Lettering is circumferential, occupying two radial locations of the sidewall surfaces. Sidewall surfaces are conical in the lettered regions, with conical surface inclinations (alpha . beta ) measured with respect to the principal tire axis. Conicities are opposite and constant, intersecting at an axially-outer location. Lettering of the (adjacent) logos runs oppositely in the circumferential direction Preferred features: Logos are circumferentially offset by 180[deg]. Conical surfaces occupy the entire tire circumference. The first logo is on the visible, inner, conical radial section of the tire sidewall, the second on the outer, when in the operational state on the rim. The conical surfaces occupy one third of the radially inner and outer sidewalls. Between them, a scrub strip is formed. Characters of the logo are themselves part of the conical surfaces. They are raised, their surface curvature following conical surfaces.
