Smooth and Quiet

Smooth and Quiet
Quiet Serration Technology imbedded in the groove of the tire reduces road noise to make each drive more quiet and comfortable. Much like the acoustics in a music hall or recording studio, this technology helps break up repetitive and reverberating noise

Intelligent Maintenance Indicators

Intelligent Maintenance Indicators
Nitto’s intelligent maintenance indicators are a service feature that visually shows 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 provides traction without sacrificing handling.

Added Shoulder Inserts

Added Shoulder Inserts
The circumferential rubber shoulder insert adds an additional layer of strength to help you navigate potholes and other adverse road conditions.

Tread Block Stability

Tread Block Stability
Thanks to larger tread blocks on the exterior of the tire, the NT421Q helps you safely navigate corners.

Wet Traction

Wet Traction
The NT421Q is an all-season tire that keeps you safely connected to the road in inclement weather. Its three wide and deep circumferential grooves improve water evacuation, and provide increased wet handling and traction.

Winter Performance

Winter Performance
The inside tread area of 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.

By incorporating computer-modeled designs for road noise reduction and a program that aids in enhancing dynamic contact points while driving, Nitto's engineers successfully identify and counteract undesirable responses of the tires in a variety of driving conditions. In addition, the tested technological advances in polymer tread compounds allow their engineers to deliver truly high-quality Nitto tires that provide extended tread life, improved traction on both wet and dry roads and inspire driver satisfaction.

Founded in 1979, Nitto® is driven by passion and innovation. They create tires for those who are enthusiastic about their vehicles. The company always strives to anticipate and drive consumer trends by supporting emerging markets before they are mainstream, helping them grow and driving the market forward. Nitto's tire sizing, tread patterns and tire compounds combine modern aesthetics with cutting-edge technology. This philosophy has helped them create some of the most radical-looking tire designs available on the market today. These memorable designs are the result of state-of-the-art development, quality engineering and rigorous testing procedures.

Surprising Traction and Handling Response for Dodge Charger R/T AWD. A New Customer for Nitto
Originally my car was running Goodyears just because they were a brand the family has been running (including myself) for years. But this past summer season was coming to an end and along with it a tire change. I was planning on going with the tried and true again until one friend mentioned I should try some different tire brands out to see how they compare. So I parked the car in the garage and started on my journey to research for the best tires that would fit my driving style. From Falken to Toyo, Continental to Michelin, I found any information on the companies that I could. Then I found out about Nitto Tires, a branch company of Toyo (independently running from Toyo). They got their foothold by going to competitors & attending car enthusiast and asking what they wanted from a tire. Through listening to the intended customers, they honed their tires to meet these expectations. So I decided to give them a try and I have to say it was an amazing decision. Right in the beginning i noticed that i didnt have as much slip as what I used to have from Goodyear. So I put another 1000 miles on the tires to see if there would be any fade in the grip. To my surprise, I didn't feel any initial drop off. I was able to take corners a little faster, the rear end didn't want to step out from behind as often, and no spinning the rear wheels on take off. In summary, if you are looking for a new tire brand to try out for you project car, muscle car, or any performance oriented daily driver, the best suggestion would be to try some Nitto's.

1. What is the tread depth? 2. How do they compare on 'quiet running' scale?
Posted by walter / October 14, 20222017 Cadillac XT5
CARiD Answer:
Hello, the tread depth for the sizes that will fit your Cadillac are listed as 12/32. As for the noise, there is no dB scale for tires. Noise will vary based on vehicle weight and road surface. Being an all-season highway tread however, these will be on the less-noisy side of tires.
