Proper tire pressure and proper tire loading are important factors.
Overloading your tires can lead to tire failure and loss of vehicle control.
Check tire pressure each day before you ride, and be sure the pressure is correct for the vehicle load according to the table below.
Tire pressure should only be checked and adjusted before riding, since riding will heat up the tires and lead to higher inflation pressure readings.
Under-inflated tires make smooth cornering difficult, and can result in rapid tire wear. Over-inflated tires have a smaller amount of tire in contact with the road, which can contribute to skidding and loss of control.
Note
: when you detect drops in tire pressure, check the tire for nails or other punctures, or a damaged wheel rim. Tubeless tires sometimes lose pressure gradually when punctured.
