I'm trying to figure out what wheels to order for my 2003 X.

I'm looking at the Rock Crawler Series 97 Wheels. According to 4wheelparts.com the bolt pattern for the 2003 is 6on5.5.

So I was looking at these rims: 15x8 Size 6x5.5 Bolt Pattern 3.75" Back Spacing, but I'm not 100% sure on what I need for back spacing. I understand what back spacing is but what is normal for the X?

I'm also looking at getting Bridgestone Revos @ 31x10.5x15

Any input would be great.

Thanks
Troy
