Summary

Tiffin Motorhomes was notified by Daimler Trucks North America on behalf of Freightliner Custom Chassis Corporation of a defect that exists on specific model year 2017 - 2022 Freightliner Custom Chassis X-Line chassis manufactured February 20, 2017 through November 18, 2021 that are equipped with a valve stem extension and stabilizer configured with a specific tire valve stem and wheel combination. Tiffin Motorhomes built motorhomes on these specific Freightliner chassis between April, 2017 through December 6, 2021. Certain chassis may have been built with the tire valve stem extension for the inner wheel contacting the outer wheel rim opening, potentially damaging the valve stem resulting in a loss of air pressure in the inner tire. A loss of air pressure in the inner tire on a motorhome with a single drive axle may overload the outer tire and increase the risk of a crash.

Owners of these vehicles have filed 10 complaints in the tires category.
