Correct inflation is essential to the tires’ performance, comfort and durability. Riding underinflated tires can lead to premature wear, arrivers- bile damage to the carcass, and possible tire failure. Tire pressure should be checked every two weeks. Check pressure only when tires are cold, because pressure increases with temperature. Never bleed air from a hot tire. Michelin recommends the tire pressure quoted by the motorcycle maniac- truer, except where otherwise stated. Michelin recommends the use of valve caps at all times. Caps help prevent air loss and keep dirt out of the valve mechanism.
