Tyres & Wheels

Tyre and wheel approvals verify safety, durability, performance, and marking compliance across categories, load/speed indices, and fitment combinations. Programs address strength and endurance, rolling resistance and noise, wet grip, bead retention, rim compatibility, and regulatory markings for market entry.

Evidence typically covers dimensional checks, load/speed testing, plunger and bead unseating resistance, rolling resistance, wet grip performance, exterior noise, and aging. Documentation must reflect tyre families, sizes, speed symbols, and rim fitment—plus labeling and traceability to Conformity of Production (CoP).

The International Automotive Federation (IAF) helps manufacturers structure families, plan verification, and prepare authority-ready technical files—reducing retest and accelerating approvals.

Understanding Tyre & Wheel Requirements

Approvals hinge on accurate category and family definition (tyre size, load/speed index, construction) and on rim compatibility. Regulatory markings, labeling, and documentation must match tested specifications and production status.

Performance & Endurance

Load/speed endurance, high-speed tests, bead unseating resistance, plunger energy, and aging checks.

Efficiency, Noise & Wet Grip

Rolling resistance for efficiency, exterior noise limits, and wet grip performance across sizes.

Dimensions, Markings & Labeling

Dimensional tolerances, load/speed symbol accuracy, labeling conformity, and production traceability.

Rim Compatibility & Wheel Integrity

Wheel/rim strength, fatigue tests, dimensional compatibility, mounting procedures, and corrosion checks.

How IAF Supports Tyre & Wheel Programs

IAF optimizes family definitions, schedules accredited tests, and prepares authority-ready dossiers.

Family Strategy & Evidence Matrices

Group sizes and constructions to minimize retest while preserving compliance integrity.

Accredited Lab Access & Scheduling

Performance, durability, noise, wet grip, and rolling resistance trials with recognized facilities.

Markings, Labels & Dossiers

Verification of markings/labels and preparation of localized submissions for authorities.

Lifecycle Compliance & CoP

Sampling plans, surveillance records, and change control to sustain approvals over time.

Streamline Tyre & Wheel Approvals

Plan families, book accredited tests, and submit complete dossiers with IAF support.
