Never tried that myself as it is illegal to run like that. Found out the hard way by getting the ticket when I snagged an old cavalier and drove it home from the junkyard with only donut spares on it. Got 2 miles (out of the 40+) away from home and Mr Police Officer kindly pulls me over, tickets me, AND calls a tow truck to take the vehicle away, which added another 130 bucks to the cost of the car.
