But normal 17" donut used together with oem rims & stock primacies? Or even if with other type of rims/tyres but of stock 17x7 & 215/45/17 sizes? I never intended to go for wide rubber while on NA anyway .. donut is there just as more usable fix in a bind then stock tire fix kit to go 25-50km with easy on throttle at or below legal speeds till closest tire shop.
Well, if it is that bad even if with stock wheels for diff, then of course i can replace with front one. Just more time/work, hopefully not in bad weather conditions

. I guess chosen 17" will be easier to fit on front then 16" even if some BBKs are installed ..
