I have a kit on order and am debating about the tires. Most of my flying will probably be on paved strips but my goal is to do a significant amount of flying from grass/dirt strips. As it stands I have ordered the 850 x 6 6 ply treaded tires with tubes. My decision is based on 1) I like the looks of the bigger tires 2) I think the larger tires will be better on grass/dirt and 3) I suspect the treaded tires will perform and wear better on paved strips. Since I have no experience with tail draggers and back country flying and only a few hundred hours flying light airplanes I am looking for advice/recommendations on my choice.
