Tyre pressures car manufacturer vs tyre maker ?

[HealyC]

The pressure on the tyres are for if your carrying around a load of chubbies the whole time aka max load

32-35psi all round.

The specs for mine in the door jam are very low , 1.8 front 2.2 rear. With that I was getting edge wear on my tyres.I'm now running more like 2.0/2.2

Theres a number of options on the door jam , you have different size wheels tyres etc then you have fully loaded 4 adults full boot then there's just 2 adults up front seperate pressures for these

R18 ,minimum 2.4 bar up to 2.7 bar ,all around for not hot irish climate . i had my e39 with R18 ,got it with around 2.2 - 2.3 bar all around ,tires was new and used up to 2k mls ,and they there worn on outer sides ,thats mean too low pressure .got them up to 2.6 bars and they there worn to death all straight and full tire

Thats what iv been running on the rear for 2 years now 2.6 I get good even wear right across the tyre fronts I run 2.3

Anything lower and it just looks like iv a slow puncture on the front

Looking through the manuals here is well the heavier the engine the higher the pressures, much higher
