so the factory tires are starting to hum and drive me nuts at 45k miles, so i'm thinking of replacing them before one of my other two cars needs repairs and i can't afford it. this is the closest thing i've ever had to a truck or SUV, i've always had cars that i've put summer or high performance tires on, never a truck/suv tire. what are you guys running? it gets driven 80 miles a day and is NOT an off-road machine, so something tame but capable in the snow is what i want. what size won't mess with the speedometer? i have 215/60/17 on it now.
