hey guys, just a quick one really what tyre pressure should i inflate my p38 they are getting really low and need some air but dont wanna put too much in or not enought lol confused.

This thread has to prove the case for checking tyre pressures, oil levels to be included in driving test.
 
It is. Has been for about 6 years.


Well most of the new drivers i know don't have a bloody clue how to do it. So it must be in one of the multi choice questions that don't get asked to often. I meant practically demonstrate that they know how to do it.

Tony help me here: keep seeing it posted to have more air on the back axle instead of the front?
Why less air on the heaviest axle weight ?
and more air in the lightest axle weight ?
 
as i know that you have to put different air pressures in the front than the back ones i thought i would ask, i do know how to check all oil levels and treads and air pressures on tyres as a driver who passed in 2006 i know a hell of alot more than most who passed in the same time. and i know for a fact that i could put most of you old gits to shame on knowledge of cars, 4x4 and rangies im just new to owning one that doesnt mean to say i know nothing, just thought i would ask bout the pressures as they are different.

It was just a ribbing mate don't take on so. As for your knowledge of cars, 4x4s and Rangies i seriously doubt that. Don't throw gauntlets down you will almost certainly come out second.:):):)

That is the spec John, it says 28 front 38 rear under all load conditions. If the arse end was fully loaded there would be more weight on the rear axle. But can't see why 10 psi difference front to rear IF the rear is always light. Discos are the same. So i suppose you could run with less in rears but you would have to increase pressure if you loaded it up.
 
For what it's worth, the book figure is 28psi front 38psi rear in all conditions for 18" rims. I run mine at 28psi front and rear unless it's loaded, it tramlines with 38psi in the rear unloaded.
 
Re tyre pressure..

I was led to believe that due to more weight and stress on the front the tyres heat quicker, once hot, the internal pressure increases and they even out with the rears. Lower pressure on the front also gives understeer which is considered more manageable than oversteer...
