New tires should go on the rear axle, not the front. Worn rear tires lose grip on wet roads and cause the car to spin out. New tires in back keep the vehicle stable and under control.
When you replace only 2 tires and put the new ones on the front, leaving bald tires on the rear, you are putting yourself in serious danger. On wet roads, those bald rear tires lose all grip, the back end kicks out, and your car spins completely out of control. Now watch what happens when you put the new tires on the rear, where they belong. The rear holds firm. The car stays in control. Always put your new tires on the rear. No exceptions.
