I am thinking about getting Eagle GT's (http://www.tirerack.com/tires/tires....nSpeedRating=T) , they got good reviews. Anyone ever run these? Or make a suggestion for another tire. Only requirement it has to be all season, since I go to college in a very snowy climate.

Also on a side note, I am thinking about upgrading to 18" wheels. Will I have to get my speed odometer adjusted?

 

I have sold a few sets with good responses from my customers.
But have not heard anything on how the do in the snow.
My best professional guess is they will do average.
If you go to an 18" wheel, you just want to get a tire thats close to the OE diameter
235/50/18 or 255/45/18
If you do move into the 18"s keep the 17"s and get some cheap snow tires for the winter.
