TIRES AND WHEELS
Properly inflated tire (2, Figure 155) is an important factor in
determining tire performance and tire life. A tire that is under
inflated (1, Figure 155) does not properly support machine, and
will wear out quickly. Overinflated tires (3, Figure 155) have poor
traction and puncture easily.
Use a pressure gauge to measure tire pressure. Always
measure tire pressure before machine has been working, when
tires are cold. Use table below to determine correct pressure for
front or rear tires when driving machine, or when working
machine.
Check tires for damage and embedded objects. Check valve
stems for damage.
