There are some little tricks to reducing the speed at which your tyres wear.
The main thing is to ensure that your vehicle is well maintained. Part of this is checking your tyre pressure regularly. Also, make sure you always have a good tyre alignment and balancing. It's important that you don't feel any vibrations in the steering wheel or notice any irregular wear on your tyres. A quick monthly visual check allows you to make sure that your car has no alignment problems.
Your driving style influences the wear speed of your tyres. Sudden acceleration and braking, and taking roundabouts too quickly contribute to the premature wear of your tyres.
Finally, remember to use the right tyres at the right time. A summer tyre is not suitable for temperatures under 7°C, and vice-versa, a winter tyre is not suitable for driving above 7°C.
