Service bulletin WSB-06
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
On certain 2026 Open Trail Motorhomes, the rear inner tire has valve stem extenders installed that are not compatible with the tires on the motorhome. The current rear inner tire valve stem extenders do not allow air to pass into or out of the tire. Tiffin Motorhomes will remove the current rear inner tire valve stem extenders and install double seal flow through valves. Owners will need to utilize a long neck air chuck or flexible inflator to reach the inner tire. The repair will be at no charge to the customer.
