Not only are the angles (&#x3b2;, &#x3b3;) that the steel cords in the second and third belt plies () form with the circumferential direction (A-A) approximately equal, but also the angles (&#x3b1;, &#x3b4;) that the steel cords in the first and fourth belt plies () form with the circumferential direction (A-A) are likewise approximately equal.

Pneumatic vehicle tire with four steel cord belt plies

A pneumatic vehicle tire for commercial vehicles is provided wherein the wet traction properties are improved with simultaneously good rolling resistance properties. At least 120 transverse grooves are arranged in each of the central profile ribs over the entire circumference of the tire. The width (B) of the transverse grooves in the central profile ribs is maximally 1.5 mm at a distance of 3.5 mm from the profile surface, and the width of each inner circumferential groove is maximally 4 mm at a distance of 3.5 mm from the profile surface.
