The Nitto NT421Q is a premier all-season touring and performance tire engineered specifically for crossovers (CUVs) and SUVs.
Safety is a key element to this tire, which utilizes a stylish, unique asymmetric tread design for a quiet, comfortable ride and dependable all-season traction.
The variable pitch tread design reduces road noises for both passenger and driver comfort.
Nitto equipped this tire with intelligent maintenance indicators, which show how your tires are wearing and to alert you before any issues arise.
For wet and snowy traction, the NT421Q has 3D multiwave and 3D interlocking siping that provide powerful grip without sacrificing handling.
This tire uses three wide and deep circumferential grooves to enhance water evacuation, giving you serious control during the rainy season.
Large open grooves pair nicely with the high sipe density, providing water evacuation and extra bite for grip in water and light snow.
Additional shoulder inserts buff up this tire’s strength levels, helping you overcome potholes and other road hazards.
Large outer tread blocks provide steering response and control in fast corners.
This tire fits wheel diameters between 17-22”, so it fits a wide range of vehicles.
The NT421Q comes with a range of 10-13/32” tread depth for long lasting tread life, traction and wear, giving you the most bang for your buck.
Nitto ensures this premier all-season tire with up to a 75,000-mile warranty to give you peace of mind with your tire purchase.

Great all around tire on 2006 Ford Explorer.
Rainier
They seem to be wearing very well, smooth and quiet. Only time will tell how they do over time. We don't drive the car like most people do. Mostly around town and the occasional road trip. About 8,000 per year. At this rate I suspect that they will dry out before the tread wears out. 5 stars so far!
