The tire performance evaluation system is based on Tuhu’s insight into consumers’ individual needs, standardizing evaluation rules and establishing the weights of various performance evaluation indicators to ensure that the evaluation results are professional and fair.
The evaluation standards and test methods refer to the test methods of international standards, national standards, industry standards and other professional institutions, and all test items are completed by a number of evaluators in several domestic real vehicle test sites and national laboratories:
In the real vehicle field test scenario, such as the measurement of braking distance in dry and wet conditions, strict regulations are made on environmental variables such as test road temperature, wind speed and water film thickness, which are close to the real scene of consumers using tires.
In the "sturdy" performance test, considering that the vehicle bulge is mostly caused by sidewall collision, the test section simulates the collision between daily urban driving and the road shoulder, and a 45-degree impact test is designed.
The noise road and the noise and vibration test road (NVH road) in the real vehicle test site have a variety of road surfaces to restore the road conditions in daily driving, such as smooth asphalt road, rough asphalt road, concrete road, washboard road, step road, protruding road, etc. Make the evaluation results of comfort and quietness more comprehensive.
For the "handling" performance, a number of professional drivers evaluated the stability of straight driving, steering performance, braking stability, grip, water drift and other driving conditions on dry, wet handling roads and wet circular roads.
To be clear, the testing standards are very strict.
