The NT421Q features advanced siping technologies, one of which is traditionally found only on dedicated winter/snow tires.The three-dimensional sipes lock together to increase tread block rigidity to aid all-weather traction while preventing unwanted flexing and irregular wear of the tread.

Nitto’s Quiet Serration Technology embedded in the groove of the tire reduces road noise to make each drive more quiet and comfortable. Much like the acoustics in a music hall or recording studio, this technology helps break up repetitive and reverberating noise. This along with the variable pitch tread blocks, generated through Nitto’s proprietary computer simulation process, creates a tire that delivers welcomed quietness.
