175/70/13 & 185/60/13......I would think either size should work for a 1200, maybe a lower profile is needed. Where on the fender do they rub? I have 185\55\14 on my grey coupe with no rub at all and stock suspension (been told it needs more low and also that it looks like a Hot Wheels). When I had 195's on it, they rubbed,
Sadly, I do not have an extra set of 12" slots but do have some steelies.
