TYRE MAINTENANCE TIPS

Proper inflation pressure is necessary for optimum tire performance, safety, and fuel economy. To maintain proper inflation pressure, frequently (at least monthly) check tires (when they are cool) with an accurate tire pressure gauge.

Maintaining proper inflation pressure is the single most important thing you can do to promote tire durability and prolong tread life.

Underinflation is the leading cause of tire failure and may result in severe cracking, component separation, or "blowout." It reduces tire load capacity, allows excessive sidewall flexing, and increases rolling resistance, resulting in heat and mechanical damage. Over inflation increases stiffness, which may deteriorate ride, and generate unwanted vibration. Over inflation also increases the chances of impact damage.

Overloading your vehicle places stress on your tires and other critical vehicle components. Overloading a vehicle can cause poor handling, increased fuel consumption and may cause tire failure. Overloading your tires can result in severe cracking, component separation or "blowout." Never fit your vehicle with new tires that have less load capacity than shown on the vehicle tire placard, and remember that optimum rim width is important for proper tire load distribution and function.

Lack of rotation, worn suspension parts, underinflation, over inflation, wheel imbalance, and misalignment can cause vibration or irregular tire wear. Rotate your tires according to your vehicle manufacturer's recommendations or at maximum intervals of 6,000 mi./10,000 km.

Excessive high speeds results in increased tyre 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 tyre wear and separation of components.

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 tyre wheel assembly are running straight and true.
Proper alignment is necessary for perfect vehicle control, uniform and even tyre wear and safety.
Recommended to get the vehicle alignment checked and corrected as per vehicle owner’s manual as soon as tyre are wearing unevenly or ride handling problems(vibrations, pulling to one side etc).

Out-of-balancetires will cause a car to vibrate at certain speeds, usually between 50 and 70 mph. A tire is out of balance when one section of the tire is heavier than the others. One ounce of imbalance on a front tire is enough to cause a noticeable vibration in the steering wheel at about 60mph. To balance a wheel, the technician will mount it on a balancing machine which spinsthe wheel to locate the heavier part. He will then compensate for the heavy part byattaching a lead weight on the opposite side. Many people are pleasantly surprised at howsmooth their car drives after balancing all four wheels.
Properly balanced tyres are important for driving comfort and long tyre life.
Tyres 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.

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

Vehicle /tyre operating conditions which significantly influence tyre life both in terms of new tyre life and structural durability.

Rough/abbrrasive road surface,
Paved road,
Straight road,
Broken up roads,
Hilly windings roads,
Unmade country roads

Careful driving habits will ensure optimum tyre life, unavoidable damages besides avoiding serious road accidents. Some of the habits which cause serious damages to tyre and road accidents are:

Over 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 tyres

Climatic and whether conditions in our country varies widely from region to region. Dry and extremely hot during summer, extreme cold during winter and rains during monsoon.

This variation in climatic conditions influence tyre life in terms of mileage and structural durability.

Tyre Pressure checks including the spare tyre must be done regularly at least once in two weeks.
Tyre pressure should be checked using an accurate pressure gauge.
Tyre pressure should be checked when tyres are cold.
Under inflation and over inflation will cause rapid tread wear and premature tyre failures.
Tyre pressure should always be maintained as per the vehicle manufacturers recommendations, mentioned at information placard, at door, owners manual.
