205/65x17" Michelin or Continental are standards here in Brazil. I put a 235/45x17" and it's ok.

On the Australian A3 1.8, the standard tyre size is 205/60 on 7J x 15" rim. You need to keep the same overall rolling diameter to avoid affecting your speedometer.
A rule of thumb is for every 10mm increase in width, drop 5% in profile. For example, to go to a 215 width would involve going to a 55 profile tyre, thence a 225/50, and 235/45.

Take a look at the web page I created below. Type in your old tyre sizes then try new ones to see which gives the nearest rolling circumference.

For 18's, I would reccomend maximum wheel width of 8 inch and tyre size 225/40/18<ul><li><a href="http://www.simonprickett.btinternet.co.uk/Car/wheel.htm">Click here</a></li></ul>

Would the 17" TT rims fit an 2002 A3 ?
