wheel offset help!!!!

I have an 02 sonoma 2wd, and a set of some 18" ADR's with a 38mm offset that was on my acura that got totaled. I am gonna buy adapters and I am not sure what size I need (1.25", 1.5", etc...) could someone please help...

offset depends on width, so how wide are your 18's?

If for example they are 7.5 inches wide with 38 offset, from my understanding you want from +12 or closer to zero offset, so 38mm/25.4 (mm in inches) you would buy a 1.5" spacer to get to zero offset, or 1.25 to get to +12.

That help?

here an idea sell your 18" adrs on ebay or to somebody and purchase the right rim with the right offset for your truck. dont be cheap with the wheels, i sell 20" rims at my store for 135.00 bucks each, i use to buy ADR's for 75.00 each how much are you spending on adapters?

Thanks Russ-D, that answers it.
