Can a punctured Mercedes tire be repaired?
1 Answers
Mercedes' run-flat tires can be repaired if punctured by a nail, but compared to regular tires, run-flat tires are more difficult to repair. Once the damage exceeds their tolerable limit, even if you manage to drive to a repair shop, the tire will likely need replacement. Some brands recommend replacing run-flat tires if they are punctured and lose air, while others suggest replacement if the puncture diameter exceeds 6mm. Currently, there are several main types of tire repair methods: 1. Patch repair: A rubber patch is applied to the inner wall of the tread to cover the puncture. Some patches require heating, commonly known as "hot patching"; others use adhesive directly, called "cold patching." 2. Plug repair: A rubber plug is inserted into the tread to seal the puncture hole and prevent air leakage. Plugs range from simple rubber plugs to more complex "mushroom plugs," with the latter being the most effective. 3. Inflator with sealant: Sealant is injected into the tire through inflation, and it automatically forms an airtight film over the puncture to seal the hole.
