Tire mounting instructions

Tire mounting can be dangerous and must be done by professionally trained persons using proper tools and procedures.
Your tires should be mounted on wheels of correct size and type and which are in good, clean condition. Wheels that are bent, chipped, rusted (steel wheels) or corroded (alloy wheels) may cause tire damage. The inside of the tire must be free from foreign material. Have your retailer check the wheels before mounting new tires. Mismatched tires and rims can explode during mounting. Also, mismatched tires and rims can result in dangerous tire failure on the road. If a tire is mounted by error on the wrong-sized rim, do not remount it on the proper rim—discard it. It may have been damaged internally (which is not visible externally) by having been dangerously stretched and could fail on the highway.
Old valves may leak. When new tubeless tires are mounted, have new valves of the correct type installed. Tubeless tires must only be mounted on wheels designed for tubeless tires, i.e. wheels that have safety humps or ledges. It is recommended that you have your tires and wheels balanced.
Serious injury may result from explosion of tire/rim assembly due to improper mounting procedures. Follow tire manufacturer’s instructions and match tire diameter to rim diameter. Mount light truck radials on rims approved for radial service. Do not apply bead sealer. This can inhibit bead seating. Lubricate beads and tire rim contact surfaces. Lock assembly on mounting machine or place in safety cage. STAND BACK and never exceed 40 psi to seat beads. Never use a volatile substance or a rubber “donut” (also known as a bead expander or “O-Ring”) to aid bead seating.
Only specially trained persons should mount tires.
When changing tire sizes, always consult the dealer for optimum rim width and carefully check vehicle/tire clearances.
Tires and wheels that are not balanced may cause steering difficulties, a bumpy ride, and irregular tire wear.
