    A wheel rim having a well for tire fitting and adjacent each bead seat a circumferentially extending groove formed to accommodate an extended bead retaining toe of a tire wherein at least one air pressure release passage is provided from a point within the groove positioned such that a correctly fitted retaining toe covers the point. The passage may comprise a groove across the bead seat or a hole through the rim.

    The invention relates to vehicles, namely to wheels of vehicles on pneumatic tires.
    The wheel rim of a pneumatic, tireless tire is known, containing side flanges and landing flanges for tire beads, a rim stream and at least one annular canal for inserting a protruding toe of the tire bead and located between the rim brook and the landing flange tl.
    The tire for which such a rim is designed has an axially protruding axially and radially inside sock on the respective board or sides, which interacts with the groove or grooves, which provides the node with a highly efficient tire bead restraint system even in the event of a complete lowering of the tire. It was found that when installing a standard tire on a rim of this type it is impossible to obtain a satisfactory connection that would be completely safe. Under exceptional driving conditions, air loss may occur, in particular in cases where

    lateral effort, even with psellia inflated tire. One of the means to ensure the reliability of the node when using modern standard tires. With a standard bead and rim of the type described above, having one or two grooves located near the landing flanges, is the use of a gasket for the grooves. However
    to it is possible that the groove tool will be mounted incorrectly or not at all, which will result in the wrong assembly. Such a node and essentially any other
    1B, an incorrectly assembled unit does not ensure reliable retention of the bead of the tire, as in the above example, especially if there is a toe protruding on the bead.
    The purpose of the invention is to improve driving safety by increasing the reliability of the fit of the tire on the rim and prevent the use of an incorrectly mounted tire.

    This is achieved by the fact that the rim is made with at least one air exhaust duct connecting the said annular groove with the atmosphere and the toe overlapping
    thirty . properly mounted tires.
    The beginning of the air outlet channel is preferably located on the annular groove surface mating with the landing flange and may be located in the center of the cross section of said groove surface. In addition, the duct may be made in the form of an axial groove extending along the surface of the flange and on the rim flange or in the form of an axial groove, passing along the surface of the rim flange to the through-hole in it.
    Figure 1 shows the cross-section of the proposed rim with tire assembly; figure 2 - the same, with a standard tire and gasket grooves.
    The rim of the wheel has side edges 1, landing shelves 2 stream 3 rims and annular grooves 4, which are used to insert the toe 5 of the bead
    6 tires. On the axial outer surface of the groove 4 there are channels
    7dl air release, overlapped toe 5 bead tires with its proper installation.,.
    The assembly shown in Fig. 1 has a tire with an axially and radially protruding toe 5, made on each side of the tire, and conventional reinforcing cores "
    The material of the nose is chosen so that the tire bead is rotated under the influence of a lateral load applied to the tread, but is retained on the landing flanges, even if the tire is completely deflated. Sock 5 enters the groove 4, and the hole 7 is located on the outer surface of the groove so that the sock closes it and prevents air from being released from the tire.
    If the tire is mounted on the rim incorrectly, for example, if the toe 5 is not fully installed in the clutch 4, the air will come out of the tire and it can be inflated. Thus, the holes 7 provide an opportunity to check the correctness of mounting the tire on the wheel rim.
    If a tire is mounted on a similar rim with a standard design, standard 6-inch 6, there are no shortcuts: the nose 5 protruding in the radial and axial directions will require filling the groove 4 and closing the opening 7, otherwise the air will come out of the tire through opening 7, This prevents the assembly from being incorrectly assembled.
    FIG. 2 each; navka filled with filler 8, forming the surface of the tire bead. Filler
    The 8 grooves are made of rubber and close the holes 7 so that the wheel can be inflated. In this case also incorrect mounting of the tire on the rim, the displacement of the accumulator 8 from the groove 4, or its part, or the absence of a filler and the groove will not ensure the preservation of air in the tire.
    The air ducts can be of any convenient size, and there may be more than one gram of such a channel in the groove. Their location around the circle does not play a special role.
    If there are two or more channels, they can be interconnected, for example, with a small groove running along the surface of the groove.
    If the air ducts are in the form of .KaHaBotc, each of them must be deep enough to ensure effective leakage when mounting the tire on the rim. The diameter of the hole can be in the range of 0.75 to 3 mm. For passenger cars, the preferred range of hole diameters is 1.0-1.5 mm.
    The use of the proposed rim, eliminating the possibility of installing incorrectly mounted tires, contributes to improved driving safety,
