Can someone tell me if a 205/50/15 will fit under (rolled) guards on a 1200 with 15x8 wheels with 0 offset or do I need to go to 185/5015
cheers

Ive had issues with tyre rub at over 185. But I don't have a clue what offset I got.
1200's don't suppor big tyres easily.

thanks.

have gone for new 15x8 rims with 185x50x15

the car is back from getting painted so looking forward to putting it back together

cheers
