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. The inflation reduces tread life 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 and 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. Keister's tire personnel
can provide expert diagnosis and 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. Again, Keister's
service personnel can provide expert diagnosis and repair. |
