Kumho Tires Ecsta PS91 235/40R18 95Y XL BSW

Cars rarely get to experience the research and development that goes into creating formula one tires. The Ecsta PS91 flips the script on that, offering drivers a unique experience in a tire that derives from Kumho's motorsport traditions. Sporting "F3" racing technology, this tire is designed for performance sports cars and luxury vehicles that offer adrenaline-pumping speed. The compound used to create the tire is a carbon black and silica compound that combines with the tread pattern to give better traction on the road surface. It's an all-season tire, offering great wet and dry handling - not something you usually find in ultra-high performance tires. Part of this special handling comes from the continuous center rib and its stiffer tread blocks. This construction allows the tire to have added responsiveness while allowing for stability at the high speeds it's likely to be used. Kumho's patented 3D Dimple Design cools the tread blocks, ensuring there's a low chance of a structural collapse. The four circumferential grooves and wide lateral grooves provide the best opportunity to extricate water from in front of the tread. Hydroplaning is a serious concern at high speeds, but these advancements keep the tire in constant contact with the road, reducing that risk. Looking for an ultra-high performance tire that works well in all seasons and road conditions? You might have struck gold with the Ecsta PS91.
