Quick facts: Tires that are beyond repair
- The tread depth is less than the legal limit of 1.6mm.
- Rubber is worn or cracked.
- If the puncture’s diameter is greater than 6mm
- If the puncture is not located in the tread area or the sidewall.
- Tires have suffered structural damage or flat damage.
- Continental will never recommend that you repair your tire, but instead replace it.
So you have punctured one or more tires. It could happen. It can happen.
Most countries have a strict law that defines the repair materials and allows for the maximum number of repairs per tire. These regulations are essential to ensure safety for all road users.
Tire repair is not permitted when:
- The tread depth is lower than the 1.6 mm legal limit;
- Tires with run-flat damage or structural problems have been damaged.
- Rubber is worn or cracked.
- An external object causes damage.
- The cords are exposed
- Any traces of past faulty repairs are not evident.
It is important to determine the exact location of punctures. According to the rules, tire repairs must be done within the central three-quarters (or “minor repair zone”) of the tread.
A repair is not permitted if the puncture’s diameter is greater than 6 mm. The only option for drivers is to buy a new tire.
Is it possible to repair punctures in the sidewall?
No. Because it is so close to the sidewall, a puncture outside of the minor repair area will not be eligible for repair.
For a simple reason, the sidewall is not allowed. This section is subject to a lot of stress when the tire is used daily. Repairs made in this area could lead to tire structural weakness.
The tire’s sidewall is the one that experiences the most flex. The tire will eventually fail again if a patch is applied to this area.
If you want to save a flat tire, you need to stop driving on it. The tire’s shape is maintained by the inflation pressure. If that pressure is lost, the tire’s sidewall will be caught between the wheel rim of the road and the tire.
Continuing to drive on a flat tire will only cause minor damage.
Also, don’t drive with a punctured tire that is not within the repair area. Additional damage to the tire sidewall may cause it to be unrepairable. It is better to either have your vehicle towed or swap out the punctured for a spare until you get to a garage.
