I'm looking for the best "Training Wheel/Winter" tire for our STi. A fair amount of the training will be done on pavement and during the winter there aren't to many places to land off airport nearby so mostly pavement landings. Some of the locals run different tires in the winter instead of burning up the expensive Alaskas on the pavement which seems to make good sense. I am looking at either the Goodyear 26" which is truly only 23" and apparently fairly stiff or the 22" 8.50 Desser.
Does anyone have advice one way or the other? Or possibly another tire I haven't found, they will be going on Beringer sealed wheels so will be run tubeless.

Thanks in advance for your input.
