Direction of rotation
Unidirectional tires offer added
advantages, such as better hydroplaning
performance. To benefit, however, you must
make sure the tires rotate in the direction
An arrow on the sidewall indicates the
intended direction of rotation (spinning)
of the tire.
Tire care and maintenance
Regularly check the tires for damage.
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle.
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
Check the tire inflation pressure at least
once a month. For more information on
checking tire inflation pressure, see
"Recommended tire inflation pressure"
Every time you check the tire inflation
pressure, you should also inspect your
tires for the following
excessive treadwear (
cord or fabric showing through the tire's
bumps, bulges, cuts, cracks or splits in

Replace the tire if you find any of the above
Life of tire
Tires should be replaced after 6 years,
regardless of the remaining tread.
The service life of a tire is dependent upon
varying factors including but not limited
Although the applicable federal motor
vehicle safety laws consider a tire to be
worn when the treadwear indicators (TWI)
become visible at approximately

your tires to wear down to that level. As
