CHECK TIRE PRESSURES
Tire Pressure should be checked periodically, and main-
tained at the levels shown in the chart. Note that these
pressures may differ slightly from the “Max Inflation”
stamped on the side-wall of the tires. The pressures
shown provide proper traction, improve cut quality, and
extend tire life.
