How to Repair Scratches on Tire Surface?
2 Answers
Tire surface scratches cannot be repaired; the tire needs to be replaced immediately. Below are relevant extended details: 1. Tire cord layer: When the tire's cord layer is scratched, even if the scratch depth is less than 4 millimeters, the tire must be replaced. If not replaced, the tire will lack the support of the cord layer, failing to maintain tension, which can lead to a tire blowout. If the cord layer is not damaged, the tire can still be used even if the scratch depth exceeds 4 millimeters, as the cord layer ensures the tire's tension. 2. Daily tire maintenance: Check the tire pressure before driving, replace tires on time when they reach a certain age, and regularly inspect the tires for any foreign objects.
As a daily driver, I recently dealt with a tire scratch issue. If the tire surface has shallow scratches, there's no need to panic. I usually start by thoroughly cleaning the scratched area with soapy water to remove dirt, then let it dry completely. Next, I apply some specialized tire repair glue or rubber sealant, gently spreading it over the scratch to fill the crack. This simple method works quite well, especially for shallow tread scratches. After treatment, I always check if the tire pressure remains stable and avoid high-speed driving for a few days to monitor for air leaks or other abnormalities. Safety comes first—if the scratch is too deep or exposes inner layers, it's better not to risk DIY repairs. Instead, take it to a professional auto repair shop for inspection, as a tire replacement might be necessary. Don't hesitate to spend money when safety is at stake; life is more precious. Being mindful of sharp objects while driving can help prevent such issues.
