Sorry to bring up an old thread - but seemed better than starting a new thread!

I've currently got 165/55 r14 tyres on my K3 and I was wondering what sizes people are running on their cars as I need to go slightly wider as the tyres are pretty stretched at the moment, I've got arch extensions sorted so could probably get away with anything up to 185 width wise on the front and not really limited on the rear.

I'm really interested on what size people have run without contacting that arches, whether it's r13/14/15.

Thanks
