Rims
I understand that to measure the width of a tire rim you are to take the measurement from the inside bead of one side to the other. Now the question my tractor has 4.80x4.00x8 tires and they are mounted on IH rims that measure 8 inches by 2.5 inches wide. ( inside bead to inside bead). The measurement from the outside rim to the other side is 3 inches. All reading material I have seen references rims for this size tire measure 3.75 x 8. Can anyone shed any light on the 2.5 inch rims? They were original to the tractor when my father bought it in 1967.
Thanks
