Must a small cut on the tire sidewall be replaced?
2 Answers
It needs to be replaced. From the perspective of tire structure, the tire sidewall is the weakest part of the entire tire. The tire sidewall is composed of cords and rubber. When there is a cut on the tire sidewall, under the same conditions, this area bears relatively greater pressure, increasing the risk of a tire blowout. Below is relevant information about tire damage: 1. Conditions of tire damage: Tire damage includes tread cracks, tread bulges, missing tread rubber, severe sidewall wear, and multiple punctures by foreign objects. During daily vehicle use, tires can be punctured by foreign objects or accidentally hit against things, all of which can cause tire damage. 2. Consequences of tire damage: Damaged tires can lead to unstable tire pressure, increasing the likelihood of a blowout while driving, which may cause the vehicle to lose control. During high-speed driving, the integrity of the tires is crucial. Unstable tire pressure can cause vehicle shaking and also increase fuel consumption.
I once had a small crack on the sidewall of my tire while driving. At first, I thought it was no big deal, but it almost caused a blowout on the highway. The sidewall is the thinnest part of the tire, containing steel belts and ply layers. If it gets damaged, it can lead to air leaks or deformation, and a blowout could be disastrous. Later, I asked the mechanics at the repair shop, and they said the tire had to be replaced—it couldn’t be patched because patches can’t withstand the pressure on the sidewall. Always check your tire pressure before driving, and don’t cut corners to save money. Safety comes first—reliable tires give you peace of mind on the road. I recommend getting a full tire inspection regularly, especially before long trips. Small precautions can prevent big disasters.
