Confidence Through Any Weather No matter if it is rain, shine, or even light snow, the NT421Q™ helps your customers arrive safely at their destination. Siping The NT421Q includes 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. Smooth and Quiet Nitto’s Quiet Serration Technology imbedded 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 provides welcomed quietness. 3 GROOVES 3 wide grooves help evacuate water for added traction during inclement weather. Intelligent Maintenance Indicators The easy-to-read wear indicators shows how the tires are wearing and can provide an early alert for irregular wear. The indicator marks placed within all three circumferential grooves of the tire points out signs of irregular wear and possible issues with the vehicle’s alignment. Dependable Performance The NT421Q includes unique rubber inserts in the shoulders of the tires to provide a balance of added sidewall strength and smooth ride comfort. *By request/order.
