How to fix a small crack on the side of a car tire?
2 Answers
Solutions for a small crack on the side of a tire are as follows: 1. If the sidewall of the tire is scratched, it is essential to replace the tire as soon as possible to avoid the risk of a high-speed blowout. 2. If the damage to the contact surface exceeds 4mm, the tire must also be replaced promptly, as both internal and external repairs pose potential dangers. 3. It is not advisable to use the vehicle before inspecting and repairing the tire (especially if the front tire is damaged). It is recommended to remove the tire to check for internal punctures. Considering safety, if the puncture is in this location, repair is not recommended, and replacement is necessary. 4. If a small crack on the side of the tire damages the cord fabric, the tire should be replaced immediately.
I've been driving for over a decade, and my biggest concern is always tire issues. When you see small cracks on the sidewall, never take them lightly—the sidewall is the weakest part of a tire, and under pressure, those cracks can expand suddenly, leading to a blowout. I remember my relative once had an accident due to a high-speed blowout from a similar situation; thankfully, they were wearing a seatbelt and were unharmed. My advice is to pull over immediately and inspect: if the crack is deeper than the thickness of your fingernail or exposes internal cords, you must replace the tire right away. If unsure, visit a professional repair shop for an instrument check. For routine maintenance, I make it a habit to check tire pressure and appearance weekly, avoid taking turns or speed bumps too fast to minimize impact. Safety always comes first—don’t risk it to save money. Generally, tires should be replaced regularly after six years due to aging.
