I use re-molds, they were called re-treads mounted on their own rims. Super cheap, 215 85 16 about US$ 45.00 each. I have them studded. In Maine you must get a lot of snow like ours in Nova Scotia, WET, turns to ice at the frist spin of a wheel, the studs give that little extra bit of traction.
If you're close to the New Brunswick border you might want to check on our side for prices your dollar is worth 1.50 CDN. These tires are very soft and wear VERY quickly on pavement, but give better traction in snow then any NEW tire I have ever tried from Goodyear to BFG to Michelin. If you don't put too many highway miles on them and take them off in the spring they'll last 2 seasons plowing.
A GOOD snowtire won't last long in warm weather on pavement, and a mud tire doesn't mean it will be good in snow. A narrower tire will go through more snow than a wide one, so instead of 245 75 16, go with 215 85 18 same diameter.
Save your hard earned dollars for a quality set on road tires like Michelins for summer use, and highway miles
