Claims19
A studded tire system having a tire mounted on a wheel rim, comprising:
- (a) stud holes located in a tire shoulder tread block of a tire, having movable studs mounted therein;
- (b) conduits for air-free, incompressible hydraulic fluid in fluid communication with the movable studs;
- (c) a hydraulic pump for air-free incompressible hydraulic fluid having a piston and a pressure chamber, the piston and pressure chamber of the pump positioned centrally in the wheel rim to counteract imbalance and vibration when driving, said pump in fluid communication with the hydraulic fluid conduits;
- and
- (d) a wireless remote control for activating the hydraulic pump;
- wherein action of the hydraulic pump selectively causes the studs to protrude or retract in the stud holes.
