Can a Punctured Tyre Be Repaired?

A tyre puncture is no fun, but the good news is that punctured tyres can often be repaired! In this blog, we will explore when it is possible to repair your tyre. So, keep reading to find out what you can do.

When Can You Repair a Punctured Tyre?

• Small punctures: Punctures up to 6mm in diameter (in the tread area) can often be repaired safely.
• Location matters: The puncture must be in the tread area of the tyre. If the damage is on the sidewall or shoulder, it usually can’t be repaired.
• No significant damage: If the tyre has been driven on while flat or severely underinflated, the inner structure might be compromised, making repairs unsafe. If a tyre has multiple punctures in the tread area, it is also not safe to repair.

How Do You Repair a Tyre Puncture?

You need to have the right tools and expertise to repair a tyre puncture. Usually, a punctured tyre will be repaired by inserting a plug or patch, depending on the type of puncture. A tyre plug is used for small punctures in the tread area. The plug seals the hole and prevents air from leaking. In some cases, you can use a tyre patch, which is used on the inside of the tyre. Always check with an professional if you’re not sure whether a puncture can be repaired safely.

When Should You Replace a Punctured Tyre?

You should replace a punctured tyre if the puncture is too large or in an unsafe area (such as the sidewall).

If your tyre is already heavily worn, repairing a puncture may not ensure the tyre is safe enough to be on the roads. In this case, it's best to arrange a tyre replacement at your closest Merityre branch. If you are uncertain whether your punctured tyre can be repaired or whether you need a new tyre, it’s always best to call or visit your local Merityre branch for advice.

What is the Condition of the Tyre?

• Tread depth: if it's below 1.6mm, replace the tyre. Learn how to check your tread depth here.
• Tyre pressure: Make sure the tyre is properly inflated.
• Visible damage: Look for cuts, cracks or bulges. Find out more about inspecting your tyres for damage.
• Uneven wear: Check for wear patterns that might indicate alignment or suspension issues.
• Age of tyres: Replace tyres that are too old (every 6 to 10 years), even if they look fine. Pop into your local branch for help and advice.
• Vibration or noises: If you notice vibrations that increase with speed or hear strange sounds, have your tyre inspected by a professional.

How to Maintain the Condition of Your Tyre

• Regularly check tyre pressure and adjust as needed.
• Rotate your tyres every 6,000 to 8,000 miles to ensure even wear.
• Get your vehicle aligned and balanced regularly to avoid uneven tyre wear.
• Replace tyres when the tread depth is low or when there is visible damage or age-related degradation.

What Are Run Flat Tyres and Why Would You Need Them?

Run flat tyres are different to standard issue tyres – they have specially reinforced sidewalls. The reinforced sidewalls maintain the structure of the tyre after a puncture, allowing drivers to continue driving for a limited period. Most run flat tyre manufacturers recommend only driving on a burst tyre for 50 miles at 50 mph. Run flat tyres give you plenty of time to get to a garage or back home if you are stuck on the motorway.

Benefits Of Run Flat Tyres

Run flat tyres have several benefits, all associated with safety:

• a strengthened sidewall to keep your car under control when driving on a puncture
• no need to put yourself at risk by changing your tyreon the side of the road
• no need to carry round a spare tyre

Many new cars are not equipped with a spare tyre, but this does not always mean they have run flat tyres! Replace with: To check whether your car has run flats check the tyre sidewall to see if it is marked with RFT (run flat tyre), ROF (run on flat), RSC (run flat system component) or SSR (self-supporting run flat), you can also check your car manual or check online for the manufacturer's specifications for your model. If your vehicle is equipped with a spare tyre or foam filler tyre repair kit it is unlikely that your car tyres are run flats.

Additionally, all vehicles with run flat tyres must be fitted with a tyre pressure monitoring system (TPMS) to ensure the driver is aware when a tyre has been punctured or the tyre pressure decreases due to another reason.

If you are still unsure whether you have run flat tyres, you can always have your tyres checked at your local Merityre garage.

Can Run Flat Tyres Be Repaired?

As the reinforced structure of run flats can mask any secondary damage caused by a puncture, repairs are not recommended.

You’ll know your tyre is flat from your TPMS which should indicate a loss in tyre pressure. If you notice any tyre damage or loss of pressure, head to your closest Merityre branch. (As tyres are usually replaced in pairs avoid recommending a single tyre is replaced).
