WHEEL AND TIRE SIZING HELP

[gbodyera]

Hey guys. Im picking up a set of 15in Cragar SST's to throw on the Cutty. The front are 15x6 and the rears are 15x10.
I dont know too much about small rims and tires. I want some pretty fat and wide tires on the rear and ok size on the front. ANd I may get some BFG's, idk yet.

What size tire you guys running with 15 in rims? PICS ARE BETTER THAN WORDS!!!!

might wanna be carefull with the backspacing on the 15x10s...
Ideally, you don't wanna go much wider than 8 on the back with these cars. And on a 15" rim, you can still get some big tread on there.

I would recommend 215 or 225 on the front, and 255 or 275 on the back. both in 60 series...

You may hvae to notch the frame with those 10s, or if the backspacing is good, then you may get away by rolling the fender lip.

hope that helps...

The guy said the 15x10's have a 4" backspace. I think Ill be ok.

I'd test-fit those rims before spending any money on tires for them.
I think they're gonna be too wide, but I've been wrong before...

Can I stuff some 295 50 15's on the rear? If so what do I match the front with?

I think with a 10" wide rim, with only 4" backspacing, the wheel will stick out too far. The tire will definately stick out past the body lines.

A 295 tire on a 10" rim is no problem. But since it will stick out soo much, it may cut itself on the fender skirt lip when the car hits a bump. You will need to roll this lip in.

Why not go with a 8" rim?
With a 8" rim, and 4" backspacing... you won't have any of these problems. And you should still be able to do a 275 tire, and go taller, like a 60series (275/60R15), which may look better in the end. And give you more traction.

I still think 225 is a good size tire on a 6" rim...
