Rotation of tyres is done to ensure that all the tyres on the vehicle will wear evenly. If you drive with all-weather tyres, you are most likely using the same tyres all year round. All-weather tyres can handle most weather conditions and if they are approved for winter use 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. You eliminate the need to change between summer tyres and winter tyres and have to find the optimal timing for a tyre change.
When you have different grip between front axle and rear axle, your vehicle will not behave, as you would expect. It will over- or understeer 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 all tyres have approximately the same tread depth. The change should be done when there is a 2-3 mm difference between the front and rear tyre. The wear should be the same between the left and right side and also within the tyre profile, as what comes to the wear across the profile. If there are some abnormalities with the tyre wear, you should visit a tyre service station to assess what the cause of the problem could be. There are several factors that can cause uneven wear across the tyre profile.
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. The tread depth will also allow you to know when you need to change to a new set of tyres. You should change to a new set of tyres when you reach the 4 mm remaining tread depth.
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 it can add a lot of costs to your daily drive. Having to replace your tyres prematurely and having to stop for fuel more often can get very expensive. It is an easy thing to check. When it comes to electrical and hybrids, the wear tend to be higher and the normal interval of rotation might not be sufficient, so make sure they monitor them more closely when it comes to tyre wear and the need for rotation.
