Tire With Sidewall Bubbles
At a glance, it looked like this tire had a serious case of the chicken pox or the mumps. But the mechanic knew what had caused this. A side wall bubble is caused by air leaking from the tire’s interior into the tire’s body. This is often the result of impact damage. And judging from the look of this tire, it had suffered some major impact either by another car or someone who took a bat and beat the heck out of it.
