backspacing on oem rims..

[yukon8402]

I am currently sourcing rims and looking at STL1622U45 / (GM-9592306) and STL5128 / (GM-9595393). The 5128 is the stock wheel and the 1622 is stock for GM 1992-2000. I was curious if anyone knows the actual backspacing and offset for these wheels. i can not find anything from GM and none of the wholesalers seem to know either. thanks in advance.

Your wheels should have the size and offset molded into the backside of the rim. Pull one and look.

The 5128 has an offset of 28 mm and a backspacing of 4.85 Inches.

The 1622 has an offset of 49 mm and a backspacing of 5.68 inches.

I had only once source for the latter wheel's offset and I like to get 2 or 3 before relying on that information.
