Maintaining a Goodyear Tire
Proper tire inflation is a key ingredient in driving safety & long tire
life. It is wise to check your tire's inflation at least once a month with
an accurate tire pressure gauge. Continuous loss of inflation pressure is an
indication of a possible tire/wheel assembly problem; consult your tire
professional immediately if you encounter this situation. Be sure to check
the pressure while the tires are cold, & have not been used recently. If
you drive even a mile this will cause your tire pressure to increase &
give you an inaccurate reading.
Checking Tire Tread
There are two popular ways for checking to see if there is enough tread on
your tires. All passenger, light truck, & medium commercial tires have
tread wear indicator bars molded into the tread. These bars are located at
the bottoms of the tread grooves in several locations around the tire, &
when the tire is worn to the point where any of them become visibly flush
with the adjacent tread ribs, it is time to replace the tire. Another easy
way to check that your tire has enough tread remaining is to place a penny
in the tread with Lincoln's head upside down & facing you. if you can see
the top of Lincoln's head it is time to replace your tires.
|Wear On Both Edges:
UNDER INFLATION If a tire looks like this, it may
be under inflated. The worst enemy a tire can have is too little inflation
pressure. Under inflation reduces treadlife through increased tread wear on
the outside edges (or shoulders) of the tire. It also generates excessive
heat which reduces tire durability. Finally, it reduces fuel economy through
increased rolling resistance (soft tires makes your vehicle work harder).
Check your tires regularly for proper inflation. Abnormal tire wear may also
be due to misalignment or mechanical problems.
|Wear In Center: OVER
INFLATION When a tire is over inflated, the center
of the tread bears most of the load & wears out faster than the outside
edges. Uneven wear reduces the useful life of a tire. Check your tires
regularly for proper inflation. Abnormal tire wear may also be due to
misalignment or mechanical problems. Goodyear retailers can provide expert
diagnosis & repair.
|Cups or Dips in the
tread: WORN PARTS Cupping (also called dipping or
scalloping) is most common on front tires, though rear tires can cup as
well. It may be a sign that wheels are out of balance or that suspension or
steering system parts are worn out. Many Goodyear retailers can provide
expert diagnosis & repair.
MISALIGNMENT Do the edges of the tread take on a
sawtooth or feathered appearance? This is caused by erratic scrubbing
against the road. The solution is toe-in or toe-out alignment correction.
Proper tread depth is essential for proper tire performance. If you notice a
loss or change in wet traction, you may not have enough tread left on your
tires. Once the tread depth reaches 1/16th of an inch it must be replaced.
Unbalanced tires cause vibration, which can lead to driver fatigue,
premature/irregular tire wear, & unnecessary wear to your vehicle's
suspension. Your tires should be balanced when they are mounted on
wheels for the first time or when they are remounted after repair. Tire
balance should be checked at the first sign of a vibration or shimmy.
A vehicle is properly aligned when all suspension & steering
components are sound s& when the tire & wheel assemblies are running
straight & true. If you notice uneven tread wear this could be due to
a misalignment & must be serviced by a professional.
While many people are capable of rotating their own tires, it is quick
& easy to let a professional do it for you. Your vehicle's owner's
manual will specify the proper rotation pattern & schedule for your
vehicle. If there is no specific schedule specified a good rule of thumb
is to rotate your tires every 6,000 to 8,000 miles.
Tire repairs should be made by a trained tire professional. Proper
repair procedure will include dismounting the tire from the wheel for a
thorough inspection to check for damage, & the use of a patch & plug
to repair any punctures that fall within the limits & guidelines for
