Hi guys, I am looking to get some 19" rims for my S3. I currently run the stock rims and tyres (225/40 R18). Should I be looking at 235/35 R19 tyres as they only seem to be 1.6% larger in diamerer and won't offset the speedo too much? I'm also considering getting ABT's 400hp chip so wider tyres would benefit the extra torque? What tyre sizes do you guys run with 19" rims and why? Cheers! Regards from freezing Finland.
