Youtube video just confirmed that there is more traction on the end of the car the pair of new tires are installed. The problem is what happens in a skid. Is the car “ündersteering” (front end skid) or “oversteering” (rear end skid) and the drivers reaction to those events. The normal reaction to any skid is braking the car. If the driver has less traction on the front of the car (old tires) the front end skids, driver brakes the skid is fixed. If the driver has less traction on the rear of the car (old tires) the rear end skids, driver brakes the skid is worsen!
