The Nitto NT421Q is a premium all-season tire engineered for modern crossovers, SUVs, and luxury trucks that demand whisper-quiet comfort, confident year-round traction, and refined highway manners—without sacrificing bold, aggressive styling.
Designed with Nitto’s advanced Intelligent Maintenance Indicators and Silent Wall Technology, the NT421Q delivers an ultra-smooth, library-quiet ride even at 80+ mph. Its asymmetric, non-directional tread pattern features large, stable shoulder blocks for precise cornering response and wide circumferential grooves that evacuate water efficiently to resist hydroplanining. The high-silica, low-modulus compound stays pliable in cold temperatures while resisting heat buildup during long hauls, ensuring consistent grip from freezing mornings to scorching summer afternoons.
Whether you're commuting in rain-soaked city traffic, towing on the interstate, or carving winding backroads, the NT421Q provides predictable handling, short wet/dry braking distances, and exceptional treadwear—all wrapped in a sleek, dual-sidewall design that lets you choose between a sophisticated or aggressive aesthetic.
This is all-season performance, redefined—luxury meets capability.Detailed Specifications:
