Looking to buy a set of rims (with or without tires) for 2012 Cub Cadet/Yanmar Sc2450 (backhoe). Tire sizes are 18 x 8.50 -10 (front) and 26 x 12.00 -12 (rear). The bolt hole patterns and sizes are identical on both front and rear rims with a 3 1/8" diameter hole for the hub and 7/16"+ diameter wheel bolt holes (5 holes) to accommodate the 7/16" mounting bolts. There are a number of manufacturer part numbers that identify the rims and tires as an assembly (or kit), depending on the type of tires (turf, industrial, or agricultural). The rims also have their own unique part number.
