Puncture Repair

1. The puncture must be within the crown of the tire. (About 2-inches from each sidewall.)

2. The puncture must also be no larger than a pencil thickness. Approximately 3/16-inch or less.

3. If the sidewall has been compromised, (driven on with low pressure) the tire must be replaced.

4. Run Flat Tires can be repaired just like radial tires so long as the integrity of the tire hasn't been compromised. The tire must be removed to inspect for inside damage.



This picture shows the inside of a tire that has been compromised. Notice the bits of rubber compound. Also, you will see a 'Worm' style tire plug. These plugs are not recommended and are considered a temporary fix. In many cases these plugs will still leak air.

 
Here is the outside of the tire that faces the inside of the vehicle. The wear mark on the side wall indicates the tire has been driven on with low pressure, AKA Ran Flat.






This is the same tire. But this is the side facing outward on the vehicle. Most people only look at this part of the tire. As you can see, it looks to be in good condition. As we saw in the previous pictures, we know this tire has been compromised and is unsafe to drive on. This is why you must always inspect the whole tire, inside and outside.  

 

Here is a good example of a tire that is NOT repairable. The nail has punctured the shoulder of the tire. Punctures on the shoulder or sidewall can NOT be repaired. This tire will need to be replaced and can be claimed under "Road Hazard Warranty", if applicable.
