Tyre Maintenance

Tyre care and maintenance is very important in order to obtain maximum performance, life and fuel efficiency. Following checks are recommended to attain the same :

Maintain Proper Air Pressure :

Inflate the tyres to the recommended air pressure. Check one of the following places to know the proper air pressure for your tyres :
  • In the owner's manual.
  • On the car’s door jamb.
  • Inside the fuel filler flap.     
  • But not on the tyre. The inflation pressure shown on the tyre sidewall is only the maximum tyre inflation pressure.
Compressed Air :

Air tends to expand when it is hot and contract when it is cold.
It is best to check your tyre pressure in the morning before the day’s heat.

Nitrogen :

Nitrogen can also be used to inflate the tyres as it doesn't react to differences in outside temperature or leak out over time as air does.

Tyre Rotation :
 

Regular rotation helps extend the life of the tyres hence saving time and money in the long run. For rotation, each tyre and wheel is removed from the car and moved to a different position. This ensures that all of the tyres wear evenly and last longer. If no period is specified in the owners manual, tyres should be rotated every 5000 to 7000 kms. The spare tyre should be included in the rotation process.

Spare --> Front right --> Front left --> Rear Left --> Rear right --> Spare

Note : Front tyres tend to wear out quickly as they are in-charge for braking, turning and carry the engine weight.

Wheel Alignment :

Proper alignment helps ensure that the car handles correctly and will help increase the life and performance of the tyres. Daily impacts such as potholes and bumps as well as more severe circumstances like accidents, can knock the car out of alignment. Wheel alignment should be checked when the car hits something, a difference in handling is noticed or a wear pattern appears at the edge of the tyres

Wheel Balancing :

At the first sign of vibration or irregular tread wear, your tyres should be checked for wheel balancing and alignment. A wheel is out of balance when one area is heavier or lighter than the rest. An imbalanced wheel can cause off-center tread wear and vibration. Wheel balancing should be done everytime a puncture is fixed, in case a tyre is replaced and also during the tyre rotation process.

Terms :
Tread - The portion of a tyre that comes into contact with the road and can be distinguished by the grooves.
PSI - Pounds per Square Inch
