pressure.
