What’s too big on the 18s? They must have the same rolling radius? When I put BFGOODRICH All Terrains on mine I increased the profile and Therefore the outer diameter by about 5 percent. I had to lower the pressure to 10psi to fit the 5th wheel in the carrier. I carry a compressor so it’s not an issue. Have you considered doing this?What is the size & designation of the wheel please? I need to get one & my 18" alloys are too big?
