Inflation Pressure

The science and the technology that has gone into producing even the best quality of tire will go waste if the tires are not inflated to the recommended pressure – Pressure compensating to the load carried. The best performance of tires can only be achieved when the tire is inflated to the designated pressure based on the load per tire.
“Under inflation” or “Over inflation” on the tire tend to impact tire life, vehicle handling and safety. There are two factors with weight distribution of the vehicle. One is contact patch and other linked to the tire wear. This result in heat build-up/tire temperature and thus loss of tire life, premature tire removals, increased rolling resistance and fuel consumption.
“Under Inflation” is more common than Over inflation. Tire users are not always conscious about maintaining or matching tire pressure to the loads carried. In pneumatic tire the “Air carries the load”. The best tire performance and lower tire CPKM are obtained by maintaining correct tire inflation pressure.

Loading

It is important to remember that the total weight (GVW) carried may not exceed the registered laden weight (RLW) or vehicle passing weight, but one side of the truck or one axle may be severely overloaded due to improper distribution of the load in the pay load platform or loading area. Improper load distribution overloads the tire(s). This condition combines with high speed , long hauls and load transfers result in tires wearing fast and premature removal of tires

Speed

Excessive high speeds results in increased tire running temperature. As the rubber gets heated up its modulus (stiffness) gets reduced. Rubber being a good non conductor of heat the residual heat is retained causing increased tire wear and separation of components.

Wheel Alignment

A vehicle is said to be properly align when all the steering and suspension components and set as per the vehicle manufacturer and when the tire wheel assembly are running straight and true.
Proper alignment is necessary for perfect vehicle control, uniform and even tire wear and safety.
Recommended to get the vehicle alignment checked and corrected as per vehicle owner’s manual as soon as tire are wearing unevenly or ride handling problems(vibrations, pulling to one side etc).

Wheel Balancing

A wheel which is not properly balanced may setup vibrations which can affect steering control. Wheels, tires and tubes are usually checked for balance before leaving factory. This balance is achieved by positioning weights on the wheel to counterbalance heavy spots on the tire wheel assembly. Properly balanced tires are important for driving comfort and long tire life. Tires should be balanced when they are mounted on the wheels for the first time or when they are removed for repair or periodically as per vehicle manufacturer’s recommendations.

Tire rotation

Rotation of tire in a vehicle is recommended for a uniform tire tread wear on all wheel position to achieve optimum tire life. It is preferred to rotate tires as per vehicle manufacturers recommendation or in case of any uneven tire wear noticed. It is suggested to check wheel alignment, wheel balance and suspension before the tires are rotated. Rotation patterns /pictures to be incorporated.

Road Conditions

Vehicle /tire operating conditions which significantly influence tire life both in terms of new tire life and structural durability.
Rough/abrasive road surface
Paved road
Straight road
Broken up roads
Hilly windings roads
Unmade country roads

Driving habits

Careful driving habits will ensure optimum tire life, unavoidable damages besides avoiding serious road accidents. Some of the habits which cause serious damages to tire and road accidents are:
Speeding
Speeding over pot holes, stone etc.
Quick starts and sudden stops
Riding over road divider and other obstacles
Sharp turns at high speeds
Hitting the road, curbs, objects etc.
Running on improperly inflated tires
Do’s & Don’ts
Tire Pressure checks including the spare tire must be done regularly at least once in two weeks.
Tire pressure should be checked using an accurate pressure gauge.
Tire pressure should be checked when tires are cold.
Under inflation and over inflation will cause rapid tread wear and premature tire failures.
Tire pressure should always be maintained as per the vehicle manufacturers recommendations, mentioned at information placard, at door, owners manual.
