electric generators/motors, hot pipes, etc., and tires should never be allowed to stand or come
into contact with water, grease, fuels, brake fluid or any other chemicals.
If tires are stored on a vehicle during an extended period of non-use, it is important to maintain
proper tire pressure, and move the vehicle so that different positions on the tires are in contact
with the ground over time rather than the same position consistently being in contact with the
ground.
If sensorized tires are stored off the vehicle during seasonal changes, the fitted unit must be
stored in a stack, inflated at a maximum pressure of 1.5 bar (21.75 psi) to preserve the sensor
battery life.
Warning: It is essential to inflate sensorized tires to placard pressure before returning
tires to service.
If you need to transport your tires, please follow the above guidelines.
WARNING: Driving on an improperly stored tire is dangerous, as the tire can suddenly
fail, which can lead to an accident and serious personal injury or death.
17. Tubes in Tubeless Tires
Under no circumstances are tubes to be used in Pirelli tires marked “Tubeless”. This includes
tires that have been repaired. If the tire’s pressure retention ability has been affected, so as to
necessitate a tube being installed, the tire must be replaced.
18. Tire Valves
Whenever new tires are installed on your wheels, new tire valves of the correct type must be
installed. It is important that TPMS functionality be confirmed at the time a new tire is installed.
During your routine tire inspection, verify that all your valves have proper valve caps.
Replace as necessary, since the valve cap is also a seal against pressure loss.
19. Tire Dismounting and Mounting
Tire fitting should be left to professionals who have the equipment and training to perform the
task properly and safely using U.S. Tire Manufacturers Association and The Tire and Rubber
Association of Canada procedures or the vehicle manufacturer’s recommendations. To
maximize the performance of your tires, they must be installed following the tire sidewall
markings with respect to direction of rotation (directional arrow) or the proper side facing outside
(Outside/Inside). If there is no arrow or “Outer” or “Inner” designation inscribed on the sidewall,
mount the tire with the full (12 or 13 digit) Department Of Transportation (DOT), tire identification
information facing out. Your wheels should be in good, clean condition. Wheels should be
inspected for distortion, dents, cracks, rust and foreign matter, and be replaced as necessary.
NEVER EXCEED 40 PSI WHEN SEATING BEADS. Both beads and wheels must be clean,
undamaged and well lubricated prior to bead seating. Sensorized tires require special care in
mounting and demounting to avoid damage to or detachment of the sensor.
