Natural rubber is not black. In fact, it’s closer to white and the same goes for the rubber used for tyres. However, during the manufacturing process, a filler called 'carbon black' is added to make the tyres tougher and more resistant to temperature changes and abrasive surfaces, which causes the tyre to appear black. Carbon black also helps the tyre roll easier which helps the cars driving performance and fuel consumption.
You can get new tyres fitted at specialist tyre retail chains and independent tyre retailers. Most mechanical workshop businesses also offer tyre fitment services. Mobile tyre fitment is also an option.
Many manufacturers recommend that tyres be replaced 10 years from their date of manufacture, even if the tread on the tyres still looks good. Even if tyres have not been used, the rubber can still degrade by being exposed to the elements. A 4-digit number on your tyres will let you know when it was manufactured. For instance, 1017 means the tyre was manufactured in the 10th week of 2017. This tyre would need to be replaced, regardless of tread wear, by the 10th week of 2027.
Tyres are repairable, although this does depend on the damage they have sustained. Some examples of repaired damage;
- Puncture has been caused by something small such as a nail
- The puncture has not gone too deep
- The puncture has a diameter of less than 5mm
- The location of the puncture is in the centre of the tyre (not on the shoulder or sidewall)
Tyres themselves do come with some form of warranty from their manufacturer, although the details can differ between brands. In most cases, the warranty will cover manufacturing defects. Some brands will even offer warranties against accidental damage, however, there are generally terms and conditions that need to be met in order to qualify.
