How to Deal with Linear Cracks on Tire Sidewalls?
2 Answers
Check the extent of damage on the tire sidewall. Inspect whether the crack has expanded and if it has caused damage to the cord. Visit a repair shop to have professional technicians repair or replace the tire.
Never ignore a linear crack on the tire sidewall! Last week, my neighbor's car had a sudden blowout on the highway because of this, almost causing a rear-end collision. What looks like a thin crack is actually a sign of internal cord layer fracture, which can tear completely at any moment. Tire repair shops will outright refuse to patch it—the sidewall is too thin and bears bending pressure, making patches or mushroom plugs ineffective. The safest move is to head straight to a tire shop for a new replacement. When changing the tire, ask the mechanic to carefully inspect the other side for similar aging cracks. Also, avoid scraping curbs when parking, as sidewall scratches are the most likely to become hidden hazards.
