Optimum backspacing - The 1947 - Present Chevrolet & GMC Truck Message Board Network

YBNORML · 09-06-2011, 08:53 PM

I am looking at a set of 18"x8" wheels. The seller tells
me they have a 6.25" backspacing. I will test fit on the truck before purchasing, however the seller is about an hour away. So I don't want to waste my time. The truck is a 1998 extended cab shortbox 2wd. The truck will
be dropped 4/6 when done. There is also a possibility they may be 9" wide. He is at work and couldn't remember.

6.25" would be a TON of backspacing for an 8" wheel. My 10" rear wheels only have 6" of backspacing. 6.25-6.5" would be more optimal for a bagged truck (on a 10" wheel), but I like the deeper fronts and they work with my setup that doesn't quite lay frame.

My front 8" wheels have 5" of backspacing, which is just about right.

I thought they might be a little deep, I think I'll give them a test fit anyways.

What are they coming off of?

Supposedly he had them on a 1991 reg cab. But I have learned to never take anyone's word for it. Especially where money is concerned.

Not yet, work has been busy. I'm hoping to get it done on Friday.

Ha Ha, Not a chance, they wouldn't even fit over the hub on the fronts. I'm pretty sure they were jeep wheels. Turns out he used spacers in order to run them on a chev truck. Information that would've been nice to know earlier

Nice. FAIL!

At least you didn't shell out any dough.

**Boog** · 09-11-2011, 08:54 PM

Whew! Close one.

Craigslist strikes again (I'm assuming).

It was Kijiji. Do you guys have that stateside? Essentially the same as craigslist.
Incidents like this are exactly why I insist on verifying things for myself. Before laying down any moola
