"three-ply sidewall and advanced silica compound for excellent durability and puncture resistance"

...eli samaa kumiseosta mitä yleensä käytetään vain kuvion puolella:

"The tyre uses a radical sidewall concept called DURAWALL. This takes the construction elements usually found in the tread area of the tyre into the sidewall area of the tyre. This includes a combination of polyester and a hybrid Silica compound to offer more tear strength and wear resistance, yet still retain its sidewall flex. The Silica compound delivers nearly three times more tear resistance than the conventional carbon black tyre material."
