Does a cut on the tire require replacement?

[MacJuliette]

It is recommended to replace the tire. You can feel the depth of the "wound" with your hand. Generally speaking, the rubber layer of a tire has a certain thickness, but for the sidewall of the tire, this is a weak spot. The rubber thickness here is not enough to provide sufficient and effective protection for the tire. If you can see a cut on the sidewall of the tire with the naked eye, one thing is certain—the scratch is no longer shallow and may even compromise the structure of the tire. Additional tips: 1. Pay attention to tire pressure: Both excessively high and low tire pressure can cause abnormal wear and shorten the tire's lifespan. During the harsh winter and summer seasons, you can adjust the tire pressure regularly based on recommendations from maintenance service stations. 2. Avoid sudden acceleration when driving: A sudden start from a stationary state causes intense friction between the tire and the road surface, accelerating tread wear. 3. Reduce emergency braking: Emergency braking worsens localized tread wear and can easily lead to tire bulges or delamination. It is advisable to use coasting to slow down more often and minimize the use of braking, especially emergency braking.

The other day when I was driving, my tire accidentally scraped against the curb and got a cut. At first, I thought it wasn't deep and ignored it, but then it blew out as soon as I hit the highway—scared me half to death. The cut might look small, but if it's on the sidewall, the tire's inner layers could be damaged, making it prone to bulging or bursting under pressure. In such cases, it's absolutely not repairable—you must replace the tire immediately. If the cut is shallow and short on the tread, it might be repairable after inspection by a professional. As a car owner, safety comes first—don't try to save money like I did. Also, be careful when parking; don't get too close to the curb, as aging tires are more susceptible to damage from scraping.

Having driven for a lifetime, I've seen plenty of tire cuts. If the cut is deep or long, especially on the tire sidewall, replacement is a must—otherwise, it could blow out at any moment and cause a disaster. Small, shallow cuts on the tread might be temporarily patched in an emergency, but you should confirm safety at a repair shop. The internal structure of a tire is complex; once the cord layers are damaged, patching is useless and affects handling and braking. The key is to pull over immediately and inspect—don't push your luck. Regular maintenance should include checking tire pressure to avoid prolonged underinflation, which increases the risk of cuts. In short, life is more valuable than money—replacing tires early saves worry.

As a mom, I'm particularly concerned about tire safety. If we find a cut in the tire, my husband immediately replaces it with a new one. Damage to the tire sidewall is the most dangerous as it can easily lead to a blowout, threatening the whole family's travel safety. For small cuts on the tread, we might use a temporary solution after having a mechanic check it. But for larger cuts, there's no room for negotiation – replacement is mandatory. For peace of mind, I usually avoid driving on gravel roads and choose flat parking spots. Regular tire inspections are essential to ensure worry-free driving.
