I've searched the forum for about an hour now, but I still haven't found quite what I'm looking for.

I'm looking at buying Cragar Soft 8s, but I'm not sure what size to get.

I've got 15x6 wheels now, and from what I understand these wheels have a 12.00mm offset and a 5" backspace (please correct me if I'm wrong).

The Cragars I'm looking at are 15x7, so what size should I get regarding offset and backspacing? I've got 31x10.5x15 Bridgestones on my wheels now and I'll just have them mounted on the new wheels. I'll probably be ordering the wheels from Summit, but if someone else has any recommendations please let me know.

 

If this can help I bought rims Cragar at summit.

I've been shopping for the same thing, Summit, Jeg's and JC Whitney are the same price so it doesn't really matter where you get them. If I were you I would just get the 15x8's they're a better fit for 10.50's and if you ever want to go wider you'll already have the wheels for it. I'm running 32x11.50's on my stock 15x7's and I'm going to get the 15x8 cragars. Also they only come in one backspacing (I think the 8's are 4.5") so you should be fine.

 

I wouldn't mind 15x8's. My only concern is them rubbing or grinding against the wheel assembly. I would assume the 4.5" backspacing would help that, but then again if I get 15x8's then thats an extra two inches of thickness over my stockers...

 

My 15x7s are 4.5" backspacing and i believe at the 12mm offset...and it's all good. got some 31x10.5s on them.
