MOTORCYCLE TIRE SAFETY TIPS
MOTORCYCLE TIRE SAFETY INFORMATION
|
|
Any tire, no matter how well constructed, may
fail in use as a result of punctures, impact damage, improper inflation,
overloading, or other conditions resulting from use or misuse. Tire
failure may create a risk of property damage, serious personal injury
or death. To reduce the risk of tire failure, we strongly recommend
you read and follow all safety information contained in this brochure.
Bridgestone/Firestone recommends periodic inspection
and removal of any imbedded objects by a qualified service person.
Serious personal injury or death may result from a tire failure.
Many tire failures are preceded by vibration, bumps, bulges or irregular
wear. If a vibration occurs while riding your motorcycle, or you
notice a bump, bulge or irregular wear, have your tires and motorcycle
evaluated by a qualified service person.
It is not often that a properly maintained
tire will "blow out" while you are riding. More commonly
if air is lost, it will be gradual. If you do experience a blow
out or sudden tire failure, the following information should be
helpful: When the failure occurs, slowly decrease the amount of
throttle, hold the handlebars firmly, and steer to maintain your
lane position. Once the motorcycle has slowed and is fully under
control, apply the brakes gently. Gradually pull over to the shoulder
and come to a stop.

TIPS FOR SAFE TIRE INFLATION
|
- Check your tire air pressure at least once a month and before
long trips. Be sure to use an accurate pressure gauge.
- Check your air pressure when the tires are "cold."
The tires are "cold" when your motorcycle has been ridden
less than a mile at moderate speed or after being stopped for
three or more hours.
- If you must add air when your tires are hot, add four pounds
per square inch (4 psi)(28 kPa) above the recommended cold inflation
pressure. Recheck the inflation pressure when the tire is cold.
- Never release air from a hot tire in order to reach the recommended
cold tire pressure. Normal riding causes tires to run hotter and
inflation pressure to increase. If you release air when your tires
are hot, you may dangerously under inflate your tires.
- If your tires lose more than two pounds per square inch (2 psi)(14
kPa) per month, the tire, the valve, or wheel may be damaged.
Consult your local dealer for an inspection.
- Use valve caps to keep valve cores clean, clear of debris and
to help guard against air leakage.
|
| Riding
your motorcycle in an overloaded condition is dangerous. Overloading
causes excessive heat to build up in your tires. This can lead
to sudden tire failure and serious personal injury or death
while the tire is overloaded or at some later date. |
|
- Consult your motorcycle owner's manual for
the motorcycle load limits and proper tire inflation that applies
to your motorcycle and tires.
- Never exceed the maximum load rating stamped
on the tire sidewall of your tire or the maximum vehicle load
rating, whichever is less. Before a trip, determine the total
weight of luggage, equipment, and rider(s) to be added to your
vehicle.
- Never exceed the accessory restrictions and
motorcycle load capacity found in the owner's manual, or the maximum
load molded on the sidewall of the tire.
- Pulling trailers behind your motorcycle is
not recommended by Bridgestone/Firestone as trailers may contribute
to motorcycle instability and overload.
|
| Riding
on damaged tires is dangerous. A damaged tire can suddenly fail
causing serious personal injury or death. Have your tires regularly
inspected by your local dealer for damage. |
|
TIPS FOR SPOTTING DAMAGED TIRES
|
- After striking anything unusual in the roadway,
ask your local dealer to demount the tire and inspect it for damage.
A tire may not have visible signs of damage on the tire surface.
Yet, the tire may suddenly fail without warning, a day, a week,
or even months later.
- Inspect your tires for cuts, cracks, splits
or bruises in the tread and sidewall areas. Bumps or bulges may
indicate a separation within the tire body. Have your tire inspected
by a qualified tire service person. It may be necessary to have
it removed from the wheel for a complete inspection.
- Inspect your tires for adequate tread depth.
When the tire is worn to the built-in indicators at 1/32nd inch
(0.8 millimeters) or less tread groove depth, or the tire cord
or fabric is exposed, the tire is dangerously worn and must be
replaced immediately.
- Inspect your tires for uneven wear. Wear on
one side of the tread or flat spots in the tread may indicate
a problem with the tire or vehicle. Consult your local dealer.
- Inspect your rims also. If you have a
bent or cracked rim, it must be replaced.
|
| Riding
at high speed is dangerous, and can cause a motorcycle accident,
including serious personal injury or death. |
- Regardless of the speed and handling
capabilities of your motorcycle and its tires, a loss of control
can result from exceeding the maximum speed:
(a) allowed by law or (b) warranted by traffic, weather, vehicle,
or road conditions. High-speed riding should be left to trained
professionals operating under controlled conditions.
- No tire, regardless of its design or speed
rating, has unlimited capacity for speed, and a sudden tire failure
can occur if its limits are exceeded.
|
|
Never use race only tires on public roads. Race
tires are constructed in such a way that they are very unstable
under normal street riding conditions. These tires also require
higher operating temperatures for proper performance. These temperatures
cannot be obtained within legal speed limits.
|
| Spinning
a tire to remove a motorcycle stuck in mud, ice, snow, or wet
grass can be dangerous. A tire spinning at a speedometer reading
above 35 miles per hour (55 km/h) can in a matter of seconds
reach a speed capable of disintegrating a tire with explosive
force. Under some conditions, a tire may be spinning at a speed
twice that shown on the speedometer. This could cause serious
personal injury or death to a bystander or passenger and extensive
motorcycle damage. Never spin a tire above a speedometer reading
of 35 mph (55 km/h). |
|
|
Regularly inspect the spokes of your motorcycle
wheels. Broken or loose spokes may cause wheel wobble, which can
lead to instability and premature tire wear.
