A tubeless tyre is like the traditional tyre but without a tube. An airtight seal between the tyre and the rim holds the air inside the wheel. Tubeless tyres run under low pressure, and they are less prone to punctures as the tube will not be in between the side and the tyre.
However, tubeless tyres also get punctured. The downside of it is that puncture repairs will often need special equipment that the driver might not have on hand.
Additionally, trying to repair the puncture yourself can damage it further, rendering the tyre irreparable. Having said that, below are some common methods used to repair tubeless tyres.
1. Plug method
In this method, the mechanic uses a hand drill to clear the hole. They then insert a plug system inside and use an adhesive to secure it. After that, they use a blade to trim the excess parts of the plug. The result is a secure and permanent repair.
2. Filler method
Here, professional use a probe to displace steel cords and make it easier to apply a repair compound. The probe does nothing to increase the size of the hole.
After that, they place the compound for repair inside using a wrench. It naturally bonds with the tyre, although the repairman could also use an adhesive.
3. Patch method
In the case of the patching method, the professional files the damaged area. They then use a pre-made patch, depending on the size of the damage, to fix it using an adhesive. This method is best as a temporary solution.
Each one of the methods has its pros and cons. For instance, the filler method results in the formation of stiff ridges inside the tyre. These ridges may render it useless should you ever decide to use tubes. As a rule of thumb, ask your consultant to recommend the best option for your situation and budget.
