Nitto NT421Q Tires

  • Large outer tread blocks increase the amount of surface area in contact with the road, improving dry cornering and handling
  • Asymmetrical, non-directional tread pattern allows for cross-rotation, which reduces irregular wear
  • Siping across the tread pattern provides additional biting edges to help maintain traction in wet weather conditions
  • Center tread pattern effectively channels water for better wet weather performance
  • Slanted three-dimensional tread blocks reduce flex for improved handling

Overview

The NT421Q tire is specifically designed for crossover utility vehicles and SUVs. These tires provide premier, all-season performance and are designed to provide a smooth and quiet ride. Of course, this is not their only great feature.

The NT421Q tires are incredibly adept at handling both wet and dry conditions. Reviewer Jim Penn says, “In the rain, the tires handled very well. Wet road traction was very good, it held the road. As for the snow, the tires managed to grip going up the driveway…So far, my wife and I have been very pleased with the NT421Q tires in all conditions.”

Nitto, of course, creates this all-season performance by building their NT421Q's with advanced siping technologies, one of which is only typically found on high performing winter and snow tires. Also adding to the strength are unique rubber inserts that are placed in the shoulders of the tire. These help to provide balance and added sidewall strength, which add comfort and increased performance. Bottom line: the NT421Q is great for anybody that needs a strong, durable tire for their crossover utility or SUV.
