The Potenza RE040 is an Ultra High Performance Summer Original Equipment tire designed to complement the performance of sports coupes and sports cars including the Acura NSX, Audi TT, BMW 3-Series, Lexus SC430, Nissan 350Z and Toyota MR2. The Potenza RE040 was developed to provide good traction along with responsive and predictable dry and wet road handling. It is not intended to be driven in the snow.
On the outside, the Potenza RE040 features a high grip tread compound molded into a subtly directional tread design. A continuous center rib and large rectangular tread blocks provide responsive handling, high-speed stability and traction on dry roads, while circumferential and lateral tread grooves are aimed to pump water out from under the tire's footprint to minimize hydroplaning and aid wet traction. Internally, the Potenza RE040 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 fabric cord body and hard rubber sidewall filler helps blend uniform ride quality with steering response and lateral stability.
Bridgestone Potenza RE040 tires feature black sidewall styling with subtle black letters. They are V-, Z, W- and Y-speed rated depending upon their application and available in 55-, 50-, 45- and 40-series sizes for 15" through 18" wheel diameters.
