All rubber tracks didn't work out well on the Ram Ranger our snowmobile club has. The poor thing cann't paw it's way out of a road ditch with the groomer. The rubber lugs cann't get ahold of hard pack snow. Take the goomer off and it will go, but even then it will not go where the old SKi Dozer will. Steel grousers are IMHO a totally different track, and a better one IMHO. Steep grades and icy conditions would make me want to leave the Ram Ranger we have at home. Maybe why the low hours on this machine??
On marginal snow, and some bare ground, melting conditions ect. they probably would be fine there...
