Tyre Pressures

[Ronaldw]

When I got my calais there was not a tyre placard on the car(it's on order) but what is an appropriate tyre pressure for the standard Calais wheel 17x7, I keep 32lbs in them but would more be better??.

Depends... The recomended pressures are more for lower noise and more comfort. I run 38psi all round in my R8 Clubsport... Better grip, slightly harsher ride but I don't care.

Try 35psi in the Calais - it's what I used to run.

i have 17x8 rims and i run 38-40 in them, bit bumpy but feels nice

I run 38 Psi in my 17x8 rims because thats what was recommended when I had my new tyres fitted.

I think thats why thay put the little sticker on the car (inside driver door space)

1 more thing ... what kind of tires were on the car when you first bought it ??
I want to see if it depends on the country

Boy1236, if you read my thread you would have seen I did not get a tyre placard fitted to the car when I picked it up!.
The tyres fitted to the Calais are 225/55R17-97V.
I will try 36lbs then move up, at 32 lbs it tended to strain the power steering a bit.

Ur running low mate, go at least 40!!

the placard will say 26 ~ 28 psi
i only run 32 psi max
sidewall tire pressure 35 psi max as per manufacturer (firestone/bridgstone)

 

[Umai Naa!!]

I set anything with a 17 or larger to 40psi on customer's cars.

It stops the edges from chopping out.

If you set the tyre pressure high wouldn't you get more wear in the centre of the tyre??
