Does anyone know if 15inch rims fit on a 2020-2021 gladiator?

Your best resource would be contacting several aftermarket wheel manufactures... Probably NOT...engineers put rims at specific sizes to clear brake calipers & rotors; thus 17's being the most popular & what comes on the Gladiator. I believe it is a 5x5 lug nut pattern & when reading of others using JK wheels the star locks for the rotors must be removed so the wheel mounts properly.

I'm not sure on all models... but they will not fit on max tow packages because of the large brakes.
