Tire Mounting Safety Instruction

These instructions are not a substitute for professional training or comprehensive service procedures and are intended for informational purposes only.

For your personal safety and the safety of others:

General Aspects:

• Tires must match the width and diameter requirements of the rims and be approved as a combination for the vehicle model concerned. Always ensure, that Motorcycle and Scooter tires are only mounted on designated motorcycle tire rims, not on any other kind of rim (e.g. passenger car rims).
• Only rims of the correct size in good, clean condition and free of rust or corrosion should be used. They must not be damaged, out of shape or worn.
• Tires must be free of damage and the inside of the tire must be free from foreign material.
• If the tire has a direction arrow on the sidewall, this must be observed.
• When fitting new tires with tube, always use new tubes. As tubes stretch in service, there is a risk of folds forming in old tubes, so re-used tubes could suddenly tear.
• Never mount tires with tubes on rims designed for tubeless tires, i.e. rims that have safety humps or ledges. The rim surface/shape may damage the tube.
• For safety reasons, tubeless tires should always be fitted with new valves.
• If a Tire Pressure Monitoring System (TPMS) is used, please refer to manufacturers recommendation whether the sensor must be serviced or renewed while tire exchange.

Tire Dismounting:

• Before a tire is taken off the rim, the valve insert must be unscrewed and removed to ensure remaining pressure is released completely.

Tire Mounting:

• Always coat the tire beads and the rim with a permitted tire fitting lubricant before mounting. Silicone, petroleum or solvent-based lubricants must not be used for this purpose.
• While the tire is being inflated, the rim must remain firmly secured on the mounting machine. If the tire is mounted on a machine that does not have a positive lock-down device to hold the rim, inflation should be done in a safety cage or other restraining device.
• Never put flammable substances in tire/rim assemblies at any time. Never put any flammable substance into a tire/rim assembly and attempt to ignite to seat the beads. This practice is extremely unsafe and may also cause undetected damage to the tire or rim that could result in failure of the tire in service.
• When fitting tubeless tires, care should be taken to ensure that the tire beads coming from the well-base first clear the hump in the rim shoulder. To avoid cracks in the bead core, the “pop” pressure necessary should not exceed 330 kpa (3,3 bar / 48 psi). If the tire does not pop into place even at this pressure, the pressure must be released, the cause identified and eliminated. Then the procedure can be repeated.
• Only when the tire beads are seated correctly on the rim shoulder may the pressure be increased to support best bead seating and optimized fit on the rim flanges. However, this "seating pressure" should never exceed 150% of the nominal tire pressure for maximum load.
• For some countries, different maximum mounting pressure values have been established by the respective local standardization organizations. Please refer to the table below which shows examples for some countries in order to respect local standards (status as of July 2018, no guarantee for completeness, actuality and correctness).

• Once the tire is mounted correctly, adjust the pressure to the operating pressure specified by the vehicle manufacturer.

After mounting:

• It is necessary to break-in new Motorcycle and Scooter tires! During the break-in period (approximately 150km / 100miles), heavy acceleration and braking, high lean angles and especially high-speed riding must be avoided.
• Remove the tire labels before riding.
• Always warm up your tires each time you ride by gently braking, accelerating and turning for the first few km/miles.
