The tire () for a passenger vehicle has an axially central portion and axially lateral portions. The axially central portion and each axially lateral portion satisfies just one of conditions I, II, III: I—the portion comprises no transverse cut ('), II—the portion comprises N transverse cuts (′) arranged in such a way that π×OD/N≥40 mm, III—the portion comprises N transverse cuts (′) arranged in such a way that π×OD/N≤24 mm, condition I or II being satisfied by the axially central portion or by an axially lateral portion, and condition III being satisfied by the axially central portion or by an axially lateral portion.

Low-noise tire

A tire () having at least one sidewall (), intended to interact with a sidewall insert () by way of an anchor (), and aims to personalize the design of the sidewall. The anchor (), has a recess () formed in an axially outer sidewall layer (), with a protuberance (), which is raised in relation to the recess bottom () and extends from the recess bottom () to the vicinity of the axially outer sidewall face (), and the protuberance () is constituted by a stepped arrangement of a first narrow portion () having a minimum width Lpmin and a second wide portion () having a maximum width Lpmax, such that the difference Lpmax−Lpmin is at least equal to 1 mm and at most equal to 4 mm.

Tire comprising a sidewall insert

A tire () having at least one sidewall (), intended to interact with a sidewall insert () by way of an anchor (), and aims to personalize the design of the tire sidewall. The anchor has a recess () formed in an axially outer sidewall layer (), with a protuberance (), which is raised in relation to the recess bottom () and extends from the recess bottom () to the vicinity of the axially outer sidewall face () and the protuberance () has, in any meridian plane (YZ), a minimum width Lpmin in the vicinity of the recess bottom () so as to ensure the anchoring of the sidewall insert () intended to interact with the anchor ().

A motor vehicle sheet-steel wheel rim (), including axially, from the inner side to the outer side, an inner hook (), an inner seat (), a connecting zone (), a mounting groove (), a hump (), an outer seat () and an outer hook (), the rim being intended to be joined to a wheel disc () under the mounting groove (), wherein with the rim having a given thickness E in mm at the mounting groove (), the connecting zone () includes a zone (Z, Z') of thickness Ein mm such that:E/3+0.5 mm&#x2267;E24 E/3 mm; andE&#x2267;0.7 mm.
