i didn't see this post before.
sorry to hear about your wife man....you have a guardian angel for sure now.
they may have changed the laws, don't know.....but when i lived upstate you could have them November to April.....where i lived we generally got snow from October to usually April, sometimes May.......one year i had snow under the pine trees on my land in June, think it was '98 or '99
After she and I moved to Kalkaska County (from Oakland County) back in the fall of 73' there were a few years where we used studded tires, but I forget what year it was the local tire place we went to, to get snow tires told us they couldn't sell them anymore because when people get stuck they would spin their studded tires and would slowly chew up the roads. So to save money (so they could spend it else where) the government made it illegal to sell them.
