It is not uncommon that as your car gets older, or you use it more, later sets of tyres will wear out more quickly. The reason for this is that the every day wear and tear on your vehicles ball joints, CV joints, alignment and your suspension causes more friction on your tyres as they are no longer optimally set up. There is likely nothing wrong with your car, as this naturally happens over time. However, if you are noticing a notable difference, you may want to get your car checked by a garage, or give us a call to check your wheels and tyres.
