摘要： A method of testing a tire is employed in an enclosed system having a drum enclosure connected to a tire enclosure by flexible bellows, the enclosed system configured such that a tire inside the tire enclosure abuts a drum inside the drum enclosure. The method includes rotating the drum at a first angular velocity, thereby causing the tire to rotate at the first angular velocity. The method further includes measuring a temperature at a first location adjacent the tire and blowing cool air into the tire enclosure when the measured temperature exceeds a predetermined temperature threshold. The method also includes measuring a humidity level at a second location and adding moisture in the tire enclosure when the measured humidity level falls below a predetermined humidity threshold.

摘要： This disclosure relates to an approach for monitoring a tire for a puncture based on a change in a voltage established based on a resistance of a material disposed within the tire. In one example, the material is a conductive material layer. In another example, the material is a resistive strip. The systems and methods described herein can monitor for a change in an established voltage over time that is a function of parameters including the resistance of the conductive material layer or the resistive strip, and an applied voltage, to provide an indication of the change in the resistance in the material. The change in resistance of the material can be indicative of the puncture within the tire. The systems and methods described herein can alert a vehicle operator of the puncture within the tire.

摘要： A toroidal tire structure has a circumferential tread portion, a pair of bead portions, opposite sidewall portions, and a target resonant frequency of vibration. A tuned mass-damper is operatively coupled to the tire structure. The tuned mass-damper has a counteracting resonant frequency of vibration that is predetermined with reference to the target resonant frequency of vibration.

摘要： Off road tires having a blended layer arranged in the crown portion are described for improving adhesion between the tread and underlying or adjacent tire components. Increased adhesion between tire components can reduce the frequency of separation and increase the service life of the tire. The blended layer contains a portion of the same material composition of a tire component that contacts the layer to ensure the blended layer has ingredients common with the adjacent component. As arranged between two tire components or layers, the blended layer can have a first portion and a second portion corresponding to compositions of the layers in contact with the blended layer. The incorporation of compositions in contact with the blended layer allows the blended layer to simulate entanglement between materials and increases the bonding strength between the layer and other components in the tire.
摘要翻译：描述了具有布置在胎冠部分中的共混层的越野轮胎，用于改善胎面与下面的或相邻的轮胎部件之间的粘合性。轮胎部件之间的附着力增加可以减少分离的频率并延长轮胎的使用寿命。共混层包含与接触层的轮胎组分的相同材料组成的一部分，以确保共混层具有与相邻组分共同的成分。当布置在两个轮胎组件或层之间时，共混层可具有对应于与共混层接触的层的组成的第一部分和第二部分。与混合层接触的组合物的掺入允许共混层模拟材料之间的缠结并增加层与轮胎中的其他组件之间的结合强度。
