Stock wheel specs?

[94SL]

I am assuming the stock wheels are 15X8, 3.75" back spacing. Can anyone tell me if that is true?

Thanks in advance.

Depends on your truck, but this should help you out. http://dwtracing.com/chevrolet-wheel-size-guide/

RawbDidit, I saw a column for bolt pattern, 5x127 (5x5"), didn't see anything on back spacing.

96 c1500 silverado alloy wheels. I measured mine before i bought some new wheels. 15x7, 5x127mm (5x5), 4" backspacing.

only place I found that had good reference to match my measurments was https://www.wheelsforless.com/GM_Truck.htm .

Yeah that 3.75" backspacing on a 15x7 is squarebody stuff. GMT400 has more backspacing as delta_p indicated.

Been out of town over the holidays, but right before I left got a good deal on some new/take-off 23575r15 tires. I want to mount them on something different than the wheels I current am running. Is a 15x6 wheel too narrow for a 235 wide tire? I was wanting to use the old square body steelies with GMC hub caps. Like this but GMC not Chevy.

15x6 shouldn't be too narrow for a 235, I run 265/75's on my 16x6.5 PY0 rims.

For this question regarding any tire/wheel size, use Tire Rick's website look up your tire size pick a brand (yours or similar if not available) and click 'specs' - you'll see manufacturer recommended wheel width range.

What is the width of the 2wd 1973-87 1/2 ton truck base rims, 6", 6.5", 7"? I am getting conflicting answers. Talking about rim like this. If someone can measure, one, I'd appreciate it.
