Problems solved by technology

These solutions, although satisfactory, have now reached their limits, because on the one hand, the material properties have improved, and on the other hand, for the same reasons, the static settings continue to increase

Embodiment Construction

[0028] The single figure attached to this specification shows a partial view of a radial tire 1 used in a combination according to the invention, mounted on a mounting rim 5 and inflated to its normal operating pressure. Seen in a meridian section, ie in a plane containing the axis of rotation (YY'), the tire 1 comprises a bead 4 in contact with a mounting rim 5 extending radially outwards through a sidewall 3 terminating in the There are 2 crown parts.

[0029] The mounting rim 5 comprises a seat 51 inclined with respect to the direction of the axis of rotation YY' in order to press the bead seat 41 against it. The rim well 51 extends axially and radially outwards by a rim flange 52 against which the beads of the tire can be pressed. The nominal diameter (Do) of said rim is measured at the point where the rim well and the rim flange intersect according to the provisions of the E.T.R.T.O (European Tire and Rim Technical Organization) standard. The height (J) of the rim flang...

Abstract

The invention relates to a road assembly comprising a vehicle that includes a front axle and a rear axle, and a set of tyres mounted on the mounting rims thereof to be fitted on the front and rear axles of the vehicle, the tyres of the rear axle including grooves having an average depth of 3 mm and not exceeding 5 mm, the tyres of the front axle including grooves having a depth higher than 5 mm, wherein said road assembly has, at least for the rear axle, static adjustments (camber, toe-in) close to zero, i.e. a camber for each wheel-tyre assembly on said axle of between -0.8 degrees and +0.8 degrees, and a toe-in at the wheel of between -0.15 degrees and +0.15 degrees, the static adjustments of the tyres of a same axle being equal in terms of absolute value and symmetrical relative to a plane perpendicular to the road surface.

Description

technical field [0001] The present invention relates to road running equipment consisting of a passenger vehicle comprising a front axle and a rear axle and a set or set of tires mounted on these axles, and more particularly to a vehicle for achieving enhanced rolling resistance properties without thereby reducing the wear of the tyres. specific assembly conditions required for performance. Background technique [0002] Passenger cars have evolved in this way over the past fifteen years to the same extent, now showing that the overall mass of the rolling assembly has risen and the vehicle's center of gravity has moved further off the ground and further towards the front of the vehicle. This means that there is a significant increase in the difference between the static and dynamic load on the axle, the load moving away from the rear axle with damage to the front axle. The rear axle is now relatively lightly loaded under static conditions and essentially unloaded under braki...
