Commercial vehicles - Wheel-hub attachment dimensions
This document specifies the dimensions necessary for the attachment of a commercial road vehicle wheel on the hub of the vehicle whose fixing has six, eight or ten stud holes. This document considers the flat attachment type with centring on central bore, which is the recommended type for future equipment. Other types are currently in use. The specifications do not imply that the wheel is interchangeable from one vehicle to another.

Overview
ISO 4107:2023 is the international standard that specifies wheel-hub attachment dimensions for commercial road vehicles. It focuses on ensuring precise and standardized dimensions for wheels fixed on hubs with six, eight, or ten stud holes. This latest edition-published in December 2023-updates tolerances for modern manufacturing techniques and recommends the flat attachment type with centring on the central bore as the preferred mounting method for future equipment. The standard supports consistent design, safety, and compatibility within the commercial vehicle industry.
Key Topics
- Scope and purpose: Defines critical dimensions for attaching commercial vehicle wheels on hubs-crucial for six, eight, or ten stud configurations.
- Flat attachment type: The standard promotes the flat attachment method with a central bore for centring, enhancing wheel stability and alignment.
- Dimension specifications: Includes detailed bolt circle diameters, stud hole sizes, disc flat diameters, and central bore measurements, accommodating both ferrous and aluminium materials.
- Tolerances: Adjusted to state-of-the-art manufacturing capabilities, ensuring precision fit and improved safety margins.
- Non-interchangeability: Clarifies that wheel interchangeability between different vehicles is not implied by the specification, emphasizing the importance of correct wheel-hub matching.
- Applicability: Covers commercial vehicles with road-use profiles requiring robust, reliable wheel attachment standards.
Applications
ISO 4107:2023 applies widely in the commercial vehicle sector, particularly for manufacturers, maintenance personnel, and parts suppliers dealing with:
- Truck and bus wheel assemblies: Ensuring that wheels are accurately fitted for performance and safety.
- Vehicle design and manufacturing: Assisting engineers in designing hubs and wheels that meet international dimensional standards.
- Replacement parts industry: Guiding suppliers on wheel compatibility and attachment uniformity for aftermarket products.
- Safety and maintenance protocols: Enabling technicians to verify adherence to dimensional standards during inspections and repairs.
- Regulatory compliance: Supporting conformity assessments required by vehicle safety authorities across global markets.
Applying ISO 4107 dimensions reduces risks of wheel detachment, uneven load distribution, and failures caused by poor fitment, thereby enhancing road safety and vehicle reliability.
Related Standards
ISO 4107 interfaces with several related international standards relevant to commercial vehicle components and safety:
- ISO/TC 22 (Road vehicles committee): Covers broader technical standards for vehicle dynamics and chassis components.
- ISO 7250 - Basic vehicle dimensions: Provides general measurements aiding vehicle design including wheel positioning.
- ISO 7141 - Wheel studs and nuts: Addresses fastener specifications required in wheel attachment.
- ISO 11090 - Tyres and rims: Related standards for tyre-rim compatibility affecting wheel assembly safety.
Together with these standards, ISO 4107 contributes to a comprehensive framework of vehicle wheel and hub engineering, ensuring parts consistency and robust performance across the commercial vehicle industry.
By adopting ISO 4107:2023, commercial vehicle stakeholders improve wheel fitment accuracy, enhance vehicular safety, and comply with international quality requirements critical in a globalized automotive market.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
