Nitto Tire has launched a new all-season tire, the NT421Q. This is Nitto's newest all-season ultra high performance tire for both CUVs and SUVs. It's available in 31 sizes, with three more in the near future. Its new design incorporates two advanced siping technologies that increase grip and tread-block rigidity under acceleration, braking and cornering conditions. The advanced tread compound also incorporates a new high-grip polymer. Specifically, a wear-oriented polymer and increased silica for better performance, safety and longevity.
A testament to the NT421Qs longevity comes backed by 75000 mile warranty for H and V speed-rated sizes, and 60000 for W speed-rated sizes. These tires are outfitted with Intelligent Maintenance indicators, which provide visual alerts for irregular wear and other potential issues with a vehicle's suspension and alignment.
