What size tire injuries can these patches repair?

These 4.75-inch patches are designed for crown, shoulder, and sidewall injuries on bias-ply tires. The large diameter provides comprehensive coverage for various punctures and damage types. Always consult tire repair guidelines and ensure the injury size falls within acceptable repair limits for safety.
