TIRE SIZE COMBINATIONS-MFD
Your MFD Tractor must use front and rear tire combinations that are
correctly matched. The use of recommended tire combinations will give
maximum tractor performance, extended tire and reduced wear on
drive train components.
IMPORTANT: The tire size combinations shown below are specified to
provide matched ground speeds of the front and rear tires. Mixing worn
and new tires or tires of different diameters or loaded radii can give incorrect
ground speed match. When replacing tires, consult your Dealer.
