FOUR WHEEL DRIVE TIRE COMBINATIONS
The tires fitted to machines with optional four wheel drive have been carefully selected to match the gearing of
the transmission and axles. When renewing worn or damaged tires, always install tires of the same make, model
and size as those removed. The installation of other tire combinations may result in excessive tire wear, loss
of usable power or severe damage to drive line components. If in doubt, consult your Dealer.
