The Diamond Back DR777 is a winter tyre designed for passenger cars during cold weather and snow conditions. The tyre features four deep longitudinal grooves cut in a zig-zag pattern connected to wide lateral sipes and numerous micro-sipes to ensure enhanced grip on snow and ice while efficiently evacuating water, mud, and slush. The central rib is grooved to enhance road holding and stability at high speeds. For wet conditions, the tyre carries a D grade wet grip rating, while dry tarmac performance is rated at class 2. Noise levels range from approximately 71 to 72 decibels depending on the specific size. The tyre carries speed ratings from T (up to 118 mph) to V depending on the size variant, and load indices vary from 86 to 98 based on the tyre dimensions selected.
