TS ISO 4223-1

TS ISO 4223-1 is a terminology standard that defines significant terms used in the tyre industry for pneumatic tyres, together with the related codes, symbols and values. Pneumatic tyres are the tyre type that carries load through internal air pressure and plays a central role in vehicle performance, including grip, comfort and load capacity. This standard helps establish a common technical language so the terms are used consistently across industry documentation.

How the terminology is organised

The standard focuses on selected terms that are important in tyre engineering and commercial communication, and it links those terms with the relevant notations as well. That makes the terminology more than a simple word list: it connects definitions with the codes, symbols and values used in practice. In technical work, this kind of alignment is important for product data, catalogues, specifications and other documents where ambiguity can create confusion.

As the title indicates, this part is limited to pneumatic tyres. Terms relating to wheels and rims are handled separately, and the note points readers to the ISO 3877 series for other terms used in this field and their equivalents in other languages, as well as to ISO 3911 for wheel/rim terminology. In broader technical context, standards of this kind support consistency in design language, marking, measurement references and technical communication.

• Defines selected key terms for pneumatic tyres.
• Brings together the associated codes, symbols and values.
• Separates tyre terminology from wheel/rim terminology.
• Refers users to the ISO 3877 series for multilingual equivalents.
• Refers users to ISO 3911 for wheel and rim terms.
