Stock wheel question/problem

Fitting stock 6 lug wheels to 93 2wd Silverado

Stock wheel question/problem

Postby ronthomp [OP] » Mar 19 2017, 8:36pm

Hi, I'm new to this Forum and need some advice. I have a 93 2wd extended cab Silverado C2500 6 lug.
Some previous owner swapped to 15" custom wheels. I am trying to go back to stock 16" aluminum wheels. Every wheel I have bought used has rubbed the upper control arm on both sides, scratching the wheels. This has been steel wheels as well as aluminum.
The question is, are there different size stock wheels that must me matched by year?
If not, what could be wrong with my truck?
I even went so far as replacing the upper and lower ball joints, thinking slop may have cause clearance issues. This had no effect.
BTW, the 15" wheels do not rub. The problem only showed up when I changed the wheels.
Thanks for your time.

Theres others here that know a lot more about this then me, but I think it's an off set problem, as in the wheels you've tried sit to far into the wheel well.

From what I can tell, it seems that truck came with a 6.5" wide wheel, which for today's standards is a SKINNY wheel. Although they are only 6.5" wide, the stock wheels still have about 5.5" of backspacing which is a lot for a wheel that is only that wide.

What wheels have you tried? This way we can figure out what is going wrong.

Thanks for your time. The stock wheels I bought used have markings on the inside that appear to say 16x7.0-something-x31. The casting is hard to read, even after wire brushing. So I guess there are different size stock wheels? Again, thanks for your time.
