I was driving my mom's car last night, and heard a LOUD poping sound from the rear tire, so I pulled over and checked the tires. Suprisingly, I found out that the driver side rear tire is TORN :yikes: (see attached picture). I quickly switched the damaged tire with the spare and I'm on my way.
But I was wondering, what could've possibly caused this? The street was clear at that time, and it couldn't possibly be caused by a single nail. Maybe its because of the age of the tires (they're on the car since new, haven't changed them for 7 full years since the car only has 57000kms to date), and they're getting more brittle over time? Or I'm just unlucky? SHould I change all 4 of them at the same time since I also noticed there are little cracks on the tread and grooves on the surface of the tire? Thanks for your advice! :dunno:
