Nitto 210790 NT421Q 235/55R19 105W XL All-Season CUV SUV Tire

The Nitto NT421Q is a premier all-season tire engineered specifically for crossover utility vehicles (CUVs) and SUVs. Built around a stylish asymmetric tread design, the NT421Q delivers a quiet, comfortable ride without compromising all-season traction or tread life. With a 60,000-mile treadwear warranty and a UTQG rating of 560 A A, it offers a compelling combination of performance and long-term value.

Key Features:

• Asymmetric Tread Design – The unique tread pattern provides a quiet and comfortable ride while optimizing dry and wet grip across all seasons.
• 3D Multiwave & 3D Interlocking Sipes – Advanced siping technology—typically found only on dedicated winter/snow tires—locks tread blocks together for rigidity during braking and cornering, while adding critical biting edges for wet and light snow traction.
• Three Wide Circumferential Grooves – Deep, wide channels efficiently evacuate water away from the contact patch, improving wet handling and reducing hydroplaning risk.
• High Sipe Density Inner Tread – The inside tread zone is tuned for wet and winter weather, using large open lateral grooves combined with densely siped tread blocks to maximize edge contact with the road.
• Circumferential Shoulder Inserts – Rubber inserts in the shoulder area provide added sidewall strength to help absorb impacts from potholes and road hazards while maintaining ride comfort.
• Large Outer Tread Blocks – Wider exterior tread blocks increase the contact surface area during cornering, improving lateral stability and confident steering response.
• Intelligent Maintenance Indicators – Visual wear indicators alert drivers to tread wear patterns before they develop into serious issues, helping maintain safe tire performance over the life of the tire.
• Variable Tread Pitch Design – Reduces harmonic road noise for a noticeably quieter cabin experience.
• XL (Extra Load) Rated – Load Range XL with a load index of 105, supporting up to 2,039 lbs per tire at maximum inflation.

The NT421Q carries a UTQG rating of 560 A A (Treadwear 560, Traction A, Temperature A) and is backed by Nitto's workmanship and materials warranty. Sold individually.
