195/45/16 tyre pressures

What should the fronts and rears pressure be on these tyres plz?

Thanks.

what ever the "standerd" nova pressures are buddy, its about the weight of the car not the tyre :wink:

[Aragorn]

no its not the nova manual has a list of different pressures for different size tires

i normally do around 30-32 on fronts and 28-30 on rears

[LukeManic]

yer, i did know that they would be different - reason i asked, its not gonna be the same at all as its a big tyre! :P

the size of the tyre really makes naff all difference.

the contact patch will generally remain the same size, jsut with a wider larger diamtere tyre the patch changes shape a bit.

SO technically the Std book pressures are fine. but to get a benefit from good tyres, good suspension etc then you need to boost up the pressure by approx 3-4psi to stiffen the sidewall of the tyre up a bit.

I may be wrong but....

Pressure=force / area

as the weight of the vehicle is the same (force)
and the contact patch is greater (area)

surely in theory the pressure should drop!?!?
