Good
The way you drive has a great deal to do with your tire mileage and safety. So cultivate good driving habits for your own benefit.

  • Observe posted speed limits.
  • Avoid fast starts, stops and turns.
  • Avoid potholes and objects on the road.
  • Do not run over curbs or hit the tire against the curb when parking.

When
The forces created by a rapidly spinning tire can cause an explosion by literally tearing the tire apart. These forces impact the whole tire structure and can rupture the entire casing. Some vehicles are capable of bringing a tire to this failing point in 3 to 5 seconds.

When stuck on ice, snow, mud or wet grass, the vehicle should be rocked gently back and forth by repeatedly shifting the gear lever from drive to reverse on automatic transmissions, or reverse to second on manual transmissions. This should be done with the least amount of wheel spinning. If that doesn't free the vehicle, get a tow.


Highway
No matter how carefully you drive, there is always a possibility that you may eventually have a puncture and wind up with a flat on the highway. Drive slowly to the closest safe area out of traffic. This may further damage the flat tire, but your safety is more important.

Follow the vehicle manufacturer's instructions for jacking up the vehicle, taking off the wheel and putting on the spare. Then drive to a place where the flat tire can be inspected for possible repair or replacement.

Warning!

WARNING!

Avoid tire spinning. Never exceed the 35 mph point indicated on the speedometer. Do not allow anyone to stand near or directly ahead or behind the spinning tire.

After a tire has received a severe impact, such as hitting a curb or pothole, you must have it removed from the wheel and inspected both inside and out for impact damage.

An impact-damaged tire may appear serviceable on the outside, but can fail later after the road hazard injury.


Warning!

WARNING!

Tire explosions can cause death, personal injury or property damage.

Excessive speed in a free-running tire can cause it to "explode" from extreme centrifugal force.


Spare
Many late-model vehicles are equipped with temporary spare tires and wheels which are different from your regular tires and wheels. Some may require higher inflation pressure, or the use of special canisters to inflate the tire.

You may operate a vehicle with such a tire within the limits indicated on the tire's sidewall, until it is convenient to repair the disabled tire or replace it with one of the same size designation and construction as the other tires on the vehicle.

Consult your vehicle owner's manual and the tire sidewall for instructions on proper use of a temporary spare.

Always check the inflation in your spare tire every time you check all the others. A spare tire with no air in it is no help to you in an emergency. If you have an inflatable spare, be sure to check the aerosol air inflation pressure canister to be sure it has not been damaged. If so, have it checked by an expert.

Remember, improper mounting and overinflation may damage the tire or wheel and can result in an explosion that could cause serious injury and death. See safety warning.


Aerosol
Do not depend on tire aerosol sealants and inflators to fix a damaged tire permanently. These products are designed to provide only a temporary, emergency repair to help get you off the road and to the nearest tire repair facility.

Some aerosol products of this type use flammable gases, such as butane, propane or isobutane, as propellants. Follow all directions and precautions printed on the canister when using these products. Be sure to inform tire service personnel that you have used a flammable aerosol to inflate your tire.


Tire Stress

The worse tire stresses occur during hard cornering, fast starts, fast stops.
