Abstract: A pneumatic tire having simplified structure and improved properties has mono-ply carcass having ply turn-ups closely wrapped around the bead hoop and extended to underlie breaker edges and the carcass cord angle in crown region is substantially radial at 85°-90° to the circumferential direction whereas in the sidewall region the cord angles of the main carcass ply portion and the turn-up portion are at a lower angle of 65°-85° and are crossed with respect to each other.

Abstract: A pneumatic tire having an inboard sidewall and an outboard sidewall when fitted to a vehicle including a reinforced carcass extending between bead regions through both inboard and outboard sidewalls and a tread region reinforced by a breaker extending between the tread edges beneath the rubber tread wherein the carcass in the outboard sidewall comprises a single ply of reinforced material having mutually parallel reinforcement cords extending substantially radially of the tire, the ply having one edge located under the breaker, extending from the breaker radially inwards through the outboard sidewall and being wrapped axially outwards around a bead hoop and being turned up to have its second edge radially outwards of the bead hoop, and the reinforced carcass for the inboard sidewall comprises a single ply of reinforcement material arranged with a first edge under and in overlapping engagement with the edge region of the outboard sidewall reinforcement, said first edge being adjacent to the inboard bead at an inboard shoulder, the single ply of the inboard side wall having a main portion extending radially inwards and a turn-up portion being wrapped around the inboard bead from inside to outside and extending radially outwards through the inboard sidewall to a point adjacent to an inboard breaker edge radially under said breaker and radially over the outboard sidewall ply in overlapping arrangement therewith.

Abstract: A vacuum intake horn is constantly secured to a portion of a land vehicle and connected to a vacuum generator to increase the load on the wheels and, thereby, enhance traction. In order to minimize the clearance between the intake horn face and road surface for greater vacuum force, the vacuum intake horn is attached to a portion of the vehicle such that movement of the vacuum intake horn relative to an associated wheel of the vehicle is no greater than 75% of the movement of the vehicle chassis relative to the wheel. The vacuum intake horn is mounted behind and substantially entirely within the outline of a tire, so that the tire protects the vacuum intake horn from debris and bumps in the road. In one embodiment, the vacuum intake horn is attached to the vehicle by a compensation arrangement that maintains the vacuum intake horn at a generally constant height close to the road surface despite tire deflection or movement of the chassis relative to the associated wheel.

Abstract translation: 真空吸气喇叭恒定地固定在陆地车辆的一部分上并连接到真空发生器以增加车轮上的负载，从而增强牵引力。 为了最小化进气喇叭表面和路面之间的间隙以获得更大的真空力，真空进气喇叭连接到车辆的一部分，使得真空进气喇叭相对于车辆的相关轮的运动不大 超过车辆底盘相对于车轮的运动的75％。 真空吸气喇叭安装在轮胎的轮廓之后并基本上完全在轮胎的轮廓内，使得轮胎保护真空吸入喇叭免受道路中的碎屑和碰撞。 在一个实施例中，真空进气喇叭通过补偿装置附接到车辆，该补偿装置将真空吸气喇叭保持在靠近路面的大致恒定的高度，尽管轮胎偏转或底盘相对于相关轮的移动。

Abstract: A pneumatic tire comprises a carcass extending around the tire from bead to bead, sidewalls and a rubber tread region which has a profile when considered in transverse cross section of a new tire terminating the sides of the tread in inner and outer shoulder regions respectively, each of said shoulder regions having a shoulder drop, which is defined by the distance in the radially inward direction from the point of maximum tire diameter to a shoulder point at the edge of the shoulder region, wherein when the tire is mounted on a scheduled wheelrim and inflated to a scheduled pressure, the tread region has its point of maximum tire diameter offset in the axial direction of the tire from the center line of the tire section in the direction of the inner shoulder, and the shoulder drop of the outer shoulder is greater than the shoulder drop of the inner shoulder such that the tread region has an asymmetrical profile.
