Guard Rubbing In 34 Gtr. Offset Or Tyre Profile Problem?

Haha thought that'd be the case! Happy to help mate.

Yea 15mm usually equates to roughly 2.5% so not far off from VIC standards.

Ali, those calculations were based on the standard tyre size being 245/45R18. I assumed these were the OEM tyre size as my car was complianced with these, but just realised that you are in fact correct, the OEM size is actually 245/40R18. My apologies !! And I think in Melbourne you are allowed a difference of 3% in rolling diameter.

Ye a 45 is not factory for a R34, so hence everything you were told = not correct, as Ali has said.

Anyway as part of compliance and what not there should be a tyre placard stating all of this on the car.

Not sure then, how a proper tyre shop, would then get it wrong...
