Yokohama Advan Apex V601 The Yokohama ADVAN Apex V601 is a Y-rated ultra-high performance street tire designed to redefine grip and dominate U.S. roads. Available in today's popular bigger sizes for a bigger dose of performance on the street, this is a tire that doesn't just demand respect, it's earned it. For precise handling, a strong sidewall with an ultra-high turn up and hard bead filler delivers immediate cornering response, while an uninterrupted solid center rib enhances high speed stability. Maximum grip is provided by a competition-inspired tread design and an advanced compound with high-grade micro silica for confident multi-surface grip, which is supported by 3+1 circumferential grooves where three inside grooves enhance wet performance and a narrow outside groove dissipates heat for optimal dry performance. To ensure a quiet ride, the rigid construction and noise optimized tread grooves with optimized angles minimize road noise. Finally, long tread life is achieved through an advanced micro-silica compound combined with a rounded rib design that optimizes pressure across the contact patch and reduces uneven wear.
