| PROBLEM TO BE SOLVED: To calculate and acquire height of only an irregularity defect by subtracting only a portion of an irregularity mark even when the irregularity defect exists so as to overlap on the irregularity mark.SOLUTION: In a tire shape inspection method for inspecting a shape defect of a sidewall surface of an inspection tire by using an image of a sample tire having a sidewall surface on which an irregularity mark is formed, the following processes are executed. First, as a teaching operation process, the boundary of the irregularity mark is detected, a mask image showing the boundary is generated, an area corresponding to the boundary shown in the mask image is removed from a sample original image of the sample tire, and a height offset image representing height of the remaining area by one or a plurality of offset values is generated in the sample original image. Next, as an inspection operation process, the height offset image is subtracted from an inspection image of the inspection tire, a boundary area represented by the mask image is simultaneously removed, and a shape defect of the sidewall surface of the inspection tire is inspected on the basis of an obtained irregularity removed image. | ||||||

In this tire, the sidewall portion ranging from a departing point (39) of the tire from a rim (34) to a tread end (40) is equally divided into three regions (A,B,C), and at least one annular recession (41,42,43) extending circumferentially of the tire is formed in an outer surface of each of these regions (A,B,C) in the sidewall portion so that a maximum depth (d) of each annular recession (41,42,43) is at least 0.3 times an original rubber gauge (D) at a position corresponding to a deepest point (47) of the annular recession. |

| PROBLEM TO BE SOLVED: To improve stability and riding comfortableness during cornering without losing stability at the time of straight advancing by forming a ridge line for forming an outward projecting part in a connecting point of a tire fattress part and a side wall part. SOLUTION: A fattress part 5 directly below the end of a tread part 4 has a recessed outer surface, and a ridge line 6 for forming an outward projecting part is provided in a connecting point of the recessed outer surface and outer surface 3 of a side wall part. Thus, by clearly separating the curved surface of the fattress part 5 from the curved surface of the side wall part 3, rigidity is reduced during cornering without reducing the rigidity of a tire at the time of straight advancing. Also, the curvature radius RB of a fattress recessed region is set in the range of 20 to 45% of the curvature radius Rsh of a tread shoulder part. If this value is lower than 20%, the rigidity of the tire is excessively reduced causing the deterioration of straight advance traveling performance and thus so-called drifting occurs. On the other hand, if the value exceeds 45%, rigidity at the time of straight advancing is excessively increased. | ||||||

| PURPOSE: To prevent the coulisse to a tire and improve the durability of a bead part by forming at least one step for lessening the thickness of a sidewall, between the contact part with A rim flange of the outside surface of the tire and the largest width position of the tire. CONSTITUTION: Two steps 6 and 7, which form step shapes within the step range of 0.2-5mm, are made, respectively, in the direction of reducing the thickness of a sidewall 5, toward the side of the largest width position of a tire from the side of a rim flange, within required area between the contact part with the rim flange 3 of the outside surface of the tire and the tire largest width position 4. And, for these steps 6 and 7, main curves 8 and 9, the centers of the curvatures of which lie inside the tire, and following curves 10 and 11, the centers of the curvatures of which lie outside the tire, are continued. Hereby, the durability can be improved by effectively reducing the deflection of the bead part and the heat occurrence, and besides at molding by vulcanization, the occurrence of the coulisse to each step 6 and 7 can be prevented effectively.

| PURPOSE: To reduce the rolling resistance of a pneumatic tire 11 by decreasing the distortion energy loss, using a simple configuration, which is generated at the side wall of the tire 11 with load rolling. CONSTITUTION: A plurality of ring-shaped recesses 41, 42, 43 apart from one another in the radial direction are formed at the outside surface of a side wall 14, and thereby the deformation generated in the side wall part 14 at the time of load rolling is concentrated around the deepest part 47 of the recesses 41, 42, 43. Thereby the rubber deformation (distortion energy) in the other parts than the deepest part 47 is reduced, and the rolling resistance of the pneumatic tire concerned 11 is lessened.

CONSTITUTION:In the ground contact surface of a tire at the time when the tire has been assembled in the normal rim and the normal internal pressure has been filled and the normal load has been loaded, the ratio of the ground contact surface Al of the land 1 to the total ground contact area A including the land 1 and the sea 2, or (Al/A), is made to be the land ratio Ra, and denoting by R1 the radius of curvature at the central part of the tread, R2 the radius of curvature at the shoulder part, and R3 the radius of curvature at the shoulder edge, the land ratio Ra is made to be 0.5<=Ra<=0.58, and the radius of curvature R2 at the shoulder pat and that R3 at the shoulder edge part are set so as to satisfy the relationship 14.0<=R2/R3<=20.0. Further, the radius of curvature R1 at the central part of the tread and that R2 at the shoulder part are set so as to satisfy the relationship 2.90<=R1/R2<=3.10. | ||||||

| PURPOSE:To prevent the damage in beads, in a high-speed heavy-load tire for an aircraft, by specifying the ratio of the radius of curvature of the circle passing through the maximum width point of the tire, the point of a prescribed times of total sectional height from the bottom of the bead, and the point in the middle height between both the above points to the maximum width. CONSTITUTION:The ratio R0/W is set to be less than 0.54, where R0 is the radius of curvature of the circle passing through the maximum width point C where the width W of a tire 1 becomes maximum, the point Q apart from the bottom surface 3A of the bead by the distance equivalent to 0.2 times the total sectional height H of the tire 1, and the point M is the middle height between both points C and Q, and W is the maximum width of the tire 1. Thus, the profile of the tire becomes of a shape swelled in the lower part, and the damage to the bead parts can be prevented without requiring change in the structure of tire and also without reducing the traveling performance. | ||||||

| PURPOSE:To enhance the durability of a heavy duty pneumatic tire by forming a plurality of concave curved section in the lower area of the outer surface of each side of the tire, and by forming both end parts of each concave curved section in a convex shape. CONSTITUTION:The outer surface T of each side of a tire in a lower part B below the part having the maximum tire width W is formed with a plurality of concave curves. These concave curves may be also formed in the upper area A of the outer surface of the side of the tire. Further, the cross points (m) between these concave curves are made to be convex outward of the tire cross-section. With this arrangement, the outer surface of a discontinuous part in the tire internal structure may have a large thickness while the outer surface therearound may have a small thickness so that shearing strain due to tire deformation in the discontinuous part in the tire internal structure is made to be less, thereby it is possible to enhance the durability of the tire. | ||||||

| PURPOSE: To improve various performance of a tire and prevent heat generation by forming an outer wall having a circular concave part in the direction of tire circumference from two circular arcs having different centers between a shoulder and side parts. CONSTITUTION: A tire forms an arc of a radius R 2 of curvature through a virtual point 1 of a shoulder part so as to form a concave part at the position 2 of a height l = (2/3-3/4) × height SH of cross section of the tire from a bead hill 7 on an arc of a radius R 1 of curvature from a side part B. The formation can form the circular concave part 2 at the prescribed position of an outer circumference of the tire to obtain an effect for enlarging an apparent flexible zone, improve various performance such as traction, braking and cornering, and control heat generation.
