 New tires go on the back. Front wheel drive, rear wheel drive, all wheel drive. Tires go on the back. You have no control over the rear end of your car other than to have good traction. And the way you have good traction is new tires go on the back, not the front. And if you put them on the front and you get into a situation where you're going around a slight turn and it might be wet, slick.
