# Service bulletin Tech Service Bul

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10127875
- Published by NHTSA: 2018\-02\-05
- Manufacturer's number: Tech Service Bul
- Manufacturer's date: 2012\-10\-10
- NHTSA component: TIRES; WHEELS

## NHTSA's summary

The tires subject to this recall were manufactured with irregular geometry in the casing turn up area, above the tire bead, in the lower sidewall. Under certain limited circumstances this irregular geometry can potentially spawn a lower sidewall crack and can lead to a loss of inflation pressure. In some cases, during use, this crack may become visible but in other cases, a separation may remain hidden within the tire. In most cases, this tire condition has no effect on driving safety at early stages. However, if left in service, the crack/separation could grow and the tire would become vulnerable to impacts and air loss could occur. Underinflated tires can change a vehicle?s handling characteristics. In extremely rare cases, rapid air loss may occur, increasing the risk of a vehicle crash.
