That sounds like a pretty thick sidewall for starters. But depending on the offset, hypothetically the wheel could stick out beyond your fender (low offset) or be sunken inside the fender by as many as a few centimeters (high offset). There's no way of knowing that unless you know the offset of the rim, no matter what the tire size is.
Judging by the options they have on ModBargains, if they are
- front 8" ET40, and rear 9" ET40 they'll fit no problem
- front 8" ET40, and rear 9" ET20 the rears will poke out and might not be to your liking. And if you ever lower your car you will have to get thinner tires and roll your fenders.
