Nice one, thanks :beerchug:

I got a stupid question...
On my Passat I have standard Highline 15" alloys... I am thinking to getting an upgrade to 18" alloys... Will the tyre preasure stay the same?

If not how do I work out what I should be putting in?

No I don't think is stupid. I have 225/40 17" instead of the 195/65 15" and like you I cannot check. Somebody somewhere said that the pressure should not be any different regardless of the tyre size. Me I am not so sure as the force at any point on the tyre will surely be different as the surface supporting the car changes with tyre width, not to mention the difference in stiffness on a lower profile tyre.:confused:

The reason it stays the same is because as you know pressure is measured in psi (pounds square inch) so if you have a tyre a huge tyre with say 200 sq inches of volume or you have a much smaller tyre with say 75 square inches it's irrelavent as the pressure is per square inch (so the pressure is the same no matter how big the tyre is just takes longer to pump the bigger tyre up).

Malc, how dare you display that so called "Ultimate Driving Machine" Logo on this forum? :mad:

Euroslap you make good sense - Thankyou.

Though your note about my BMW avatar is not good sense.

Euroslap this seems to make sence!

In relation to Malc's logo... Well I am a ex BMW driver... I think he has got guts to display it! lol
