Rears are 4.25” between the rim lips, 4” in front. Front tires are Austones from Universal and are British taxi cab tires, 175/16. Rears are Durvais, 235/85-16. I use bead sealer since all the tires are mounted tubeless and the rims were slightly pitted at the bead. Rims are mid 30s Plymouth artillery wheels 5 on 4.5” pattern.
