摘要： A process for producing a tire having an expandable chamber utilized for extending and retracting studs provided in the periphery of the tire. In one embodiment, a non-stick film is strategically positioned between the casing and the tread prior to curing the tread onto the casing. The interface at either side of the film forms the sides of an expandable chamber. The tread side of the chamber is inset and studs are affixed thereto. Expansion of the chamber extends the studs out of the inset and into engagement with a road surface. Alternative processes provide a channel in the tread and the expansion chamber formed in the channel.

摘要： The sector mold (11) is designed so that, during the molding phase, the molding elements (10, 10a, 10b, 10c) are all equidistant due to devices (13) which assure an elastic repulsion between each other. Some of the elements glide circumferentially with respect to their sector (11) in the final closing phase. In this way, pinching of the rubber between sectors and the appearance of molding burrs are avoided.

摘要： A vehicle tire comprising a tire carcass (3) and on top of this a cap (29) consisting of at least one rubber quality and forming the tread (7), the cap having anti-skid stud holes (5) extending from the tread to its inside. At the bottom (8) of the anti-skid stud holes (5) and thus under the bottom flange (21) of the anti-skid studs (20) elastic cushions (6) are provided, made of a material of an elasticity higher than that of the rubber quality forming the said cap (29).

摘要： A pneumatic tire, particularly for tractors or other like vehicles, having a tread portion containing alternating, spaced-apart medium and long lugs proceeding axially inward from a lateral tread edge, and an identical (but opposite in hand) set of long and medium lugs proceeding axially inward from the other lateral tread edge and offset circumferentially so that a long lug emanating from one lateral edge is opposite a medium lug emanating from the other lateral edge. The lugs have bar portions which are smoothly curved axially inward from the tread edge in the direction of intended tire rotation and bulbous head portions transitioned into the bar portions axially inward thereof, to provide excellent traction and wear characteristics while minimizing vibration.
