don't know if this will help , but when I go on iffy ice with my wheeler , a 200 trx honda , I inflate the tires to 30 to 35 lbs of air presure so that if the machine goes thru the ice it will float if you slide most of your weight off the seat. I haven't gone through the ice on my machine yet , but I know it will float from riding across deep water in the warm season.
