Spare Steel Wheel Replacement

My original 2008 steel wheel is severely corroded and needing replacement. It's 17"x 7 1/2" 16 hole wheel.
I have some across a remanufactured OEM wheel of the matching the original that is powder coated. Is that finish an issue?

I also found a 2023 and newer oem take off Silverado steel wheel, 17" x 8" which is a bit less expensive but the off set is about 1/4" outward (24mm vs 31mm offset) compared to the original 7 1/2" wheel and the inner and outer edges are also 1/4" out and in by comparison to the 7 1/2" wheel. The Silverado wheel is assumed to be factory finish.

The purpose of the replacement is strictly as a spare and will likely live underneath up on the hoist. The tire will be the original spare size as 265/70R17 which the factory intended to work with the Z71 18" wheels with 265/65R18 tires.

Any thoughts on the finishes and the substitution of the newer slightly different wheel?

My '07 has an aluminum rim for the spare. It lived under there till last year and is in great shape. Possibly find one of those?

This will work perfectly fine as a spare wheel. If it's on the front, there will be a slight pull in hard braking or when in 4wd due to the different scrub radius between sides.

Look at the offset of your 18" wheels -- bet it's the same as the 17" Silverado wheel.

The difference in offset between the OE wheels and the Silverado wheel compensates -- splits the difference -- for the slightly wider wheel width. It centers the tire, much like your 18" ones do.
