Re: Can I use 15 x 10 wheels on my \'95 Dodge Ram???
Stock backspacing is 5". I run 305/70R16's with no lift on 16x8's with 4.5" of backspacing. 3.75" of backspacing looks alright but the wheels stick WAY out of the wheel well. I'd stick more along the lines of 4" or 4.5". And I personally wouldn't go with 15x10's on a 12.50" tire. 15x8's should work fine.
I would think a 15x10 with the backspacing your talking about would rub like crazy on the fenders while turning as well.
