A wheel (10) having a rim (14) and a tire (12) mounted thereon. The tire (12) has a rim contacting portion (28) and a bead or roll resisting hoop (32). A circumferentially extending substantially inextensible strengthening member (38) is mounted in said tire (12) adjacent said rim contacting portion (28) for increasing the interference fit between the rim contacting portion (28) and the rim (14) and for stiffening the rim contacting portion (28). Many existing tires suffer movement of their rim contacting portion (28) with respect to the rim (14). In many cases this abrasion is not pronounced and/or localized. This serves to erode the rim contacting portion (28), increase tire rolling resistance, and permit the build-up of heat. By stiffening the rubber adjacent the rim (14) and by improving the interference fit between the tire (12) and rim (14) as achieved by the present invention, this relative motion is decreased or eliminated. |
