Product Description

ULTIMAT EYE is the Bridgestone own tire development technology to measure, predict and visualize the ground surface behavior of the tire. Conventional tire development, a simulation, to make a prototype, has been done in the flow of the performance confirmation through the indoor measurement and the actual vehicle test. ULTIMAT EYETM is, to reproduce the high-speed running state equivalent to that of the vehicle in a room, you can visualize the behavior in the tire ground plane. Thus, in addition to the conventional vehicle testing, high analysis and performance check accuracy based on scientific grounds can be performed, it is possible to further improve the performance of the tire. It should be noted that the testing machine to perform this measurement and analysis, can accommodate up to a speed of 400km, bank angle of 60 degrees.

By diameter of the crown portion of the front tire, the tire contact patch in an inclined state of the vehicle during cornering becomes long in the vehicle longitudinal direction, which the force turning the vehicle (camber thrust) is increased, the conventional product ” BATTLAX HYPERSPORT S20EVO “have contributed to the improvement of the cornering performance in comparison.

Review the compound designed from the molecular level, it has developed a new compound that improves the tire and the road surface of the ground of at the micro level. This new compound, which is important when cornering, front (divided into three tread) and the rear tire (5 split tread) ※ adopted in two of the shoulder part, we are contributing to the improvement of the cornering performance.

By leveraging ULTIMAT EYE ™ to the structural design of the rear tire, so far of the tire can be grasped in detail the behavior to slip the road surface of the ground surface that was not visible in the analysis technology, that reduces the sliding region greatly It was successful. Thereby wear is reduced, achieving a wear life improvement of about 30 percent.
