Gt turbines

I belive it's a 275-50-15" for racing and I bet you could pull off a 225/60 on the front, 245-50 on the rear for street

It's Gumby's fault.

I've been wondering if 235/60's will fit front and rear for street, but maybe not. Has anyone tried it? I'm running the standard 225/60's now.

Before I went 5 lug, I had 275/50's w/15" rims in the rear, but that was with the adjustable springs in the back. I'm pretty sure 235/60's will fit both ways. I think my front tires were 215/60's, and that was with the springs cut and the 4 lug custom 15" rims. I'll have to go look at them.

14x6?

Nothing wider than a 225, and that's pushing it.

I had 275/50/15's on the back of mine at one point too, and 235/60/15's up front with no probs.  They did rub on big bumps with a passenger though, or entering a steep grade driveway.
