i know this is a dumb newbie question, and i did search but-I got a 74 chevy blazer K5, I want to buy some hummer rims, they have 7" back spacing. Will 7" of back spacing work or will it be to much? And how is back spacing measured? From the inside of the rim or from the out side of the rim to the center?

Back spacing is measured from wheel mounting surface on back of rim to the outer edge of the back of the wheel. Check the link below for reference.

If they are 8 lug full width chevy axles, a stock hummer rim will fit on the hub (same 8 on 6.5 lug pattern) BUT I am not sure if there will be any clearance issues with steering. The rear should not be a problem, the front I am not sure. Might need a small spacer?

Maybe someone else will chime in with an answer to that one?

I think you'll hit the tie rod ends up front. I'd be running around 3.5" of BS if I were you.
