About This Tire

The Radar Dimax AS-8 255/55R20 is a grand touring all-season tire designed for drivers of performance sedans, sporty coupes, crossovers, and SUVs who prioritize fuel efficiency and ride comfort in everyday driving. Its asymmetric tread design and silica-enriched compound focus on delivering balanced traction across wet and dry conditions while maintaining long-term durability.

The tire features circumferential grooves and independent tread blocks for hydroplaning resistance, while a continuous center rib promotes highway stability and reduces road noise. Wide-distribution lateral sipes across the tread provide grip in wet, slushy, and light snow conditions, and the rounder shoulder design delivers progressive cornering response. Driver feedback points to strong wet and dry performance, with comfortable ride quality and reliable treadwear standing out in daily use.

Compared to performance-oriented tires, it emphasizes comfort, stability, and long-term usability. Overall, it's a solid choice for crossovers and SUVs used primarily for highway commuting and family transportation in varied weather conditions.
