The Delinte Thunder D7 is an ultra-high-performance all-season tire that's made for use on performance sedans, sports cars, and coupes. Offered in H-, V-, W-, and Y-speed ratings, the Thunder D7 provides high-speed performance and features a high-tech silica-based rubber compound for increased traction and maximum wear resistance. The tread pattern of this tire features four wide grooves that optimize water channeling for increased wet weather traction, and the D7's variable tread pitch sequencing reduces tread noise levels for a comfortable driving experience. Additionally, the D7 utilizes a solid center tread area that maximizes traction and reduces rolling resistance for increased fuel economy.
