Tyre Rotation

Front and rear tyres wear at different rates, because they have different jobs. Depending on the make of your car, then either the front wheels supply the power, or the rear wheels. Sometimes, all the wheels have power at all times. The front wheels have the job of turning to steer, while the rear tyres are just along for the ride. It’s differences like these that wear your tyres unevenly.

Other factors in uneven wear are loading, suspension, and steering. The heavy engine at the front puts a different load on the front tyres than the often empty rear. Your suspension can make a difference to the wear of your tyre too. The suspension, being what keeps your wheels firm on the ground, are often times putting uneven pressure on each of the wheels.

For these reasons, and more, you need to rotate your vehicle’s tyres about every 10,000 km; sometimes sooner depending on the vehicle manufacturer.

If you notice uneven wear then it is time to get a professional to check the wheel alignment and balance, as well as a rotation.

Rotating tyres is a pretty easy job that you can do at home with the right equipment. There’s no need for specialty equipment like sensors and measuring instruments. A good quality hydraulic jack and some jack stands are all you need in addition to the tools that come with your spare tyre.

Points to Watch Out For

If you are doing it yourself, then be cautious of a few things.

Unidirectional tyres can only be rotated one way. You’ll see the direction of travel marked with an arrow on the sidewall of the tyre. Usually unidirectional tyres have a particular direction because of asymmetrical tread patterns. Some tyres, will have a particular pattern for wet weather driving on one side, and another for grip while cornering on the other side. These patterns have to be in the correct orientation for them to achieve their purpose, so be sure to keep an eye out for the arrows.

Look out for diameter and width. Some vehicles, mostly specialty or sport vehicles, will have tyres with a different diameter or width on the front and back. When this is the case, then the tyres can only be rotated like with like. That is to say, a wide tyre can only be rotated with another wide tyre.

Incorporate the spare wheel for longer life. The next time you are rotating your tyres, or having someone rotate them for you, include the spare tyre in the rotation. This way, you will take one tyre from your four driving tyres, and replace it with your spare. Then the other tyres are rotated as usual.

Why Rotate?

Rotation maximises tyre tread life, this helps keep you and your loved ones safe while driving. Of course, the longer your tyres last, the more money you’ll save.

Tyre rotation also helps to reduce road noise and vibrations. This means greater ride comfort, especially on long journeys.

Particularly for 4×4 and all wheel drive vehicles, tyres must be rotated to preserve the life of the drive train. Tyres that wear unevenly can cause undue stress while your vehicle’s drivetrain is continuously compensating for the difference in friction against the road. More important is that uneven wear of one tyre might mean that it becomes a different diameter to the other tyres. The difference in diameter mean that it wants to travel at a different speed to the other tyres. For all wheel drive systems, it is critical that all the tyres travel at the same speed.

What Next?

You’re probably like most people, and have little time or motivation to rotate your tyres yourself. So call Goondiwindi Tyre Service on 07 4671 2577 and book in a rotation today.
