The invention relates to a utility vehicle tire tyre having a tread with at least one circumferential channel (″) with a channel base () and channel walls (′). Base elevations are formed on the channel base. A top surface (″) of the base elevations (″) slopes downward uniformly toward the surface edge, wherein the channel walls (′) have, to the side of the base elevations (″), wall sections () which are convexly curved toward one another.

Utility vehicle tyres

The invention relates to a pneumatic vehicle tire having a tread with profile block rows () with profile blocks () delimited by channels (), which channels () form T-shaped intersections in plan view and are delimited by a channel base (') and by block flanks (), wherein, in channels (), there are formed projections (&#x2032;) which, in a radial direction, have at their highest point a height (h, h&#x2032;), in relation to the lowest point of the channels (), of 10% to 80% of the profile depth. The projections (&#x2032;) are positioned in intersection regions of T-shaped intersections of the channels () and are attached to that block flank () which is situated opposite the opening-in point of the opening-in channel ().

Pneumatic vehicle tyre

A pneumatic vehicle tire, in particular a commercial vehicle tire, includes a tread which has a profile and has at least one circumferential groove () which is encircling in the circumferential direction, is embodied to a profile depth (P) and in the cross section, starting at the tread external face, is composed of three adjoining groove portions, one outer groove portion () that expands in a funnel-shaped manner toward the outside, one 1 mm to 3 mm wide contracted groove portion, and one inner groove portion () which lies radially inward, is expanded in relation to the contracted groove portion () and has the largest cross-sectional face of all portions, and which is delimited by two cover flanks (a), lateral groove flanks ('b,&#x2033;b) that adjoin said cover flanks (a), and a groove base (c).

Pneumatic vehicle tires

Tread profile of a pneumatic vehicle tyre&#x2014;in particular for commercial vehicles&#x2014;comprising a regroovable tread profile with radially raised profile elements () and with grooves (), which respectively separate two adjacent profile elements () from one another, wherein the grooves () are bounded inwards in the radial direction R by a groove base () and on both sides in the axial direction by a profile element flank, forming the groove wall (), and wherein at least one regrooving indicator () for indicating the regrooving depth is respectively formed in one or more grooves (), characterized in that, in at least one groove (), all of the regrooving indicators () formed therein are formed in a groove wall () at a height H measured in the radial direction R of H&#x3e;0 mm above the groove base (), wherein the height H corresponds to the maximum radial abrasion position of the tyre for regrooving.
