Which Area of the Tire Cannot Be Repaired?
2 Answers
The sidewall of the tire cannot be repaired. Below are some precautions for car tires: 1. Pay attention to tire pressure: Pressure is the lifeline of a tire. Both excessive and insufficient pressure will shorten its lifespan. Insufficient pressure increases tire body deformation, leading to cracks on the sidewalls and causing flexing movements, which generate excessive heat, accelerating rubber aging, fabric layer fatigue, and cord breakage. Insufficient pressure also increases the tire's contact area with the ground, accelerating shoulder wear. Excessive pressure overextends the tire cords, reducing the tire body's elasticity and increasing the load on the car during driving. In case of impact, this can cause internal cracks and blowouts. Additionally, excessive pressure accelerates tread wear and reduces puncture resistance. 2. Regularly check front wheel alignment: Front wheel alignment significantly affects tire lifespan, with toe-in and camber being the main factors. Excessive camber mainly accelerates shoulder wear (uneven wear), while incorrect toe-in (either too little or too much) primarily accelerates wear on the inner and outer sides of the tire.
The sidewall of a tire is absolutely not repairable. As an experienced driver with many years behind the wheel, I've encountered several instances of punctures in the tire sidewall and always advised replacing the tire outright rather than attempting a repair. The sidewall is the weakest part of a tire, constantly enduring bending and impact forces—repair adhesives won't hold well or seal properly, posing a high risk of blowouts at highway speeds. Once there's a crack, bulge, or deep damage to the sidewall, the internal cord layers are compromised; no patch will prevent air leakage or potential accidents. I still remember last summer when a friend tried to save money by repairing a sidewall puncture—the tire blew out in less than half an hour on the highway, luckily without injuring anyone. Safety comes first; never skimp on the few hundred bucks for a new tire. Regularly checking tire pressure and appearance is key to prevention. After all, a car is just a means of transport—safe travels matter most, and minor tire issues can escalate into major problems.
