FIELD: automotive industry; tire industry. ^ SUBSTANCE: proposed mounting rim contains two seat places on rim of different diameter tilted outwards and extended outwards in axial direction by two projections of small height. Smaller diameter seat place is connected axially from inside support surface by means of conical section, and larger diameter seat is connected axially from inside with said support surface by small height projection whose inner wall in axial direction has generatrix arranged at angle relative to axis of rotation opened outwards in axial direction and in radial direction and not exceeding 30°. Said projection contains inner conical wall in axial direction with axial width whose value does not exceed axial width of second seat place on rim and is provided with two cross grooves of small size circumference. ^ EFFECT: improved reliability of pneumatic tire. ^ 6 cl, 4 dwg |
