Tires

ORV tires take a lot of punishment, so maintaining the correct tire pressure is critical. Most ATVs have relatively small, low-pressure tires. Motorcycle tires may or may not be low-pressure, depending on the model. Consult your owner’s manual for the recommended pressure.

  • Check the tire pressure before each trip. Over- or under-inflated tires:
    • Can result in tire or wheel damage.
    • May change the handling characteristics of your vehicle.
  • For low-pressure tires, use a low-pressure gauge. Most standard automobile tire gauges do not read low pressures accurately.
  • Be sure all tires have the same pressure. Otherwise, vehicles with three or four wheels may pull left or right.
  • Inspect each tire for damage that could cause an air leak.
  • Remember that altitude affects tire pressure. A pressure that reads okay at home will read lower after you take the vehicle into the mountains.

Wheels

  • Check the wheel lug nuts used to secure the wheels to be sure they’re tight.
  • Check for worn-out parts by trying to rock the wheel on its axle.
