Since each tyre on your car typically supports a different amount of weight, and your driving patterns will typically wear out one tyre faster than the others, it’s important to rotate your tyres between every 7000-10,000 kms. Rotation patterns differ depending on what kind of vehicle you drive. The best place to check is in your vehicle’s owner manual.
Of course, if your vehicle has different sizes of tyres from front to back, or if your tyres are directional, these may not work. Consult vehicle manufacturer’s manual.
Vehicle alignment is one of the most important factors in not only vehicle care, but tyre care as well. Improper alignment on either the front or rear axle can result in unusual tread wear, damage to your suspension, and unusual handling for the car. Wheel alignments should be performed every time you install a new set of tyres, and any time you experience an impact such as a large pot hole, kerb or any other obstacle. For maintenance purpose, alignment should be checked every 10,000 kms.
There are several alignment types, including both two and four wheel alignment. Four wheel alignment is always recommended, but some vehicles cannot have the rear alignment adjusted. Consult with an alignment specialist you trust to find out what’s best for your car.
Mounting and balancing
When mounting wheels & tyres on to the vehicle, ensure the following checks are made:
- Wheels are not damaged in any way
- There is no dirt or oily build up between the hub and the wheel
- Lugs are properly torqued
- Both tyre beads are securely mounted
- Any retaining clips on the brake drums are removed
Tyres are manufactured to close tolerances, however as they wear, their mass can become unevenly distributed, negatively effecting the original balance. The most common signs of unbalanced tyres are vibration problems. These can affect the speed, handling and mileage of your vehicle. Balancing is done by a computer that spins the wheel/tyre assembly, senses heavy spots, and gives a location for the technician to apply weight to counter the heavy spots. The best type of balance is a dynamic balance, and this should be performed whenever possible. Some rim designs however, will not allow this type of balance and you would have to settle for a static balance.
Other mechanical irregularities
- Bent axle
- Loose bearing/wheel shake
- Improperly adjusted, hard/weak suspension
- Loose/ missing wheel stud/nuts
These may have direct or indirect effects on the steering geometry of the vehicle and are likely to cause uneven/fast tread wear.
