Proper inflation is the key to tire life and performance. Avoid under-inflation. Tires that are under-inflated wear sooner and demonstrate poor handling. Under-inflated tires generate more heat due to excessive flexing which can ultimately lead to tire failure. Always check the air pressure when the tire is cold. Check the air pressure of your tires on a regular basis. When in doubt, always check the tire manufacturer's recommended air pressure that is engraved in the sidewall of the tire.
Inspect your tires on a regular basis. Check both the sidewall and tread areas for cuts, abrasions or cracks. When inspecting the tread, also look for signs of abnormal tread wear. Abnormal wear can indicate misalignment or imbalance due to developing suspension problems. Replace old tires. When a tire ages, it becomes hard. Tires that are dry and hard have a tendency to skid on slick surfaces providing little or no stopping ability.
When replacing tires, always equip them with new tubes. In the case of tubeless tires, new tubeless valves should be installed in the rim.
Never mix tires of different size or construction on the same axle. Avoid mixing radial and bias-ply tires on the same vehicle.
When purchasing whitewall tires, keep them wrapped and protected until you are ready to have them mounted. If storage is necessary, keep them in a cool, dry area and laid flat. Store them away from sunlight or electric motors. Remember that ozone kills rubber! Absolutely never lean the whitewall side of a tire against the black sidewall of another tire. If this occurs, permanent brown stains will appear in the whitewall.
Clean as often as necessary and on a regular basis. Use only top quality name-brand cleaners when cleaning whitewall tires.
