Im looking to put a 275/60/15 on the back of my Formula, Im also going to order a new set of wheels. Im just not sure how much backspacing to get on them. A set of 15in Cragar steelies with 4in of backspacing and 255/60s stick out a little from the wheel wells. I dont think 4in of backspacing is enough. Can anybody help me out?

 

that all depends on how wide the wheels are. backspacing is meaningless without also having the wheels width.

 

I'm sorry. I thought I had that up too. I was planning on ordering a set of 15x8s from Bassett. The Cragars are also 15x8. I read some other threads that said for a 275 tire on a 15x8 rim that a 5in backspace was recommended. Is a 15x8 with 5in of backspace what I should order?

 

5 would be better with the wider tire, but may still rub a little in the front of the inner fender well, down low. not a big deal. the factory "rear" 16x8's are 5.125 BS.

you should be fine

 

Thanks man. But I looked at Bassett's website again and they only offer their DOT wheels with up to 4.75in BS. Is that going to be enough? I don't mind if they stick out a little from the wheel wells, but I don't want it to look ridiculous.
