Check Tire Pressures
Tire pressure should be checked periodically, and
maintained 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.
