Abstract

A method for producing a vehicle tire, having the following steps: a) providing textile reinforcing supports; b) providing a bath which is free of resorcin and formaldehyde by at least: b1) adding at least one carboxylic acid to water; b2) adding at least one base; b3) adding at least one epoxy compound; b4) adding at least one polyisocyanate compound; b5) adding at least one VP latex; and b6) mixing the substances from b1) to b5); c) dipping the reinforcing supports from step a) into the bath from step b); d) subsequently hot-stretching the dipped reinforcing supports from step c); and e) further processing the reinforcing supports from step d) in order to form a reinforcing support layer in a vehicle tire blank. A vehicle tire which is produced using the method and to the use of reinforcing supports treated in such a manner in technical rubber articles are also disclosed.
