Grigg, the dodges are the only one I know of that measure right but I’m sure there’s more. I know the 19.5 GM stepvan wheels I had on my old 1 ton and like I think you have on your GMC are too small. The 8r19.5 would be my first choice but they are just too expensive, not so much for steer tread but the only drive or mud treads available are from the top name brands and you’re talking $350 and up apiece. I know I could go with steer tread tires in the back but it’s just not the look I want. I like these: https://www.tirerecappers.com/tires/mud-terrain-tires/lt22570r19-5-retread-lug-mt/
