Nitto NT421Q All-Season Touring Tire
Choose confident year-round driving with the Nitto NT421Q. This touring all-season tire balances stable dry handling, dependable wet traction, and a quiet, comfortable ride. A silica-enhanced cold-weather compound stays pliable as temperatures drop, and the asymmetric tread with dense siping helps braking and control in rain and light snow. Continuous ribs steady straight-line tracking, while variable-pitch blocks help hush highway noise so daily commutes feel smooth from the first mile.
Key Features of the Nitto NT421Q
The NT421Q is tuned for everyday comfort and control. Larger outer shoulder blocks boost cornering confidence and on-center feel, and wide circumferential grooves move water to resist hydroplaning. A cold-weather compound stays flexible for consistent all-season traction, while extensive siping adds wet and light-snow bite. Reinforced construction promotes even wear and highway stability, and multi-pitch sequencing helps keep pattern noise in check.
On‑Road Performance: Dry, Wet, and Light Snow
On dry pavement, the NT421Q feels composed and secure, with responsive shoulders that keep steering precise through lane changes and ramps. In rain, broad grooves and dense siping clear water to support confident braking and cornering. Light snow traction is usable for everyday dustings, though frequent deep snow or long stretches of ice call for dedicated winter tires. Ride quality stands out, with a stable center rib that tracks straight and reduces cabin noise on long highway drives.
Sizes, Fitment & Care
Find popular NT421Q fitments such as 265/60R18, 265/50R20, 255/50R20, and 285/45R22. Match tire size, load index, and speed rating to your door-jamb label or owner's manual for safe handling. Rotate every 5,000 to 7,500 miles, maintain recommended pressures, and follow vehicle-specific patterns if you run staggered sizes. Professional mounting and road-force balancing can further enhance ride quality and tread life.
Is the NT421Q directional?
No. The NT421Q uses a non-directional, asymmetric tread pattern. That means same-size sets can typically be cross-rotated, front to back and side to side, to even out wear. Always mount the inside and outside sidewalls in the correct orientation, and follow your vehicle's rotation guidance when using staggered sizes or unique offsets.
Price, Warranty & Value
The NT421Q is priced to deliver strong all-season value with refined ride quality and durable tread life. Exact pricing varies by size and specification, so check current promotions for the best deal. The tire includes a limited treadwear warranty, with mileage coverage that differs by size and speed rating. Add optional road-hazard protection for extra peace of mind, then choose fast shipping or a local install at checkout.
Customer Reviews & Real‑World Feedback
Owners often highlight the NT421Q's quiet, composed highway manners and predictable behavior in daily commuting. Wet traction feels balanced, with stable steering that suits larger vehicles. Treadwear holds up well when rotations and tire pressures stay on schedule. In winter, drivers report solid performance in light snow and recommend dedicated winter tires for deep snow or prolonged ice.
Nitto NT421Q vs Nitto NT420V
Both the NT421Q and NT420V are all-season designs, but they target different priorities. The NT421Q focuses on touring comfort, a quiet ride, and even wear for daily driving and long highway trips. The NT420V delivers a sportier feel and a firmer, more responsive character. If refined comfort and tread longevity top your list, choose the NT421Q, and always select the correct size, load, and speed rating for your vehicle.
