Vérifiez régulièrement l’état d’usure de vos pneus. Une fois qu’un profil
inégal est établi, il est difficile à corriger même en éliminant la cause
première de l’usure.

STRUCTURE AND CHASSIS
Driving on a tire without the required pressure for the trailer load is dangerous and can
cause premature wear or damage to the tires. This could also cause loss of control of the
trailer and towing vehicle.
An underinflated tire can cause overheating beyond the acceptable limits for the tire
materials, which could result in sudden failure. An underinflated tire can also make
the vehicle hard to handle, increase wear and resistance to sway, as well as reduce
fuel economy.
Check tire wear regularly. When you discover uneven wear, this is hard to
correct even after you eliminate the main cause of the wear.
