It a good question, and depends on the wear and tear you have sustained while driving. We are happy to inspect your tyres and advise when you come in to have your
alloys refurbished. However, there are a few things to keep in mind to ensure your tyres are safe and legal which can help as an indicator to when you might need them replacing.
You might notice your car does not perform as well in wet weather or that grip on the road is reduced, so if it takes you longer to stop when braking you might need new tyres. Tyre wear is gradual, so ideally we would recommend you check your tyres monthly. Simply insert a 20p coin into the tread grooves of your tyre at three different places and if you can see the outer rim of the 20p then they could well be lower than the legal limit of 1.6mm. Many tyres now include Tread Wear Indicators (TWI's) in the groves which help identify when your tyre tread is getting low.
Diamond Alloys recommends that you replace all 4 tyres at the same time. However, if you have just one badly word tyre this can be replaced on its own, although we would recommend replacing as a pair is to maintain excellent handling and grip on the axle.
