Matthew Johnson asked 4 months ago
Hi, I recently experienced a dramatic tire blowout while driving on the highway. The tire wasn't visibly worn out, and I had checked the pressure not too long ago. Additionally, I wasn't carrying a heavy load, and I'm pretty sure I didn't hit any potholes. I'm perplexed about what could have caused this sudden tire failure. Could it be a hidden defect or something else I overlooked? What's wrong with my car?

Hi there, Matthew! Sorry to hear about your highway tire blowout – that must have been quite alarming, and ultimately, I'm glad that you're safe and sound! There are a few potential causes for a tire blowout under the conditions you described:
  1. Previous Underinflation: If the tire was underinflated in the past, even if not recently, it could have suffered internal damage. Driving on a low tire can overheat and weaken the sidewall, leading to a blowout later.
  2. Age of the Tire: Tires can degrade over time, even if they look fine. Rubber deteriorates and loses its elasticity, which can lead to a blowout. Check the DOT code on the tire for its age.
  3. Slow Leak: A small puncture could cause a slow leak, leading to gradual underinflation. Sometimes, these leaks are so slow they’re hard to detect until it’s too late.
  4. Hidden Damage: Previous incidents like hitting a curb or pothole can cause internal tire damage that's not visible from the outside.
  5. Defective Tire: Though less common, manufacturing defects can cause blowouts. This would typically be covered under a warranty if the tire is relatively new.
  6. External Factors: Road debris or sharp objects could have caused a sudden puncture.
For future safety, it's good practice to regularly check your tire pressure, inspect tires for signs of wear or damage, and replace tires that are over six years old. If you're unsure, it’s always wise to have a professional inspect your tires periodically. Stay safe, and I hope that answers your concerns! Zack - Motor Verso Mechanics Team
