When Should I Replace My Car’s Tyres?

Car tyres are arguably the most important part of your vehicle. Connecting your vehicle to the road, any damage to car tyres could have devastating consequences. 

The safety of you and other road users could be severely compromised if your car tyres become damaged or worn, so you should always keep an eye on their condition and act if you notice any abnormalities. 

However, for some people, it can be hard to know when a tyre replacement is necessary. 

At Kilnhurst Tyres, we provide our customers with an expert tyre fitting service, helping to keep them safe on the road. With this in mind, this month’s blog will take a closer look at the importance of car tyres, and when you should think about having them replaced.

When should I replace my car’s tyres?

It’s important to regularly inspect your car tyres to check for any faults or damage. You should do this at least once a month and every time you embark on a long journey. On average, you should get about 20,000 miles of driving out of your tyres, but there are a few scenarios where tyre replacement will be necessary even before you’ve reached this milestone. 

If you have a puncture

A tyre puncture is a huge safety risk, and needs to be addressed immediately. If you suffer a puncture while out and about, pull over to a safe place, put on your handbrake, switch off the engine and put on your hazard lights and wear a high visibility safety vest if you have one. We always recommend having tyre replacement carried out by a professional.

When tyres are worn down to the legal limit of wear 

The legal tyre tread depth limit is 1.6mm, and if your car tyres are beyond this then they’re no longer roadworthy. It’s a good idea to organise a tyre replacement before it gets to this stage. You can easily check your tyre tread depth with a tread depth gauge, or by doing the 20p test. Simply place a 20p coin in the tyre’s grooves, and if you can see the rim it suggests the tyres may need changing. 

If your tyre has become damaged or you spot uneven wear 

If your car has recently hit a kerb, pothole or experienced any other kind of solid impact, the tyre may have become damaged. If you spot any cuts, deformations or uneven wear, then get in touch with a professional and they’ll be able to advise.      

How to check the age of my tyres? 

While the longevity depends on the number of miles done on your car tyres rather than their age, after five or more years in use you should get them inspected on an annual basis. You can check the age of your car tyres fairly simply. 

The side of the tyre will have the letters DOT, followed by a four-digit code. The first two numbers refer to the week the tyre was manufactured, and the second two link to the year it was manufactured. 

If you see a three-digit code rather than four numbers, it means the tyres were manufactured before 2000 and must be replaced immediately. 

Why is it important to replace car tyres?

As alluded to above, tyre replacement is all about safety. If you’re driving a car with damaged, worn or old tyres, then your vehicle is a hazard and you’re risking your own safety, as well as your passengers and other road users.
