So my car came with a set of winter tires. Two are in very good shape, while two seem to be worn more. I'd say they have another winter or two of driving left in them. I'm curious about where the more worn ones should go. Right now they're in the front to help with traction as this is a front wheel drive car. But a guy at school said his tire guy says to put the worn ones up front and the better one in the back to avoid the rear of the car losing grip?

What do you guys do? Right now the front makes sense to me, but it isn't a big deal to switch either, changing tires on this car is pretty darn easy. I think the jack almost tipped it over.
