Ok, so I'm a high school student and, as such, on a rather limited budget. <p>I'm currently driving on Dunlop studless snow tires. They have plenty of tread left on them. I'm considering keeping them on until they're worn out and then just buying all-weather tires. I've heard some people say that this is fine as long as I don't mind a bumpy ride and sub-optimal gas mileage, but others who claim that running snow tires at too high a tempurature causes the rubber to "melt off," or at least wear a lot faster. <p>Any advice? Keep in mind, I'm trying to spend as little money in the short term as possible.
