Re: Smaller Diameter Wheels - What's the advantage?

For anyone who is interested in data regarding contact area and traction, my daughter April posted a paper (do a CD-media search in papers on "traction") several years ago where she took measurements using Brecoflex belts and carpet. Basically, the higher the pressure (lower contact area for a given weight) the higher the traction, because the wheel digs deeper into the carpet and gets a contribution from the normal force that contributes to the sliding resistance.
