Problems solved by technology

From a steering point of view, a composition with sufficient stiffness is required, but on the other hand a composition with too much stiffness results in the transmission of minor road irregularities to the vehicle and thus reduces occupant comfort
On the other hand, again, tires that are favorable from an occupant comfort standpoint can be detrimental to directional handling and cause "sluggishness", which is perceived as sideways wobbling or lack of directional stability in driving

Embodiment Construction

[0042] using the arrows, figure 1 The regions that may be considered to be included in the bead area 5 , the sidewall 4 and the tread 2 are generally indicated. The arrowed areas are not exact and in various tire compositions these locations can be slightly different. With regard to the carcass 3 , the figures refer only to individual components, but the carcass covers almost the entire cross-sectional area of ​​the tyre.

[0043] According to a preferred embodiment, the aramid fibers have a length of 3±1 mm, preferably 3±0.5 mm. In addition, according to a preferred embodiment, the aramid fiber has a diameter of 5-30 μm. Individual strands of aramid fibers within the range defined by these dimensions have given particularly good results in tire research work.

[0044] exist figure 1 In the embodiment shown, said outermost sidewall layer 41 of the vehicle tire is the layer immediately outwards from the body cords 30 . In this solution, possible slash or puncture forces fo...

Abstract

A vehicle tire (1), comprising - a tread (2) intended for rolling contact against a surface, said tread (2) having been formed with a tread pattern (20) comprising circumferential grooves (25) and transverse grooves (26) for removing water from a contact patch between the surface and the tire (1), - a tire carcass (3) comprising at least one body cord (30) and a belt structure (32), - a bead area (5) comprising a bead wire (50), a clinch (52), and an apex (54), - a sidewall (4) comprising an outermost sidewall layer (41), a sideways rising portion of the clinch (52), a body cord (30), and an innerliner (31), - the outermost sidewall layer (41) is constructed from a rubber compound which contains 0,2-0,5% by weight of aramid fiber having a fiber length of 1-5 mm.

Description

technical field [0001] The invention relates to a vehicle tire comprising: [0002] - a tread intended for rolling contact against the ground, said tread having been formed with a tread pattern comprising circumferential grooves and transverse grooves intended to provide protection from the contact patch between the ground and the tire ( contact patch) to remove water, [0003] - a tire carcass comprising at least one body cord and a belt structure, [0004] - the bead area, which includes the bead wire, the clinch and the apex, [0005] - A sidewall comprising the outermost sidewall layer, the laterally rising portion of the clinch, the body cords and the innerliner. Background technique [0006] During vehicle operation, tires are subjected to a variety of stresses which should not cause tire damage. One such type of stress is a stab or chop force applied to the side of the tire, which may be caused, for example, by a vehicle colliding with a curb or by a loose object ...
