Is it a Sur Trac Lenny?
jr37 - personally I'm not a big fan of them if you only have one groomer. But they have their place on straighter trails or RR grades. My friend runs a grooming operation and two of their three groomers are Sur Tracs. They don't seem to have very many problems at all. Just my .02 and we all have our opinions on groomers right??!! LOL!!!
EDIT - Lenny - I talked to my friend with the two Sur Tracs and they do not run foam in their tires. In the several years they have had them they have had a tire go down 1X. He commented that there must be something in the tracks causing the tires to constantly go down. He went on to say that the foam will likely add a lot of weight but that might not be an issue for you guys.
