Did you get the shaved 29x11x10s ? When I bought my Alaskan Bushwheels 10" wheels with the 29" Airhawks, I debated on regular stock Airhawks with the deep grooves or the shaved ones. I decided on the unshaved, but have always wondered if I made the right choice. I haven't installed them yet so I don't know any of the relative merits, either way. I like the shaved tires idea of a little less weight and the absence of the tread grooves' possible danger of picking up gravel or rocks, flinging them at the prop or tail. The N.E. Oregon Alaskan Bushwheels guy also sold me the double puck Cleveland wheel and brake kit, 199-62 for the conversion. I'm looking forward to the improved braking action. Now I have to find a better tailwheel set-up!
