Buying 4 snow tires for the S ($125 each tire). Tire seller offers warranty for three years for $65. Since they are winter tires I will onyl get a chance to use them about 4 months each year so althoghter 12 months out of the possible 36 months warranty. The warranty is for nails, glass, crap like that.

So is it worth it? If I get one flat tire and get it replaced for free its already worth it. But its not like all season tired where I drive around all year with them. I will be only using them 1/3 of the year.

Also, what if say its like 2.5 years out of the 3 year warranty. Can I drove over some nails and get like two tires replaced for free?

Mods, I know this question talks about tires and I was gonna post it in the tire section but since the question is more general and involves maintenace and winter driving and other financial warranty crap I thought it would be more suited for general discussion.
