2006 Chevrolet TrailBlazer LS 4dr SUV 4WD (4.2L 6cyl 4A)
After five days and only 250 miles of driving my 2006 Trailblazer the left rear tire blew out while driving on the Interstate at 70 MPH. I was able to safely get the vehicle onto the shoulder. When I examined the tire, I noticed the sidewall had seperated from the tire tread. I'm an automobile mechanic and have seen this type of damage many times. It is caused from driving on a flat tire. I had not idea that I had a flat tire, the ride, stability and handling of the vehicle did not give any indication of a flat. To cause the sidewall to seperate, I had probably driven several miles with the tire flat. It handled so well in this situation that I feel very safe driving it.
Looks, handling, stability and 17 mpg city 24 mpg highway, 372+ miles per tank of gas.
Relocate the ONSTAR buttons so that accidental activation (adjusting rearview mirror) does not occur.
