Mountain bike tire pressure

It´s clear that the tyres form part of the suspension of our mountain bike and are in direct contact with the ground. Therefore, it is important to have an adequate tyre pressure.


The unit of measure for pressure is the bar, which is equilavent to the atmospheric pressure.


With a higher pressure we get a fast easier rotating wheel for smooth ground or asphalt, but we will not have the grip in more irregular areas, as the rebounds are brusque and the tread is narrower and leads to a poorer grip.

Therefore we must take into account some details to achieve a correct pressure.


 
 


-Type of terrain: That we will be cycling on. The rougher the ground the less pressure we need in the tyres, thus increasing the grip.





-Rear or front tyre: The front tyre should have less pressure than the rear one, as it is the one that receives the first impact from the ground, it controls the steering of the bike and doesn't hold most of our weight. However, the rear tyre does support our weight so the less pumped up that it is, the tread is wider and the pedalling is harder and in the case of using inner  tubes there will be more possibility of a puncture.

-The weight of the cyclist: Must be according to the tyre pressure. The higher the weight the higher also the pressure.


-Type of MTB tyres: Depending on the type of rubber they will need more or less pressure. The harder the rubber the less pressure we need. If they are tubeless thay support lower pressures better.




How to find the ideal pressure?

 With low pressures we will achieve a safer and smoother ride. So, for this reason the best pressure for our tyres has to be the lowest possible, always when there is no risk of: puncturing the inner tube, excessive tread or risk of skidding.



The exception to the rule is to use the mountain bike on pavement, we should inflate them to avoid excessive contact with the ground.
if we doubt, it is best to be generous with the inflated before going out, making small discharges of 0.2 or 0.3 Bar, until you find the ideal behavior of our tyres.


The ideal pressure.
As we have explained above depends on several factors besides driving preferences. But suitable pressure must be within the following limits.

-Mountain trails:  1.7 to 2.2 Bar.
-Tracks:                2.0 to 2.5 Bar.
-Asphalt:              3.0 to 3.5 Bar.
