Tire Sidewall problems of the 2002 Toyota Sienna

I purchased cooper life liner touring tires from kauffman tire. Within 2 weeks of purchase, one of the tires developed a large bubble on the sidewall. Kauffman staff told me this type of bubble was a result of "hitting a curb or other object. " I knew I had not hit anything. They replaced the tire with the same brand & model. As time went by, I had chronic problems with my vehicle pulling to the right. I visited kauffman several times. They adjusted my alignment and checked my tire pressure on several occasions, to no avail. Tuesday, July 3, 2007, I stopped by kauffman and told them there was apparently an underlying problem that caused my van to pull so severely that I had to struggle to keep in my lane. I requested that they do an in-depth check to determine the problem. They found that 3 of the 4 cooper life liner touring tires were defective, one had a bubble in the sidewall. Kauffman employee again told me that this type of problem was caused by striking a curb or other object. Again, I knew I had not hit the tire on anything. Kauffman employees replaced the tires with 3 new cooper life liner touring tires. On July 6, 2007, one of the new tires developed a huge bubble in the sidewall and left me stranded on the side of I-20 in alabama. An internet search led me to your website, where I found that the tires kauffman put on my vehicle in 2007 were recalled in 2006. I fear someone may be injured or killed by these failing cooper tires.

Tire vibration in steering at speeds usually greater than 40 mph and most prevelant when coming out of a turn. Tires evaluated by tire store, speed balanced and rotated. Found the sidewall defective. Michelin x-radial dt p205/70r15. When defective tire was moved to rear problem did not occur, moved back to the front problem came back.

Tires firestone: fr680, p205/70r15 95s, m+s. On a Toyota Sienna 2002. 2 tires were completely worn down to nothing. Got Toyota dealership to do a wheel alignment & replace 2 tires for free since I had been going to them for all service & they never noticed the worn tires. Now one rear tire has a sidewall tear. I took it to a firestone dealer, and he said it's not under warranty -- just wear and tear -- rim had a slight dent so he deducted it was because we hit a bump or sidewalk. But there is also a crack in the sidewall as well.

Tire burst at less than 30mph. 3+ inch rip through exterior sidewall along radial line of tire. No impacts or other adverse initiating events. No signs of other puncture. My wife was accelerating from a stop light. We are in the DC area and still have the tire (at the moment) for examination. This is a brand new tire with about 1000 miles on it. (tiresize: p215/65r15).
