The Proxes R40 features a non-directional asymmetric tread pattern with minimal shoulder grooves that maximize dry traction and cornering stability, while circumferential channels efficiently disperse water for reliable wet handling. Reinforced outer blocks enhance lateral grip during maneuvers, and the silica-infused compound maintains flexibility in high temperatures for consistent performance. Variable pitch sequencing curbs road noise for refined comfort, and the radial casing with steel belts supports loads up to 630 kg without deformation. Optimized contact patch promotes even wear and responsive steering at V speeds (149 mph).
