Tire

A tire includes a tread rubber having a positive profile formed by at least one circumferential groove. Wherein the transverse grooves extends into the positive profile from the circumferential groove to form block flank surfaces. Further, the transverse grooves have bending points at which a change of direction takes place at an obtuse angle. Further still, at least one block flank has at least three flank surfaces, wherein at least one of the flank surfaces is inclined and connected to an upper surface of the positive profile. The tire is a vehicle pneumatic tire. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Tire with tread having transverse grooves forming block flank surfaces

Vehicle pneumatic tire with a rubber tread profile having blocks formed by circumferential grooves and transverse grooves. At least some of the transverse grooves are defined by first and second flank segments. The first and second flank segments have different angles with respect to a radial direction. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Vehicle pneumatic tire with transverse grooves defining flank segments having different angles

A tire including a tread rubber having at least one positive profile. Wherein the positive profile is formed by at least one circumferential groove. Further, the tire includes at least one truncated groove extending into the positive profile from the circumferential groove, such that the truncated groove includes at least one flank surface. Further still, the tire includes the truncated groove being inclined at an acute angle to a direction of rotation of the tire. The tire includes a pitch of the flank surface that continuously changes with respect to the radial direction over a length of the truncated groove. The tire being a vehicle pneumatic tire. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Vehicle pneumatic tire having truncated groove

A pneumatic tire for motor vehicles has a running surface profile designed in the direction of rotation, with two shoulder regions (S , S ) each being a constituent of a row of shoulder blocks, and with a middle region (C) separated from them by circumferential grooves ( ) running in the circumferential direction; this middle region encompasses the width of the circumferential grooves ( ) and covers a minimum width of 60% of the width of the running surface (B), is free from circumferential grooves running in the circumferential direction and is equipped with a number of V-shaped running rills ( ), which open into the circumferential grooves ( ) and whose V-peaks rest at least essentially on the equator line (M&mdash;M). In the two partial regions of the middle region (C) running to the side of the equator line (M&mdash;M) there are a number of slanting grooves ( ) which are oriented in the same direction to the course of the V-shaped rills ( ), crossing at least three V-shaped rills ( ) following each other in the circumferential direction and being at least essentially of a straight design, wherein these slanting grooves ( ) run at an incline at a much smaller angle (&bgr;, &bgr;&prime;) to the equator line (M&mdash;M) than the V-shaped rills ( ) and which are the widest of all grooves or rills of the profile, wherein the slanting grooves ( ) of the one partial region of the middle region (C) are offset in the circumferential direction with respect to those of the other partial region.
