Hors Route Proper Inflation
Une vérification mensuelle de vos Yokohama s’impose. Pas uniquement parce qu’ils ont belle allure. Mais pour vérifier si les flancs n’ont pas subi de coupures ou d’accrocs, et qu’il n’y a pas de clous ni de vis qui s’y sont logés.
Aussi devriez-vous en vérifier l’état d’usure de la bande de roulement. Les photos suivantes illustrent une usure inégale ou excessive.
Usure d’un côté
Description
The tread on one shoulder of the tire is wearing faster than the other shoulder. May be present on both tires on the same axle.
Cause
Misalignment (toe or camber), not rotating tires as recommended, aggressive driving style.
Action
Correct alignment condition. Rotate tires as recommended by Yokohama. Reversing the tire on the wheel may extend tire life (take care with unidirectional or asymmetric tires). Moderate driving style.

Both Shoulder Wear
Description
The tread on both shoulders of the tire are wearing faster than the tread elements in the center of the tire.
Cause
Improper inflation pressure, not rotating tires as recommended.
Action
Maintain appropriate inflation pressures. Rotate tires as recommended by Yokohama.

usure en creux
Description
Local, irregular worn patches around a tire. May be accompanied by tire noise or vibration.

Action
Rotate tires as recommended by Yokohama. Maintain proper inflation pressure. Verify good mechanical condition of vehicle.

Usure rapide
Description
Tires worn out sooner than expected, with even wear.
Cause
Aggressive driving style, not rotating tires as recommended. Other contributing factors include: driving on abrasive road surfaces, driving in mountainous/hilly terrain, or carrying very high loads. High-performance tires may exhibit this condition more commonly than all-season tires.
Action
Moderate driving habits and avoid spinouts. Rotate tires as recommended by Yokohama. Choose tires with appropriate speed and load rating for the vehicle.

Usure en biseau des barrettes
Description
Tread elements are taller on the front edge than the back edge. May be accompanied by tire noise or vibration. Aggressive tread patterns may be more susceptible to this condition.
Cause
Not rotating tires as recommended. Other causes include: improper inflation and mismatched air pressures on dual tire assemblies.
Action
Rotate tires as recommended by Yokohama. Maintain proper inflation pressure. If not severe, reversing the direction of rotation (for non-directional tires) may extend tire life.
