A rim (3) for a tire has an axis of rotation DD and a rim seat (31) extended axially towards the outside by a rim flange (32), said rim flange (32) having a first portion (321) that is oriented substantially in a perpendicular plane and is situated radially on the outside with respect to said rim seat (31), characterized in that said rim flange (32) has a second portion (322) that is inclined towards the outside, is situated axially on the outside with respect to said first portion (321) and is situated at least partially radially on the outside with respect to said rim seat (31), said rim having a connecting portion (320) between said first portion (321) and said second portion (322).

An annular and ring extends around the interior of a wheel/rim on which a tire is mounted. The inner diameter of the annular ring is sized for a snug fit on the wheel rim. A tensioning cable extends through the tubular ring and opposed arms are attached to the ring and are movable between disengaged and engaged positions. The apparatus is selectively movable by actuation of a cable tensioner between a first, disengaged position where the arms do not engage the tire and thereby lock it to the rim, and a second, engaged position in which the arm bear against the tire beads, capturing the tire beads between the rim flanges and the wing members to lock the tire to the rim and to create and/or enhances the air-tight seal between the tire and the rim. The bead lock apparatus may be beneficially used in combination with a foam insert for enhanced tire performance.

A dual, internal, pneumatic, boltless beadlock assembly for effectively securing a tire to a rim is disclosed. The beadlock assembly exerts a force on the two circumferential inner beads of a tire such that the tire stays in secure contact with the rim, even when the inflation pressure of the tire is not sufficient to lock the tire to the rim.

The present invention discloses a pneumatic tire.

The pneumatic tire includes a bead portion and a rim flange provided outside the bead portion. The rim flange is made of a rubber resistant to ozone and fatigue and a hardness reinforcing rubber portion is interposed between the rim flange and the bead portion. The pneumatic tire of the present invention avoids a change in the physical properties of the flange rubber, ozone cracks caused by ozone present in the air, and fatigue cracks caused by frequent flexion and extension to achieve improved handling stability and straight ahead ability.

A pneumatic tyre includes a pair of bead portions having respective bead cores therein, each bead core defining a core innermost end in a tyre radial direction, and an inner liner having an air-impermeable property and extending between the pair of bead portions, wherein in each of the pair of bead portions, the inner liner comprises an innermost end in the tyre radial direction located inwardly of the core innermost ends in the tyre radial direction, and the pair of bead portions has a bead base diameter being less than 99.7% of a rim diameter of a standard wheel rim on which the pneumatic tyre is to be mounted.

A commercial vehicle tire intended for mounting on an E.T.R.T.O. Standards Manual standardized 15 drop-center rim (width codes 5.25 to 9.75) with two rim flanges (2) and with two rim sections (3), each with a bead seat surface (3a), wherein the commercial vehicle tire has two bead regions with bead cores (4) and in each case one bead toe (6) and one bead contour on the outside of the tire and one on the inside of the tire, which bead contours adjoin one another at the bead toe (6), wherein each bead contour on the outside of the tire has a first segment (S.sub.1), which is in contact with the rim flange (2) when the commercial vehicle tire is mounted on the rim (1), and an outer contour region, which is at least partially in contact with the bead seat surface (3a) when the commercial vehicle tire is mounted on the rim (1).

The outer contour region is made up of three adjoining segments (S.sub.2, S.sub.3, S.sub.4), specifically a second segment (S.sub.2) which adjoins the first segment (S.sub.1), which comes into contact with the rim flange (2), at an external angle (.sub.1) of 190 to 225, a third segment (S.sub.3) which adjoins this second segment at an external angle (.sub.2) of 165 to 175, and a fourth segment (S.sub.4) which adjoins this third segment at an external angle (.sub.3) of 200 to 210, wherein the total width (B) of the second, third and fourth segments (S.sub.2, S.sub.3, S.sub.4), projected onto a reference line (g.sub.2) running at an angle () of 15 in relation to the second segment (S.sub.2), is 20.0 mm to 45.0 mm and wherein the fourth segment (S.sub.4) has a width (b.sub.4) of 20% to 35% of the total width (B) in this projection.
