Three problems related to tire have been reported for the 2007 Chevrolet Trailblazer. The most recently reported issues are listed below.
Vehicle has 31k miles. A flat tire occurred and the vehicle was taken for repair. The repair facility indicated that they could not repair the tire since the tread had reached through wear bars. This vehicle has been properly maintained with correct tire pressure and tire rotations. No accident or injuries were sustained as a result of the incident but the tire wear was not an issue at the last service, and if it were not for the flat tire, would not have been noticed until the next service which would have occurred after the start of the snow & ice season. Tire was on the right rear. Left rear tire also showing considerable wear, just short of the wear bars.
Tread split open on inside. No indication of being caused by an outside force. Contitental contitrac tr p24565r17 load index & speed symbol -105s dot tire ident - a38t bl6 tread - 520 tract - a temp - b tire ply comp - 4plies, 2 polymers, 2 steel sidewll, 2ply polyester.
Bought brand new chevy Trailblazer from gm and noticed middle tread wear on all 4 tires around 13k, took vehicle in at 25k since tread was below 2/32 while outer tread fine at 5/32 on all 4 tires. Even had tires rotated by dealer when wear noticed around 13k. Gm would not cover tires and was not notified to contact tire manuf. Contacted tire manuf (continental) and they stated they would not cover anything since I had different tires put on by the dealership now. Have documentation from onstar showing proper inflation every month that vehicle has been owned. No one will cover cost or take responsibility for bad tires.
