    Hi all, on my a3 I have some rs6 replica wheels, it's got 235/45 zr18 tyres on, I'm looking to get some smaller ones as they rub a little bit after lowering it. They currently have a bead going round them to protect the edges. Am i able to fit 215/45 zr18 tyres on them and have a little stretch?

    thanks very much

    Do you know what width your wheels are? I'm running 225 tyres on 8.5" wide rims and I wouldn't want to go any smaller. Most 18" wheels run a 40 profile tyre, and 17" wheels run 45 so you might want to address that at the same time.

    Yeah your problem is most likely the profile, for an 18" wheel it should be 40.

    Ok, cheers! I will put some 225/40 on it next. No idea why it had 45s on it! Thanks again.
