Nexen tires N5000 plus sidewall on all tires are starting to crack and split with less than 30,000 miles and 24 months of use. Going to replace tires with another brand and remove these due to unsafe and potential catastrophic failure of tires coming apart or blowout at highway speeds..

My 06 BMW 550I is having an electric wheel lock fault just like thousands of others this as you know could possibly lead to an accident. It is my understanding that BMW has issued a service bulletin acknowledging the issue. Any assistance is greatly appreciated.

I own a 2006 BMW 530I with 37,000 miles on original set of Bridgestone rft tires 275/40 R1893Y. These are low profile tires and on Nov 16, 07 < brought my car in for a tire check at the dealer. They determined that the rt rear wheel was cracked and has damaged the tire. This they said was not covered under warranty as they say that it was damaged from a pot hole. I said that I have been driving cars like Cadillac, Mercedes, corvette and never broke a wheel. They would not cover it and it cost me $900. Now on April 11, 2008, I went to my tire dealer that I have been buying tires from for 20+ years. He said the left rear and front wheels were cracked and also ruined the left rear tire. I am very unhappy and would like to know if the BMW 18" wheels on the above mentioned tires are defective.
