20s X 4 on My 68 SWB GMC
So advice on running 20 X 8.5 on all four corners on my slightly lowered truck (68 SWB GMC)? It's got 275-60-15 BFGs on 15 X 8 rallys with no clearance issues at all. Here's pictures of My GMC as is and a photo-shop of it approximately how I want it. The other truck is my friend Mark's with Boss wheels I'm looking at Coys C5s, American Racing TMs and Boss wheels in the same basic Style and Size, Glad to hear anyone's take - THANKS - Lee

I have Boss 338's 20" all around with minor rear end clearance but a 1/4" spacer solved that. They where scrubbing inside fender on hard bumps. I had to grind the front hub down just to get the wheel cap on it. The picture has all my info in it.

Re: 20s X 4 on My 68 SWB GMC
Thanks Andy for the info. My friend's truck with the 10 wide Boss's on the rear rubbed too, same thing he spaced them successfully. He also tried 18" Boss up front but has since gone 20s all around due to appearance. I'm leaning more toward Boss now

LMK. A guy on our facebook page can get them pretty cheap with tires I think less than $1400.00. ![]()
