Rotation of tyres is done to ensure that all the tyres on the vehicle will wear evenly. If you drive with SUV All-weather tyres, then you will most likely use the same tyres all year long. All-weather tyres can handle most weather conditions. If they are approved for winter conditions and have the winter approved symbol, the 3PMSF-symbol on the sidewall, they will also be able to give your vehicle good grip on snow and ice.
When you have different grip between the tyres on the front axle and rear axle, your vehicle will not behave, as you would expect. It will over or under steer depending on where you have the best grip. To avoid this happening you will have to rotate the tyres to even out the wear, so that the wear will be approximately the same. The rotation should be done when there is a 2-3 mm difference between the front and rear tyre. The wear should be even between the left and right side. If there is some abnormalities with the tyre wear, you should visit a tyre service station to assess what the cause of the problem is.
When you rotate, you change the right front tyre to the right rear position and the same on the left side. You would expect to do this 1-2 times per year depending on how much you drive. It is quickly done and a tyre service station can have it done in very short time. You just need to check the tread depth to figure out when you will need to do the rotation. Checking tread depth is easy and can be done while you check the tyre pressure.
Inspection of the condition of the tyres should be done at least every month and preferably every time you stop at the petrol station to fill up the SUV. A visual inspection is quickly done, just to assess if there are visual damages to the tyre. Checking the tyre pressure should be done at least monthly. Wrong tyre pressure can impact your safety and affect the fuel consumption. Having to replace your tyres prematurely and having to stop for fuel more often can get expensive. It is an easy thing to check.
