R117
Rolling Resistance & Noise Test Basis
Interacts with EU labelling framework - test methodology basis for label performance parameters
UN ECE type approval is the gateway to market access in the 60-plus countries that are contracting parties to the 1958 Agreement on Wheeled Vehicles, Equipment and Parts, administered by the United Nations Economic Commission for Europe. Three regulations are directly applicable to tire manufacturers: Regulation R30 governing pneumatic tires for motor vehicles and their trailers (covering PCR, LCV and general purpose tires), Regulation R54 governing pneumatic tires for commercial vehicles and their trailers (covering TBR and heavy-duty tires), and Regulation R75 governing pneumatic tires for motorcycles and mopeds.
A fourth regulation, R117 covering rolling resistance, wet grip and rolling noise test methods, interacts with both the EU Tire Labelling Regulation and the type approval framework - providing the test methodology basis for the performance parameters disclosed on the EU label. UN ECE type approval under R30, R54 and R75 is not a one-time certification activity. It is an ongoing compliance management program: each tire size and type designation requires a separate type approval submission, and changes to approved types require assessment against change notification requirements of the applicable regulation.
The ongoing compliance management requirements under UN ECE type approval are substantially more demanding than the initial certification activity - because product portfolios change, approved tire types are modified, and the marking and documentation obligations must be maintained continuously across every market that accepts ECE approvals. A non-compliant E-mark is non-compliant everywhere simultaneously.
Each tire size and type designation requires a separate type approval submission. Changes to approved types - including compound modifications, construction changes, dimension variations and marking changes - must be assessed against the change notification requirements of the applicable regulation. Significant changes require a new type approval application and testing program; minor changes may be notified to the approving authority without re-testing.
The marking obligations for approved tires are specific and mandatory: the E-mark followed by the country code of the approving authority and the approval number must appear on the tire sidewall in the prescribed format. A tire carrying an incorrect or absent E-mark, or modified in ways constituting an unapproved change, is non-compliant in every market accepting ECE approvals - including the entire EU, UK, Japan, South Korea, Australia, Russia, Turkey, South Africa and numerous other markets.
UN ECE regulations are subject to amendment series (01, 02, 03 etc.), and the applicable amendment series version at the time of approval determines the test requirements. As new amendment series enter into force, manufacturers must assess whether existing approvals remain valid or require upgrade submissions. The transition period between amendment series creates compliance decisions about when to submit new approvals versus maintain coverage under older series approvals.
While the ECE regulations are international standards, each contracting party's implementation may include national variations in administrative procedures, technical service recognition, approval certificate formats, and additional country-specific requirements beyond the base ECE regulation. Japan, South Korea, Australia and several other contracting parties implement ECE-based approval systems with specific local administrative procedures that require jurisdiction-specific compliance management.
The OEM fitment context adds a further layer of complexity and commercial consequence to type approval management. Type approval deficiencies in OEM-supply tire sizes create not just a commercial supply problem but a whole-vehicle type approval deficiency that can delay vehicle launch - making type approval compliance a vehicle launch risk issue for OEM customers, not merely a regulatory compliance matter for the tire supplier.
An OEM vehicle manufacturer fitting a tire to a new model under whole vehicle type approval requires that the tire carry a valid R30, R54 or R75 approval - and specifically that the approval number appears in the vehicle's type approval documentation. An OEM customer discovering during a homologation audit that a supplier's tire lacks current type approval for a fitment size creates a whole-vehicle type approval deficiency that can delay vehicle launch.
OEM procurement processes for tire fitment typically include homologation audits at pre-series, series launch, and periodic surveillance intervals. These audits verify that the tire type approval number in the vehicle documentation corresponds to the current valid approval for the supplied tire, that the tire markings are correct, and that no unapproved changes have been made since the original approval. Radial Insights prepares manufacturers for these audits with compliance documentation packages.
For manufacturers supplying OEMs across multiple vehicle programmes in multiple countries, the type approval portfolio spans dozens of tire size and type combinations under multiple regulation versions. Managing this portfolio requires systematic tracking of approval expiry dates, amendment series applicability, and OEM vehicle programme timelines to avoid gaps in coverage that create vehicle launch risks.
Type approval requirements for replacement tires in the aftermarket differ from OEM fitment requirements in some jurisdictions - where aftermarket sales may proceed under different approval categories or with market surveillance rather than pre-market approval. Understanding the replacement market type approval requirements for each target market is essential for manufacturers selling both through OEM fitment and aftermarket distribution channels.
Radial Insights advises on test programme design to maximise the range of sizes and load/speed indices covered under a single type approval family, approval submission preparation and technical service liaison for homologation testing. Efficient test programme design minimizes the number of separate submissions required while achieving maximum portfolio coverage under each regulation.
We manage the type approval submission process - preparing the application documentation, coordinating with accredited technical services for test programme execution, and managing the approval certificate process with the designated national approval authority. For multi-country approval programmes, we manage simultaneous submissions across multiple contracting party jurisdictions.
We conduct sidewall marking compliance audits for existing product ranges to verify E-mark format, country code and approval number accuracy across production variants. We also design change assessment protocols to determine when product modifications require re-approval versus amendment notification, protecting manufacturers against inadvertent unapproved change violations.
For manufacturers managing multi-country type approval portfolios, we provide consolidated compliance calendar management covering renewal dates, standard revision implementation deadlines, and scheduled surveillance audit windows across all active certifications. This integrated portfolio view prevents compliance gaps that arise when individual approvals are managed in isolation without visibility of the full portfolio timing.
Radial Insights brings deep experience with UN ECE R30, R54 and R75 across test programme design, submission preparation, OEM homologation and ongoing portfolio management. Contact our team to discuss your type approval requirements.
