Jim, I read your comments on the gear with great interest. I know on your plane you have the split gear and regular tires. Based on your experience would the motorcyle type tires be tough enough to handle the abuse? I had thought about going with straight axle/spoked wheels, but the more I think about it, the better the split/ballon type tire seems to make more sense. Especially since I'll be feeding my plane a steady diet of hard surface runways.Thanks!Gary M.________________________________________________________________________________

Mike,I agree with you on the 4-wheel drivers, my brother was almost killed by a woman who was meesing with her kids and not looking for riders on motorcycles. I gave up streetbikes a long time ago! I have seen a lot of cycle action, though. I used to race motocross when I was younger, and yes, those tires do take a lot of abuse, But I'd hate too see one of my old knobbies if I hit the concrete with 1200 lbs of airplane on one wheel in a crosswind! I also don't have tire screws or tire clamps in this plane, I had those on my race bikes, so who knows what that bead would do given enough pressure I wonder how well A Harley's tires would hold up if you dropped it straight down 5 or 6 feet onto concrete? Certificated aircraft and their tires have to sustain a 10 foot fall, I've got to wonder if they're up to that or not The loads you mentioned were load imposed in a building manner, not a sudden shock like a botched landing would be. I doubt if there is very much impact pressure on a 150 MPH street tire. As far as side loads, if you look at the way a motorcycle turns, there is little side load even on a road-race bike. To turn one of those, you have to lean the bike over, so the bulk of the weight is still pushed straight up though the tire. Another thing, how much tread is on the ground on cycle tires vs aircraft type tired? Grass and nostalgia are nice, but the reality is, my plane will spend most all of it's life on hard-surface runways, and I like directional control after landing, to me more rubber can only help. I also think that given a soft surface the spoke wheels/cycle tires might be better than "regular" tires on a soft runway, although, they'd tend to sink in worse. Anyway, cycle tires will probably do the job, maybe they won't. I know Air-Hawks or Flight Customs will, and I feel like some of the 4-wheeler style tires will, too, I'm not really worried about the spoked wheels themselves being able to take the load, just that skinny little strip of rubber. But even given all those arguments, I'm still considering the spoke wheels/cycle tires - they just look soooo cool!Two more cents.Gary M.________________________________________________________________________________
