Final answer:
Tire damage within 2 inches of the tread shoulder or on the sidewall should not be repaired due to concerns for safety and the integrity of the tire.
Step-by-step explanation:
You should not repair tire damage that occurs within 2 inches of the tread shoulder or on the sidewall. Tires are constructed with structural integrity in mind, and damage that occurs too close to the sidewall can compromise the tire's strength and safety. Repairs to this area cannot ensure reliable durability, and as such, it is often recommended to replace the tire entirely to maintain the safety of the vehicle. While certain types of damage in the central tread area can be repaired under proper conditions, damage to the sidewall is particularly concerning because it bears the weight of the vehicle and is subject to flexing and high stress as the tire rolls.
