CAUTION: Explosive separation of a tire and rim parts can cause serious injury or death.

Always maintain the correct tire pressure. DO NOT inflate tires above the recommended pressure.

Inspect tires and wheels daily. DO NOT operate with low pressure, cuts, bubbles, damaged rims, or missing lug bolts.

Carefully inspect any tire and rim assembly that has been run flat or severely underinflated before reinflating the tire. Damage to the rim and tire may have developed. Call an authorized dealer or a qualified repair service technician to inspect the rim and tire assembly and make necessary repairs.

When inflating tires, use a clip-on chuck and extension hose long enough to allow adequate space to stand to one side and NOT in front of or over the tire assembly. Use a safety cage if available.

NEVER cut or weld on an inflated tire or rim assembly. Heat from welding could cause an increase in pressure and may result in tire explosion.

Do not attempt to mount a tire if you do not have the proper equipment and experience to perform the job. Have it done by an authorized dealer or a qualified repair service.

Check tire pressure with an accurate gauge having 7.0 kPa (0.07 bar) (1 psi) graduations.

  1. Shut off air supply to hose.

  2. Move gauge hand to correct pressure.

  3. Lock air chuck on tire valve.

  4. Turn on air supply. Stand to front or rear of tire when adding air to tire.

NOTE: Tire shipping pressure may not be the same as tire operating pressure. Tire pressures may be changed to suit working condition according to tire manufacturer’s recommendations.
