摘要： This invention relates generally to tires having treads that have a configuration and/or properties for providing suitable snow and dry traction, and, more specifically, to a tire that has a tread that has a maximum value for sipe density in the contact patch, a minimum value for lateral groove density in the contact patch, and a minimum value for the longitudinal contact surface ratio. In certain embodiments, the pitch length of pitches or repeating units of tread geometry along the circumferential direction of the tire is within a certain range and the tread depth is below a specified value. Tires with treads having a configuration that falls within these design parameters exhibit a desirably good level of snow and dry traction.

摘要： The invention concerns a suspension device linking a wheel carrier to a vehicle body, said wheel carrier being designed to bear a wheel of radius r', said wheel being designed to rest on the ground (S) via a contact zone, said device comprising means for providing the wheel carrier, relative to the body, one degree of freedom of camber and one degree of freedom of suspension clearance mutually independent. The invention is characterised in that said device is configured so that the cambering movement of the wheel carrier relative to the body allows, about a mean position, an instantaneous centre of rotation (CIR r/c) located in an interval ranging between 2.5 r above the ground to r below the ground.
