The report presents an investigation of test vehicle influence on the results of tire/road noise measurements. The experiments were conducted by testing the same set of tires on four different, compact cars and another set of tires on four bigger cars. The cars were selected to be different in age, condition, type, etc. Despite a great variation in car type and construction the differences of the measured A-weighted sound levels were very small. Some interesting differences in noise spectra were, however, noticed for cars of unusual construction and/or in slightly impaired condition.
