Wheel and tire sizing question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

BillyBlaze · 08-09-2009, 08:21 PM

I have a 73 cheyenne super 10, I have decided to keep my stock old rusty 15's
Can anyone tell me what width the stock 15's are?
Also i want to put a good sized all terain tire on there...any suggestions on what size works best for the stock 5 bolt rims?
I was thinking of the General Grabber AT2, any other suggestions?
Thanks for the help

It would have had an equivalent of a 235/75R15. If you are wanting to keep the stock theme of your truck, a set of Rallys cleaned up would look pretty good on there. I think your stock wheels are either 15x6 or 15x7, not real wide for any all terrain tires.

15x8's were real common on the trucks too.

yeah, I would like some new rims...or even different ones but am stuck with these for a while...but cant wait on the new rubber.
I cant find any sizing info on the rusty's

They are square holed rally wheels, right? I believe that all original rally wheels have a stamp on the inside. It should tell you what size they are. I would say probably 8"s. Possibly 7"s, gm didn't make a 6" as far as I know. But they did put a 6.5" on vans. If you have to measure them: an 8" rally wheel measures 9" from edge to edge.

I'm not even sure they are rally wheels, pretty sure they are whatever came stock on the 73 year model.

Post up some pics of them.

If they are rusty nothing a good cleaning, and some spray paint won't fix. It will make a huge difference.

here's a link to some pictures.... of the truck in general. It's still at the engine rebuilders at the moment so I can't run out and snap a few pics till I get it back.

15x6, I'll bet. The whitewalls give it away.
