Tire Sidewall problems of the 1999 Chrysler 300M

I bought a set of yokohama tires for my 1999 Chrysler 300m in July 2006. We have several problems with these tires not holding air. Finally, now, the right front tire blew 2 half dollar size holes in the sidewall of the tire for no apparent reason. We were able to keep the vehicle on the road as to not cause further damage. We have taken the vehicle to tires plus for the previous problems as well as this blowout. We will obviously be replacing all four tires and will not be buying this brand again.

On 04/26/06, while at a sams club store, I noticed a large bulge in the sidewall of one of the two goodyear eagle LS 225/55r17bw tires that I purchased from walmart and had installed by walmart on 03/28/06. The tire was determined by a tire associate at the sams club store to be unsafe to drive on, so he removed the wheel and replaced it with the spare. I am taking the tire back to walmart on 04/27/06 to get a credit to be applied toward the purchase of a replacement tire.

The consumer stated that all 4 tires cracked along the sidewall. The total usage of the vehicle was less than 33,000. The consumer stated that while driving the tires lost pressure which resulted in a blowout.
