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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11026506-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11026506-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11026506","components":[{"id":"wheels","name":"Wheels","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"TIFFIN","model":"OPEN TRAIL","year_from":2026,"year_to":2026,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
