▪ Procedure and Evaluation
- In all tests, the control tire is tested repeatedly in the progress of the test to
detect and consider changes of the ambient test parameters and correct its performance by linear interpolation.
- Generally, all tires in a test are primarily evaluated in relation to the control tire.
- The performance is expressed as a percentage value, calculated on the basis of the measured and corrected test data.
- In this present evaluation, the performance of each tire is assessed relative to the reference tire (Dunlop ≙ 100%).
- In all evaluations, a percentage value >100% means better and <100% means worse.
