Thread: Lowering tyre pressure not the answer?

120 is a good number

the 4psi rule is good for most on road and some sand (sustained low speed at a constant stable sand temp) conditions but not much chop otherwise.


Normally for road use if you have your pressure right once the temp comes up you go over your target pressureby 4 psi. if you start at 28 and you chekc them after an hour and yovue got 32 and you get 32 gain an hour later youve got the pressure about right for your current operating conditions.

My caveat for using it in sandy conditions is that the pressure rise should get you to your target pressure. but you have to be careul if your target pressure is lower than 15 psi or you air up hot tyres to a low pressure on a hot day
