Abstract: The invention is directed to a pneumatic tire that can be mounted on a rim (wheel) to assure good engagement with the rim while preventing the occurrence of rim offsets. The bead portion 4a (as indicated by a solid line in FIG. 1) on the front side of a tire 1 which is later mounted on the rim has a bead base diameter .phi..sub.1, a toe portion angle .phi..sub.1, a contact angle .alpha..sub.1 , and a heel portion radius R.sub.1, whereas the bead portion 4b (as indicated by a dashed line in FIG. 1) on the back side of the tire which is first mounted on the rim has a bead base diameter .phi..sub.2, a toe portion angle .theta..sub.2, a contact angle .alpha..sub.2 and a heel portion radius R.sub.2. The bead portion 4a on the front side has a different shape than the bead portion 4b on the back side and the following two relationships hold between the two bead portions; the angle of .theta..sub.2 of the toe portion on the back side should be greater than the angle .theta..sub.1 of the toe portion on the front side, with the difference between the two angles being not more than 4.degree. (4.degree..gtoreq..theta..sub.2 -.theta..sub.1 >0.degree.); and the bead base diameter .phi..sub.2 on the back side should be greater than the bead base diameter .phi..sub.1 on the front side (.phi..sub.2 >.phi..sub.1); preferably, the difference between the bead base diameters on the two sides (.phi..sub.2 -.phi..sub.1) is 2 mm or less (.phi..sub.2 -.phi..sub.1 .ltoreq.2 mm).

Abstract: This disclosure relates to a tire, a rim and a combination thereof that yields improved stability characteristics when the tire is run flat. The combination of this invention yields a structure wherein the tire will operate normally under normal conditions of load and pressure and will operate with the load equally distributed on each sidewall of the tire during run flat operation. In this invention, the tire has an asymmetric sidewall construction resulting from the inclusion of rubber inserts in its sidewalls of different bulk and the rim has axially outward extending rim flange extensions which are angled in relation to the axis of rotation of the rim. The extensions are angled in opposite directions. The proper combination of these features compensates for the camber that the tire is subjected to when it is run flat.

Abstract: A tire rim for a rolling apparatus with wheels mounted with a camber. The rim comprises a first shoulder having a first diameter, a second shoulder having a second diameter, and a main body arranged for connecting spoke elements, wherein the first diameter is larger than the second diameter. By having the first diameter of the first shoulder larger than the second diameter of the second shoulder the restrains of the tire at the first shoulder will be different than the restrains of the tire at the second shoulder. By mounting a wheel, comprising the tire rim according to the invention, with a camber, wherein the first and second shoulder have a substantially similar distance to the floor, the tire may be supported substantially more opposite to the floor.
