TS ISO 4223-1

TS ISO 4223-1 is a terminology standard that defines a number of significant terms used for pneumatic tyres in the tyre industry, together with the associated codes, symbols and values. Standards of this kind support consistent technical language, helping manufacturers, specifiers and users describe tyre-related concepts in the same way across drawings, catalogues, product data and engineering communication.

What this part covers

The focus of this part is a selected set of important terms connected with pneumatic tyres. In general technical usage, a pneumatic tyre is a tyre designed to perform its load-bearing and service functions with the support of internal air pressure. Because tyre terminology is used in sizing, marking and product identification, agreed definitions matter: they reduce ambiguity when describing dimensions, characteristics and related values. This part provides that common vocabulary for the terms it includes, but it should be read as a defined selection rather than a complete tyre dictionary.

How it relates to other terminology standards

The note in the scope points readers to ISO 3877-1 to ISO 3877-4 for other terms used in this field and their equivalents in other languages, and to ISO 3911 for terms and definitions relating to wheels/rims. That distinction is important because tyres, wheels and rims are related but distinct technical components, and confusion between them can lead to errors in sizing, compatibility or documentation. In broader technical context, this standard helps align terminology used throughout the tyre industry.
