We often forget to replace our tyres on time, so here are a few ways to tell when you need new tyres. You may notice that your vehicle doesn’t grip the road as well as it did when your tyres were new, or that your vehicle feels like it is slipping in the rain or snow. Both of these problems can happen when your tyres need replacing. Another way to see if you need new tyres is to check the depth of the tread. As tyres wear over time, the tread on them wears down. Uneven tread wear can occur due to under or over inflated tyres or a mechanical problem.
