Product Details

The Nitto NT 421Q is a premier all-season tire engineered specifically for crossover utility vehicles (CUVs) and SUVs. This tire combines sophisticated design with advanced technology to deliver reliable performance, comfort, and safety throughout all seasons, whether you're facing rain, shine, or light snow conditions.

Advanced Traction Technologies:

  • Revolutionary 3D Multiwave Siping: Features 3D interlocking sipe design that provides exceptional wet and snow traction without compromising handling performance
  • Three Wide Circumferential Grooves: Deep grooves rapidly evacuate water for improved wet handling and hydroplaning resistance
  • High-Density Sipe Design: Inner tread area features increased siping for maximum biting edges in wet and winter conditions
  • Asymmetric Tread Pattern: Optimized design balances all-season performance with a quiet, comfortable ride

Enhanced Durability and Handling:

  • Circumferential Rubber Shoulder Inserts: Additional layer of reinforcement helps resist damage from potholes and adverse road conditions
  • Large Exterior Tread Blocks: Provide enhanced stability and confident cornering performance
  • Intelligent Maintenance Indicators: Visual wear indicators help you monitor tire condition and identify potential issues before they become serious problems
  • All-Season Rubber Compound: Specially formulated to maintain flexibility and grip across a wide temperature range

The NT 421Q's combination of advanced siping technology, water-evacuating groove design, and durable construction makes it an ideal choice for drivers who demand year-round performance and safety from their crossover or SUV tires.
