2020 Coachmen Encore problems

Filed Oct 7, 2021 · Tires · MO

Motor coach trip from St Louis to Austin TX 17SEP 2021. Once parked, owner noted that inside left rear tire on driver side had no tread on it. Tires were as received when motor coach was purchased in January 2021. Owner was able to locate a tire for replacement and mobile service to mount and install. Technician immediately noted that the treadless tire did not match the tire size of the other five tires on the coach. The tire he removed is a 235/80-R 22.5 XRV; the other tires on the coach are 255/80-R 22.5 XRV. Technician indicated that because the tire did not match the other tire next to it the tire spun, not rolled, and the tread was worn off, like a pencil eraser when it is used. Technician theorized that if the outer tire had a blowout the coach possibly could have flipped, at a highway rate of speed while also towing a vehicle. Motor coach manufacturer indicated that they receive the chassis, and that I need to contact the chassis manufacturer about the incorrect tire size. Currently attempting to retrieve that information from FORD.
