Can a 2cm cut in the tire be repaired?
2 Answers
A 2cm cut in the tire cannot be repaired and requires tire replacement. The rubber on the sidewall of the tire is very thin and prone to blowouts at the damaged area, making it unrepairable. Repairing would involve grinding away part of the rubber, making it even thinner. Most repair shops do not repair tire sidewalls and recommend replacement instead, as safety comes first. The following tire conditions indicate that the tire should not be used further: If the tire is worn out: Tires have tread wear indicators, which are slightly raised marks located at the bottom of the tread grooves with a height of 1.6 mm (the legal minimum groove depth). If the tread rubber blocks wear down to the same height as these raised indicators, the tire should be replaced immediately, as continued driving is no longer safe.
A few days ago, I found a big cut on my car tire, about 2 cm long, so I immediately went to the repair shop to ask the mechanic. The mechanic said such a long cut definitely couldn’t be patched—the tire damage was too severe, and even if it were patched, it wouldn’t be safe. At first, I hesitated because I didn’t want to spend money on a new tire, but the mechanic explained that damage to the sidewall is the most dangerous, as it can easily lead to a blowout at high speeds. In the end, I gritted my teeth and replaced the tire. The mechanic also showed me the internal structure of the tire and said that cuts longer than 1 cm generally require replacement. For safety’s sake, it’s better not to skimp on this expense, and we should also be careful to avoid road debris while driving.
