The Bridgestone RE040 Potenza is an ultra-high performance summer tire made as the original equipment for a number of high performance sports cars and sports coupes. These tires are suitable for use on the likes of the Nissan 35OZ and the Acura NSX just to name two. The RE040 tire was created to provide drivers with good traction, predictable dry handling, responsiveness and great wet road handling. AS a summer tire these cannot be driven through snow or ice and cannot be driven on surfaces that are at temperatures close to freezing. The exterior of these tires features a high grip tread compound that has been molded into a directional tread design. There is also a continuous center rib along with large tread blocks that are rectangular in shape both of which help to provide high speed stability, responsive handling and traction on wet and dry roads. There are also the lateral and circumferential tread grooves that help to reduce hydroplaning by pushing the water away from the footprint of the tire thus improving the tires wet traction. On the interior of these tires there are two spirally wrapped steel belts that provide enhanced handling, enhanced ride quality, a stable tread area and increased high speed capability while minimizing weight. Internally you can also find hard rubber sidewall filler and a fabric cord body that blends uniform ride quality and steering response with lateral stability.
