SAFETY PRECAUTIONS FOR MOUNTING RACING AND COMPETITION TIRES
TIRE MOUNTING IS DANGEROUS AND MUST BE DONE ONLY BY SPECIALLY TRAINED PROFESSIONALS USING PROPER TOOLS AND PROCEDURES. FAILURE TO FOLLOW THESE PRECAUTIONS CAN RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
ALWAYS mount tires only on rims which are undamaged, smooth and clean.
ALWAYS be sure the rim diameter matches the nominal tire diameter. The bead diameter must be exactly the same as the diameter of the rim on which it will be mounted. The beads cannot be forced out against rim flanges by using more air pressure because this will break the beads, and the tire will explode with force sufficient to cause serious injury or death.
ALWAYS be sure both beads and rim flanges are adequately lubricated with an approved mounting lubricant. A "solid" soap is recommended to prevent moisture entering the inside surfaces of the tire.
NEVER force the bead(s) over the rim flange or use sharp-edged or improper tools that could damage the bead(s) or other parts of the tire. When passing tire beads over the rim flange, ensure as much as possible of the bead already over the rim flange is sitting in the wheel well.
ALWAYS inflate tires in a safety cage or with another restraint device.
ALWAYS inflate the tire without the valve core inserted into the valve stem. Inflation air should be as dry as possible.
ALWAYS use a clip-on chuck connected to an extension hose attached to a hand air pressure regulator incorporating a pressure gauge, when inflating and/or seating beads. NEVER use a clip-on chuck connected directly to an air supply when inflating and/or seating beads.
NEVER stand next to or lean over the tire and rim while inflating.
NEVER inflate beyond 40 psi to seat the beads.
ALWAYS after seating the beads, insert the valve core (strong spring-type) and adjust operating inflation pressure. Conditions affecting inflation pressure vary from circuit to circuit. Cooper Tire & Rubber Company Europe Sales Engineers can offer guidance on optimum performance inflation pressures. Tires must always hold enough inflation pressure to avoid distortion or rolling under during cornering.
Cooper Tire & Rubber Company Europe does not recommend using tire pressure regulating valves, because they can lead to under-inflated tire operation and sudden tire destruction.
NEVER apply direct heat or perform "hot work" on any wheel fitted with an inflated tire, because explosions can occur. Tires inflated with nitrogen do not make hot work safe.
ONLY specially trained Cooper Tire & Rubber Company Europe-approved personnel can hand-cut tire patterns.
NEVER modify any portion of a Cooper® racing or competition tire, for example, by chemically treating the tread compound ("soaking" or "softening" the tread). Any modification could result in premature or catastrophic tire failure with personal injury or death the result.
