How to Deal with Sidewall Scratches on Tires?

[LeRobert]

Tire sidewall scratches are relatively serious, it is recommended to replace them in time. Here is the relevant introduction about tire sidewall scratches: 1. Precautions: If the radial length of the sidewall scratch is less than 5cm and the axial length is less than 0.5cm, it can be repaired under such circumstances. In general, if more than three layers of the tire sidewall cord are broken, it is not recommended to repair it, and driving safety will be affected. If the broken cord layers are less than or equal to three, it can still be repaired under such circumstances. 2. Hot patching method: Hot patching involves attaching a special raw rubber patch to the wound and then using a baking machine to bake the wound until the raw rubber patch is completely bonded to the tire. However, hot patching can easily damage the cord layers inside the tire, leading to catastrophic consequences and increasing the hidden dangers of the tire. Therefore, hot patching is not very suitable for sidewall repairs.

A scratch on the tire sidewall is no small matter, and I need to handle it carefully to avoid accidents. The sidewall is the weakest part of the tire, and any damage can easily lead to a blowout, especially at high speeds, which poses a greater risk. After noticing a scratch, I first find a safe place to stop and check the depth: if it's a shallow scratch without exposed cords or bulging, it might still be usable temporarily, but I’ll reduce speed and avoid long-distance driving. If the scratch is deep or the cords are exposed, I’ll replace the tire immediately without hesitation—otherwise, the safety risk is too high. I always keep tire repair tools handy or call a professional for inspection. Additionally, prevention is key—avoiding curbs or sharp objects while driving can reduce the chance of scratches. In short, safety comes first. Don’t take risks trying to repair it to save money—when necessary, decisively replacing the tire ensures peace of mind on the road.

Last time I was driving on a suburban road, I encountered a cut on the tire sidewall caused by a stone, which really put me on edge. Experience tells me that upon discovering a cut, you must stop the car immediately and use a flashlight to check the depth and condition of the damage: if it's minor, like only the surface is damaged with no air leakage, I might still drive a short distance at low speed to a repair shop; if it's severe, like seeing the internal fiber layer, I would change to the spare tire on the spot or call for roadside assistance. It's also important to check the tire pressure to see if air leakage is worsening the problem. In daily life, I've learned to leave enough space when parking by the curb to avoid scraping against it, and regular checks of tire wear and pressure can help prevent issues early. Dealing with tire cuts is no small matter—acting promptly can avoid bigger troubles. Never delay like some people do, only to end up with a flat tire that costs more and poses greater risks. Safe driving is a responsibility, and I always take a quick look at my tire condition before every trip.

A sidewall scratch is not something to delay, I'll address it immediately to ensure safety. First, inspect the scratch: if the depth hasn't reached the cords, a minor scratch can be monitored for air leaks by applying soapy water for testing. However, if it's deep or the cords are exposed, don't hesitate—replace the tire immediately. Avoid high-speed driving at all costs; driving slowly to the repair shop is the safest option. Personally, I always keep a tire emergency kit in the car to save time in such situations. Additionally, regular tire maintenance is crucial, like checking tire pressure monthly to reduce the risk of sudden damage. In short, a quick response is better than neglect, and safe driving is the principle.
