Abstract

PURPOSE:To reduce the thickness of a tread in a tread grounding end to improve the operation stability on a dry road without generating the dislocation of a carcass line by setting a tread width at a predetermined value or less. CONSTITUTION:In a spare tire provided with, at least, two pieces of carcass ply 1 and having a tire width narrower in comparison with target standard tire, the filling internal pressure is set higher at 1.5 times or more. A width TW of a tread surface part 2 is set at S.7X0.40(mm) or more and S.7X0.65(mm) or less. Here, S.7=S1X(180 deg.-sin<-1>W1/S1)/135.6 deg., S1: tire design cross sectional width (mm). W1: rim width (4T=102) (mm). Thickness of a tread part is set so as to satisfy the expression HP-C<1(mm). Also, HP: tread thickness (mm) in the normal line direction at the grounding end, C: tread thickness (mm) at the tread center. A negative ratio is set within 40-60%. Weight reduction of a tire and the improvement of the performance thereof are thereby compatible at a high level.

On the other hand, for the purpose of reducing the weight of the tire, the thickness of the tread portion, mainly the tread contact edge, is maintained without changing the tread width, that is, without changing the tread tread shape. When the thickness in the line direction is reduced, as shown in FIG.
By changing from P 2 to HP 3 , the inner liner and squeegee of the tire hump part were sucked up to the tread end side, and the carcass ply was drawn from the original design shown by the solid line in the figure to the broken line in the figure. As shown, the distance C
Therefore, there is a problem in that it is impossible to secure an appropriate inner liner thickness and squeegee thickness.
