The Sonix SX668 is a premium-tier, all-position radial tyre, though it is primarily engineered for the steer axle of heavy-duty commercial vehicles. It is designed specifically for long-haul and regional transport applications where durability and high load capacity are paramount.
The SX668 features a sophisticated five-rib tread design that promotes exceptional directional stability and precise steering response. Built with an enhanced 20-ply (20PR) carcass, this tyre offers superior structural integrity and a higher load-carrying threshold compared to standard 18-ply alternatives. The tread compound is formulated to dissipate heat efficiently during sustained high-speed highway operations, while the deep longitudinal grooves provide excellent hydroplaning resistance. With a focus on even pressure distribution, the SX668 minimizes irregular wear, ensuring a longer service life and high retreadability for fleet operators.
