Nitto NT421Q is an all-season tire developed and designed with advanced sipping technologies feature which helps you reach your destination safely even if it is rain, shine or light snow condition. It has Nitto's 3D Interlocking sipe design and revolutionary 3D multi-wave providing traction without giving up handling.

Combining all of these sipes, all-season rubber compound and circumferential grooves that expels water will allow SUVs and crossovers to thrive throughout the seasons.  This has large and open grooves providing an improved lateral water expulsion with the help of its deep and three wide circumferential grooves while increasing wet handling and traction and the number of biting edges because of its high sipe density. The tire’s inside tread area was designed for winter and wet weather performance.  It also offers stability due to the larger tread blocks exterior of the tire while you navigate corners safely. It has an added circumferential rubber shoulder insert for potholes and adverse road navigation. You can also get an alert for wear issues before the problem gets bigger due to its intelligent maintenance indicators, a service feature of Nitto’s that displays the wearing of your tires.

Sidewall BSW
This describes the sidewall appearance. Examples include Black Sidewall, White Sidewall, and White Letters.
Load Index 105
The load index (LI) is a 2 or 3 digit number that corrolates to the maximum amount of weight the tire can carry. For example, a tire with a load index of 87 indicates that the tire can carry a maximim load of 1,201 lbs. In the case of our example the 87 identifies the tires ability to carry a maximum of 1,201 lbs. So 4 tires will carry a maximum of 4,804 lbs. Refer to your vehicle owner's manual for the recommended minimim Load Index. It is not recommended to install tires with a lower Load Index. By doing so, this could cause your tires to be overloaded thus potentially causing a blowout.
Speed Rating V
Speed Ratings (SR) are based on laboratory tests and indicates the maximum speed the tire can achieve. These tests are based on limited time trials. Higher speed rating tires typically will yield better handling capabilities, but may often result in lower mileage. Refer to your vehicle owner's manual for the recommended minimum Speed Rating. It is not recommended to install a tire with a lower speed rating as it could affect the handling of your vehicle. It is important to note that speed ratings only apply to tires that have not been damaged, altered, under-inflated or overloaded. Additionally, most tire manufacturers maintain that a tire that has been cut or punctured no longer retains the tire manufacturer's original speed rating, even after being repaired because the tire manufacturer can't control the quality of the repair.
Ply Rating Not Available
Ply Rating is related to the max load capacity. This value can be defined with a letter or number. The higher the number/letter, the higher the load capacity.
To help consumers evaluate their tires, the U.S. National Highway Traffic Safety Administration (NHTSA) created the Uniform Tire Quality Grading System (UTQG). The UTQG rates tires are rated on their tread-wear, traction performance, and temperature resistance. The grade for each of these can be found on the sidewall of your tire (except for winter tires and certain light truck tires). Click here for more information.
Max Single Load(lbs) 2039 The maximum load this tire will support. Remember to multiply this number by the number of tires installed on your vehicle to get the maximum carrying capacity. This number is directly related to the Load Index.
Max Single Air Pressure(PSI) 50 The maximum air pressure this tire will support. This does not represent the amount of air pressure your tires should have at all times. Consult with your owner's manual to determine the best air pressure you should use for your vehicle.
Tread Depth 12.0 The amount of tread on the tire. Once the tire is worn to 2/32nds, it is considered fully used and should be replaced at that time. Most tires will have tire indicators in the grooves of the tire to help you determine when the tires are worn down to 2/32nds.
Rim Width Range 7.0-8.5 The approved wheel rim width range this tire will support.
Measured Rim Width 7.5 The recommended wheel width as recommended by the tire manufacturer to get the best wear us performance for this tire.
Section Width 9.96 The measurement from sidewall to sidewall.
Tread Width Not Available The measurement from one side of the tread to the other side of the tread.
Overall Diameter 29.69 The height of the tire when fully inflated.
