4 -15” 4 nub bump steel wheels for 6 lug Chevy GMC truck blazer OEM Original. Please look at pictures carefully as they are part of the description. These are original 4 bump wheels taken off of a 78 Chevy blazer. One of the wheels is extremely nice, I’m guessing that was the spare. They fit other years, they are the more desirable 4 bump, not the 3 bump that won’t work with factory gm disc brakes. These are the half ton wheels that take the 10.5” dog dish hubcaps. They have minor dents and dings associated with wheels of this age. They will work with 4wd, I get that question a lot. Very restorable set of wheels. I think with a good blasting and mild metal work they would clean up great. This set of wheels is a little rougher than the other wheels that I have listed, but the price reflects condition. These four bump wheels are getting extremely hard to find. Keep your GM truck all GM with original wheels. Please look at backspacing measurements and width measurements in pictures. Thanks for looking
