Welcome into the World of Westlake
June, 2017—ZC Rubber has tested Westlake AD713 315/80R22.5 on the trucks and received a good result on the high mileage and wear-resisting during the one-year driving.
The tests started from April 2016 to March 2017. The fleet selected not only the Westlake tires but also an international tire brand A and a Chinese tire brand B. They were equipped in different positions of the trailers to get the survey information.
TRUCK 1
The test tires were equipped by Wamatha Truck 144.
Tread depth: Westlake AD713 22.5 mm and competitor A 20.2mm
The competitor A managed to achieve 6181,5 km/mm of thread depth and travelled 100 141 km when they had to be removed because the tread depth left was only 4mm.
The Westlake AD713 tires travelled 108 004km when they had to be removed because the tires were severely damage by driving them in the flat condition after a puncture. If the tyres were not damaged and used until a thread depth of 4mm the total possible km travelled is calculated to be 146 206km using the average km's/mm of 8385,8.
TRUCK 2
The test tires were equipped by LudekeTransport -Truck 80
Tread depth: Westlake AD713 21.5mm and competitor B 22.5mm.
The Westlake AD713 tires managed to achieve 10263km/mm of tread depth and the Chinese tire brand B managed to achieve 8079km/mm of tread depth at the last survey on 25 March 2017.
Since the last survey the B tires were removed because they reached the minimum allowable tread depth and the Westlake tires still had allowable tread depth left. According to the odometer reading, brand B’s total possible kilometers is calculated as 149 461km and Westlake’s total possible kilometers is calculated as 179 603km.
