Key Features

  • Nitto’s intelligent maintenance indicators are a service feature that visually show how your tires are wearing. They can also alert you to wear issues before they become big problems.
  • Siping is one of the most important tire technologies for wet and snow traction. Nitto's revolutionary 3D multiwave and 3D Interlocking sipe design provide traction without sacrificing handling.
  • The circumferential rubber shoulder insert adds an additional layer of strength to help you navigate potholes and other adverse road conditions.
  • The NT421Q helps you safely navigate corners because the larger tread blocks on the exterior of the tire provide stability.
  • The NT421Q is an all-season tire that keeps you safely connected to the road in inclement weather. The three wide and deep circumferential grooves improve water evacuation, providing increased wet handling and traction.
  • The inside tread area of the the tire was designed for wet and winter weather performance. The large, open grooves provide lateral water evacuation while the high sipe density increases the number of biting edges contacting the road.
  • NT421Q is backed by a class-leading mileage warranty which covers 75,000-mile for H, V speed rated sizes, and 60,000-mile for W speed rated sizes.
