Tire-road noise has become a research focus in vehicle acoustics research, driven by technical and regulatory factors, namely electrification and the continuously stricter exterior noise limits. Both factors increase the contribution of tire-road noise to the overall level as e.g. heavier vehicles with wider tires contribute to increased tire-road noise. Tire-road noise is influenced by both tire-specific parameters, such as tire dimensions, and vehicle-dependent factors like inflation pressure and wheel load. Parameter investigation through full-vehicle testing is complex and costly. Tire test rigs offer a more controllable and cost-efficient alternative for examination with high reproducibility. However, differences in the testing environments, such as variations in the tire contact patch and road surface, present challenges for accurately replicating real-world scenarios.This study introduces a methodical investigation of the influence of tire and vehicle parameters on tire-road noise through CPX adapted near-field measurements on an improved tire test rig. To ensure the validity of the drum test results, verification tests were conducted using a full vehicle setup. Real road textures were integrated into the drum surface to better simulate real-world driving conditions and minimize discrepancies between the two environments. The study also discusses the impact of these drum adaptations on measurement accuracy.
