How scores work
- Relative score
- 0–100. Blends road tests (60%) and owner reviews (40%) category by category, the same way on every TireWheelGuide page. With only one of the two, the missing half is estimated from it, so the score stays closer to average. It needs at least one road test or five owner reviews.
- Road tests
- 0–100 per score, from published tests, newer tests counting more. Each result is compared with every other tire in the same test, so a win against a strong field counts for more. The average tested tire gets 70, the best 100; with only one or two tests a tire stays nearer 70. The discipline rows show % of the best tire in that test.
- Owner reviews
- 0–100 from the owner reviews we found online, adjusted for how generously each site rates and scaled like the road tests: the average tested tire gets 70. With only a few reviews a tire stays near the average.

The Nitto NT420s is widely praised by users for its exceptional dry and wet traction, responsive handling, and visually appealing tread pattern. While most reviewers highlight a smooth, quiet ride and high grip levels, a few note compromises in tread life due to the softer rubber compound and increased noise over time.
Pros
- Exceptional dry and wet traction with high grip levels
- Stylish and distinctive tread pattern design
- Smooth, quiet ride quality compared to stock or alternative options
- Strong handling performance suitable for trucks, SUVs, and performance cars
Cons
- Shorter tread life due to a softer rubber compound
- Tires can become noticeably noisier as mileage increases (after around 12,000 miles)
- Limited capability in heavy winter or snow conditions
Worth knowing
- Users running larger 20-inch, 22-inch, and 24-inch sizes on heavy luxury SUVs like the Cadillac Escalade noted a smooth ride, even on lowered setups.
- Drivers of muscle cars like the 2011 Chevrolet Camaro reported successfully using the tire for both daily commuting and track days at Willow Springs.
