Nice. What brand are those? I run Nittos at 315/50-15, on wheels with lots of backspacing. I think about 6".

Re: 315/60/15's

What width is the rim? I have a 15x12 315/60/15 with a 6in bs laying around and was wondering if it would fit

Re: 315/60/15's

I think 15x12 with 6" of bs may not be enough..

The rims are a Mickey thompson et drag. they don't make these any more... tried to find a front wheel that is close to matching, so I had centerline make these in 17x7 for the fronts...I think they will look ok..

Re: 315/60/15's

I have the same. I got the last pair before they were discounted. Bought them for my 78 Malibu but are just a little too big lol yeah I wish I can find front ones.

Re: 315/60/15's

Thought I was the only one with these rims...lol..
I think these centerlines will look pretty close...

Plus I like the look of 15s out back and 17s up front.

Re: 315/60/15's

1.35 is awesome....

Since these are 30" tall, would a 225/60/17 or a 225/65/17 look better on the front?
