It worked. To what degree I can't say yet, but 20 for 20 attempts up the snow covered hill the non-grooved tire broke free first. Unfortunately it was too dark to take video, but I will do some filming this afternoon.
As for the tire cutting I layed out the first few lugs, but just free handed it after that. All in all it took 45 min to an hour from start to finish. The groover handled it well, I only used 1 blade and it didn't seem to cut any different from the first to last cut.
