i have 8 wheels(thanks to dudesky) so in the summer i run 17's and in the winter i run snows in the back and those traction t/a's in the front(got em w/the car), they are 205/65/15 i think, but i couldnt tell you how good they are because i dont drive my car that hard in the winter, but havent had a ny problems with them yet(and they are on the front, not the back anyway)
