I am a new Mooney owner (1979 M20J) and want to replace the main gear tires and tubes. A friend (who doesn't fly Mooney's) suggested the Desser Retread Monsters. Does anyone have any experience with these tires? Will they fit in the M20J wheel wells? If not the Desser's, other recommendations? Any recommendations for tubes? And, what valve type (straight, 90 degrees, etc.) works best? Thanks for the information and help.
