Can Tubeless Tires Be Repaired?
2 Answers
Tubeless tires can be repaired, but the cost is relatively high because repairing them is more complicated. One of the simpler methods is the cold patch repair. If the tire still leaks after a cold patch repair, you can pour tubeless tire sealant through the valve stem. However, this method is prone to failure in hot weather or when exposed to water, and the sealant will evaporate over time and with usage. It is recommended to add sealant periodically, generally every six months. Tubeless tires cannot be repaired under the following circumstances: Puncture holes exceeding 6 mm: If a puncture hole on the sidewall of a tubeless tire exceeds 6 mm, it has already damaged the cord layer, and continued use increases the risk of a blowout. If the sidewall puncture is smaller than 6 mm, it can be repaired, but for safety reasons, a tire with a repaired sidewall is recommended to be used as a spare. Multiple repairs: If a tubeless tire has been repaired multiple times, especially if the same spot has been repaired more than twice, it is not advisable to repair it again. A tire that has undergone multiple repairs loses its original durability and safety. Signs of underinflation: If there are visible signs of driving while underinflated (such as sidewall abrasion or bubbling of the inner liner), the tire is not worth repairing. At this point, the tire structure may already be compromised and should be replaced instead. Tread deformation: If there is bead damage or deformation, tread deformation, rubber corrosion due to chemicals, or damage from driving underinflated, the tire cannot be repaired and must be replaced.
Last time I got a nail in my car tire, which was also a tubeless tire. When I asked at the repair shop, they said it could be patched. The key is where the nail is located. If it's in the wide central part of the tire, a mushroom plug patch will do the trick. However, if it's on the sidewall, that's troublesome. The sidewall is thin, and patching it can easily lead to bulging or even a blowout, which is too dangerous. I spent 80 yuan to patch it that time, and it's been fine ever since. My suggestion is, if you find a puncture, don't rush to pull out the nail. Drive directly to a professional shop and let them handle it—safety first. Also, remember to check tire pressure regularly to maintain tire health and reduce unexpected issues.
