Understanding the Risks of Repairing Run-Flat Tires
Why Manufacturers Advise Against Repair
Pirelli and other manufacturers strongly advise against repairing run-flat tires due to the potential risks involved. The reinforced structure of these tires makes it difficult to detect any secondary damage that may have occurred during a puncture. This means that even if the main puncture is repaired, there could be hidden damage that compromises the tire’s integrity, leading to potential safety issues on the road.
British Standard BSAU159 and Tyre Repair
The British Standard BSAU159 outlines specific guidelines for repairing punctures in tires. According to this standard, only punctures located in the central part of the tread (the T area) can be repaired, and the hole must be no larger than 6mm in diameter. However, these guidelines do not apply to run-flat tires, which have unique structural reinforcements that make them unsuitable for repair.
Costco’s Policy on Repairing Pirelli Tires
Some retailers, like Costco, have policies against repairing Pirelli tires, citing the manufacturer’s guidelines. This is because Pirelli does not allow patches in their tires, and the risk of undetected damage is too great. While some independent shops may still repair these tires, it is generally not recommended.
