Uneven tread wear - This can include more wear on one tread edge than the other, a rippled pattern of high and low wear, or exposed steel wire. L'usure irrégulière peut aussi être causée par des problèmes comme un sous-gonflage, un mauvais alignement du véhicule ou un mauvais équilibrage.

Troublemakers - Check for small stones, pieces of glass, bits of metal and other foreign objects that might be wedged into the tread and carefully remove them. Ils peuvent entraîner de graves problèmes s'ils s'introduisent plus profondément dans le pneu durant la conduite.

Damaged areas - Cracks, cuts, splits, punctures, holes and bulges in the tread or on the sidewalls of the tire can indicate serious problems, and the tire may need to be replaced

Valve caps - Those little caps on your tire's valve stem keep moisture and dirt out, so make sure they are on all your tires. Also, when you have a tire replaced, have a new valve stem assembly installed at the same time
