ABSTRACT:
An improved all-weather vehicle tire having traction enhancing studs located in a position outside the normal tread area which allows a vehicle operator to selectively choose operation as a conventional tire on dry roads or as a studded tire on ice-coated roads by the simple expedient of reducing or increasing the air pressure within the tire. Specifically designed for areas which experience ice storms or freezing rain which remains on roadways for relatively short periods of time, the tire provides excellent traction on ice, yet may be quickly and conveniently returned to conventional tire operation with little effort by the vehicle operator.
