Abstract: In view of the phenomenon of inner tread wear and outer shoulder wear of the front wheel of McPherson structure front suspension in the assessment of strengthened durable pavement, the paper analyzes the tyre factors, the stability of four-wheel positioning and the K&C characteristics of suspension. At the same time, with the aid of analytical data collected by means of load spectrum in real vehicle endurance condition, it is concluded that the mechanism of abnormal wear of the front wheel of the suspension structure appears under the condition of enhanced durability. And through the verification of special tire wear test, the rationality of the front wheel inner wear trend under this working condition is expounded, which provides a theoretical basis and analytical method for tire wear verification under the condition of enhanced endurance of similar vehicles.
