I don't think you can blame uneven tire wear on torque factor in an airplane the size of a KR, or even a four place Cessna or Piper, for that matter. I've never seen uneven tire wear on an aircraft that size caused by anything other then wheel alignment (camber / castor), (wrong) inflation pressure, or piloting skills (flat spots from landing with the brakes on), or a combination of the three. If you are getting a 2:1 tire wear on one side you have something wrong with your gear alignment. What type of tire wear are you getting? Excessive wear on one edge, inside or outside? Excessive wear in the center or both edges? One or multiple flat spots on the tire? I have my main gear (tail dragger) set as close to zero /zero as I can get them and the couple of sets of tires I've gone through in 350 hours wear out very slowly and evenly and my 0-200 has more torque than a VW.
