Title:

ALL YEAR TRACTION TIRE STUD SYSTEM

Document Type and Number:

WIPO Patent Application WO/2001/008907

Kind Code:

A1

Abstract:

All year traction tire stud system having leak proof transmission means like metal wires for moving studs in and out of stud holes on the tire shoulders. Said means also movable on the tire sides outside the tire casing. Optionally operated by wireless remote control from the driver's seat when driving on ice, snow, mud, wet grass, slippery terrain and roads.
