How wide are the wheels on our stock trucks? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey gang,

Looking at replacing my stock 6-luggers with some american racing AR-767's (the black powder coated d-window type) Before I order the wheels I was wondering how wide are the wheels on my stock '70 C10 2wd? I was thinking of getting 15" x 7's". 8"s would be nice but I think it'd be too hard to steer with manual steering. Thanks in advance!

I replaced my stockers with 15X8 ralleys, and I can't tell much difference in the required effort to turn it.

I have 15X8's on all four on my 70cst. Only mistake I made was I put 275x60x15's on the front. To big...The front tires rub the lower control arm when I turn. I'm going to replace the 275's with 255's and all shoud be fine. Also I should point out I have a 81 front end installed.

I have 15x8 with 275/60 tires on my stock 70. No problems what so ever on clearance. I think your clearance issues, especially on the inside are going to depend on your backspacing. I had 15x8 ralleys, now I have some old American Wagon wheels and neither are a problem, although I have not measure either wheel's back spacing.

Hey Palf70Step...
Is your truck lowered? That's where I am having my problems I think? All I know is the 15x275x60"s are rubbing the lower control arms on the front when I turn. Maybe the 1981 front end has a sharper turning radius then the stock front end?

ok, but how wide is my stock wheel???

**70cst** · 03-22-2004, 04:57 PM

Ok back to ts71281 question...I don't think there would be much difference between the 7" and 8" wheels as far as steering effort is concerned. I've driven both and I guess I would have to drive them back to back to be able to give an accurate opinion.
Back to yor question ts71281... I would guess the stock rim would be 51/2-6" in width. Ok guys..Who knows for sure?

Hey WES and Tim...where are you guys at? They would know!

6 inch wide 3.5 offset

I had manual steering and had wide wheels. I was very difficult to turn when moving slow. I suggest that you get the smallest width tire you can untill you get some power steering. Unless you want forearms like a bodybuilder.

ts71281 · 03-22-2004, 05:38 PM

I like my manual steering, thanks

But I think I will go with the 15 x 7's then. Just an inch wider and that's it. Right now I'm running 235 75 15's on the truck and I want to go an inch wider and the same height. Would a 255x60x15 be the same height as a 235 75 15, just an inch wider?

I had some stock wagon wheels with 235/75s and I switched to a 15X8 with 275/60s all around and didn't notice much, if any, difference. I have manual steering too, and I do just fine even in parking lots.
