Getting the right amount of pressure in your tires is very important in all sorts of bikes, especially mountain bikes. You should learn how to set it right so you will have more fun and fewer accidents. If you set the pressure too low you will have trouble to pedal and you can get a flat tire. If you put too much pressure you will suffer from a bumpy ride and have less control of the bike as well.
Different people will have different amounts of tire pressure in their tires. It will also wary by the tire’s condition and what kind of terrain you are riding on. You should use a high-quality pump to easily chance your tire pressure. Make sure that you have a tire pressure gauge so that you can keep your tires at the optimal pressure.
The manufacturer of the tires has usually recommended the tire pressure that you should use. I recommend that you start there and adjust the pressure if needed. Make sure to use the same pump and gauge always when checking the pressure because different things can show different readings to you.
Higher tire pressure is better than lower. You should aim to have your pressure around 40-50 psi and then lower it from there until you find the optimal one. If your weight a little more you should use a little bit higher pressure on the tires.
You should take your bike to a test ride to see if the pressure is right. Pay special attention to how the bike handles turns and how well it slides down slopes. If you see that you have too much tire pressure then you should lower it by 5 psi at the time. If it starts to feel better then you are good to go. If however it still feels bad then you should lower the pressure more and then check again. Do this until it feels good to you.
