Tire Replacement
Honda recommends that you replace tires in sets of four, or in pairs,
front or rear. If you need to replace only one tire, mount the new
tire opposite the tire showing the least amount of wear.
For instance, if the left front tire shows the least amount of wear,
mount the new tire on the front right side.
The original tires on your car have
tread wear indicators to indicate
when they should be replaced. The
indicators appear as bands about
12.7 mm (1/2 in) wide when the tire
tread depth is less than 1.6 mm
(1/16 in). When indicators appear
across t w o or more grooves in a
row, you should replace the tire.
Driving on worn-out tires is very hazardous, and will reduce
braking effectiveness, steering accuracy and traction.
When replacing tires, use only the recommended tire size. Wheel
rim widths and offsets must be those recommended by American
Honda Motor Co., Inc. Contact the Zone Office nearest you as
shown on the inside of the back cover.
Tires and wheels other than those recommended may be unsafe.
Do not mix radial and bias ply tires on the same car.
