Abstract

A cap ply for the belt reinforcing member of a pneumatic vehicle tire. The heat shrinking reinforcing elements of the cap ply are oriented in the circumferential direction of the tire, and consists of monofilament threads or monofilament cords, and have a filament fineness of at least 250 decitex. These monofilaments fulfill a wrapping function, and at the same time are airtight. The monofilaments also prevent corrosion of the steel plies of the belt.
