Title:
DIFFERENT DIAMETER BEAD TIRE AND MOUNTING METHOD THEREOF
Document Type and Number:
Japanese Patent JP3313775
Kind Code:
B2
Abstract:
PURPOSE: To improve straight advancing performance and wearing resistance in a different diameter bead tire by improving its lateral force deviation.
CONSTITUTION: A different diameter bead tires 10A, 10B are mounted by facing a major diameter bead 12 toward the outside of a vehicle. A direction of a reinforcing cord of a belt ply, positioned in the outermost in a diametric direction of the different bead tires 10A, 10B, is tilted at an angle less than 90° to a side of the major diameter bead 12 from here with a tire rotary direction, in a vehicle mounting condition further at vehicle advancing time, serving as the reference. When the different diameter bead tires 10A, 10B are rotated on a road surface by advancing a vehicle 30 to run, unity C and plysteer P are negated each other, to decrease lateral force deviation, and as a result, straight advancing stability and wearing resistance of the tire are improved.
