INDICATOR LOCATION MARKS
TREAD WEAR INDICATOR
Your vehicle's tires have wear
indicators molded into the tread.
When the tread wears down to that
point, you will see a 1/2 inch (12.7
mm) wide band running across the
tread. This shows there is less than
1/16 inch (1.6 mm) of tread left on
the tire. A tire that is this worn gives
very little traction on wet roads. You
should replace the tire if you can see
the tread wear indicator in three or
more places around the tire.
Tire Maintenance
In addition to proper inflation,
correct wheel alignment helps to
decrease tire wear. If you find a tire
is worn unevenly, have your dealer
check the wheel alignment.
Have your dealer check the tires if
you feel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed from the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comfort and tire life. For best results,
have the installer perform a dynamic
balance.
Improper wheel weights can damage
your vehicle's aluminum wheels. Use
only Acura wheel weights f or balancing.
Tire Rotation
Front Front
(For Non-directional (For Directional
Tires and Wheels) Tires and Wheels)
To help increase tire life and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the multi-information display. Move
the tires to the positions shown in
the illustration each time they are
rotated. If you purchase directional
tires, rotate only front-to-back.
