With an estimated 460,000km lifespan, the tyre has been noted for its mileage durability on mixed roads, including high speed roads. Carrying stocks cargo and with a weight of 49 tonnes, the tyres proved durable with a wear rate of 35593 km per mm. In the words of RoadOne's customer, "it is very wear-resistant anti-eccentric wear is good. We have purchased this tyre many times and recommend it to colleagues."
With an optimised profile design, as well as a special fine pattern treatment and a specific 4 belt cap design the tyre balances steady grip on slippery roads with comfortable driving. With its optimised shoulder design the tyre has a reduced rolling resistance, whilst allows for multiple retreads in its lifetime.
The tyre is currently most popular on the 1F, 2D and 3ST wheel models. Due to its wear resistance and its fit on the tyre, the tyre proved to be popular on its test run with the driver.
