Air Claw Technology refers to a special combination of a steel stud and air shock absorbers. It reduces road wear, dampens tyre noise and improves stud durability. The invention that has the greatest impact on the tyre's performance is similar to the heel cushioning in good running shoes. The air vents in the tyre soften and absorb the stud impact, making driving smooth and flexible. For the driver, the combination of anchor stud and air chamber, Air Claw Technology, offers superior comfort and uncompromised safety: uniquely smooth driving experience ensured by entirely new air chambers and the Eco Stud System familiar from the previous stud tyre.
