Last year when my dad and I started on my car (1984 GT hatchback), we did a 5-lug conversion and put four 17x8 Bullitts with worn out, mismatched 225/50R17's on them. Were starting working on it again and I'm wanting to run 275/40R17's in the rear with 245/45R17's in the front. I know the 275's are too big for he wheels, but are they dangerously so? If so, I'll run 245's on all four corners. I'll also need lowering springs if someone could suggest some that would lower it about 1.5"-2". Thanks.

MM, h&r, but I run Steeda and t hey are exactly what you are looking for. Youll be fine with 275 on 17x8.

You're fine with 275/40-17s on 17x8s. I mean, they're not unsafe. But you don't really use the full treadwidth because the tire rolls up on the edges. (I've run that combo before)

255/40-17 is a closer fit to the rim size.

Thanks. I know it doesn't effectively use all the tread, but from discount tire the 275's are about $25 cheaper than the 255's for some reason for the Nitto 555's that I want. Though I'm thinking now that 255/50-17's on the rear would fill up the wheel wells quite nicely for a bit more of a dragster stance. I'm kind of wanting something like this. He's got 255/50-17 rears and 235/50-17 fronts.

275/40-17s look nice on a fox. I think the 275/50 would look too tall compared to the front.

Here's one of my foxes on 275/40-17s

Nitto 555 are junk buy toyo, Et's, or hoosier.
The reason I want them is that my dad has them on his '04 Mustang GT 5-speed and they grip really well on dry ground, in the wet, and even pretty well in an few inches of snow/slush/ice. What problems have you had with them?
