On the outside, the Potenza RE030 features a high-grip tread compound molded into a symmetric tread design. The Potenza RE030 features two continuous center ribs along with large intermediate and shoulder blocks to provide responsive handling, high-speed stability and traction on dry roads, while circumferential and lateral tread grooves are aimed to channel water out from under the tire's footprint to reduce hydroplaning and aid wet traction. Internally, the Potenza RE030 features twin steel belts reinforced by spiral-wrapped nylon to stabilize the tread area and enhance handling, high-speed capability and ride quality while minimizing weight. The rayon cord body and hard rubber sidewall filler helps blend uniform ride quality with steering response and lateral stability.
