Service bulletin RC000221SAOwner

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.

NHTSA's summary

According to the tire manufacturer, Continental Tire the Americas (CTA), the affected tires may have an overcure condition and CTA has initiated a safety recall for these tires. According to CTA, overcured tires may experience a carcass break in the sidewall with sudden air loss or could develop a belt edge separation which could lead to partial or full tread/belt loss. These conditions may increase the risk of a crash. This affects the following Thor Motor Coach products: model year 2019 Quantum & Freedom Elite, 2019/2021 Daybreak & Four Winds, and 2019-2021 Chateau motorhomes.
