| Description of the problem | We have a 2005 toyota sienna with all wheel drive (awd) and run-flat tires. The right rear tire disintegrated while on i80 at freeway speed. There was no warning by the tire pressure monitoring system, before or after the tire failure. I noticed a vibration earlier in the day and now suspect the tire had been flat for some miles. This was our second instance of a failure of a run-flat tire, but in the case of the left front tire, the warning light did come on. In both cases, it was necessary to replace all 4 tires due to the awd. In both cases an alignment has also been done, which includes resetting the speed sensors (tsb pg005-04), and no problems were detected. This indicates the system is inadequate to reliably detect a flat tire and a crash could have easily resulted. |
