Re: GV with 9R tires.

COMPLETELY different chassis, wheels and OE tires.
Michelin 255/80R22.5 fits on the OE 6.75" wheels. I do not know if this is the wheels on the Oshkosh chassis, but was used on several other Foretravel models with 9R22.5 tires. If 7.5" rims, then the 265's in many brands are a good option.
Don't know about the 265/75R22.5 in other brands. The 6.75" rim is not recommended.
