Anybody running 15 x 7 rallies on the rear? What size tires are you using? Got pictures? I have recently completed my car BUT I am wishing I had to go with 245/60/15 instead of 245/60/14.

I have run 245/60/15 on both 15X7 Rally II and 15X8 snowflakes. First pic is 15X7 crosslace with 235/60/15. second is 245/60/15 on 15X8 snowflakes. second pic also shows 14X7 snowflakes with 215/70/14's.

I have 245 60 15's on the rear but have the 15X7 rally's with 4" backspace.The normal 4.5" backspace is VERY!! close to the frame!!!

Thanks for the responses! From what I can determine the 245/60/15 on a 15 x 7 will give me the same sidewall and and same threadwith as I have now with the 245/60/14 on a 14 x 7. The only difference is the 15" tire diameter is 26.6" whereas the 14" is 25.6". Ponchro, when I measure my backspace, I measure from the drop inside the rim, not the outside lip. When I measure from the drop, I get 4 inches on both my 15 x 7 and 14 x 7 rims.

You need to measure to the outside of the lip!!

I have run 15x7 (4.25 BS) on the rear with 205/65r15 tires, no problems but same combo did rub the a-arm in front.

Now run 15x8 with 235/60R15.

Have also run 15x8 vette aluminum rims with 255/60R15
