One of the tires has a sidewall bubble. I looked around on the internet and this seems to be a common problem with kumho tires. I went to the dealer we purchased the tires from and they said that I was the 4th person there that day with kuhmo tires that had sidewall bubbles. Also, the tires are wearing out much faster then they should be. Luckily I check our family tires once a month. If someone does not check them these sidewall bubbles could lead to a blowout and serious accidents. I believe there should be an investigation and recall of these kuhmo ecsta asx tires.

While driving under icy road conditions the front passenger tire blew out. The consumer replaced the tire and 5 months later the replacement tire blewout. On the first incident, consumer noticed a bubble on the right rear tire sidewall. On the second incident, a bubble was also seen but this time it was located on the right front tire sidewall. On both incidents, both tires were replaced.

Michelin tire on Acura TL type S developed a bubble after about 10,000 miles. Originally accepted dealer's explanation that it came from hitting a pothole, but on line I discovered that many people had developed bubbles. I've attached a few comments from tirerack.com. Are these tires safe?

So I went and checked mine sure enough I have two tires with bubbles. I called two of my friends that have the same car both also have bubbles. Went to the Acura dealer to complain and saw two more customers cars with bubbles. Called Michelin they gave me the pothole excuse sorry Michelin didnT hit any potholes your product just sucks.

Tires- Michelin Pilot hx mxm4 215/50 17. Had 2 tires that had to be replaced in the last 1000 miles because of sidewall bubbles. Told that it was caused by potholes and was not covered by warranity. I do not feel that I ran over any major potholes, and I feel small road cracks etc should not cause this.
