Rated 5 out of 5 by from Great overall performance and stability Very nice tire. Inexpensive compared to other brands at same size. These are on a Ram 1500 Daytona 4x4 with 22x10 SRT-10 wheels. Size 305/45/22. Mixed city and highway driving. Truck is very confident at 75mph on parkways with curves. Minimal noise, excellent wet and dry traction. Used in a blizzard with 2ft of snow. Handled it ok for an all season. Issues I had in the snow were a drifting sensation going straight and pushing through turns. The truck would sometimes try to slide straight. Just be very careful with the handling properties in snow. It took me a little bit to learn how to handle them.

Rated 5 out of 5 by from Best Sport Truck Tires!! 285/45/22 I Love these Tires!!! I was astounded at how quiet they are and how long they have lasted. I will state my only con that I have first, that is they flat spot after 2 days of sitting on my drive way and take about 5 minutes of driving to level back out( which I expect form such a large low profile tire). Besides that let's get how amazed I am with these tires. I remember the days when big tires did good to have 30k miles on them. I have @ least 30-40% of tread left & am pushing 55k miles so far. Not only do they handle rain like a Champ(Florida Boy...it rains every day), and keep my truck planted rain or shine....I had them on in PA last winter during some of the winter storms. I shocked all of my family that lives there with how well they handle even the snow storms, surprised myself too. Definitely will be the only tire I ever put on this truck, and plan to switch my wife's Lincoln Sport Ute over to a set of 421q's when the time comes. Great Job Nitto for making an amazing tire!!

Rated 5 out of 5 by from I love my Nitto Tires! I just want you to know that I really LOVE my tires. I'm a girl and not supposed to care about tires, but I DO! I mean, I didn't realize that I loved my tires until yesterday. I originally got my Nitto Tires in Texas before I moved back to my small town. It is time for new tires because I ran too much air in 2 of them…so, they wore out in the middle. Lesson Learned! Anyways, I bought a set of Bridgestones and I was so disappointed. I took them back immediately this morning and ordered a set of the Nitto Tires. The good news is…I know exactly what tire I want and won't have to go through that again. Just wanted to say, Thanks! Kindly, Shelly Spradling

Rated 5 out of 5 by from The 420S I will never buy any other tire for my truck. Not only does it handle amazing but it just rides phenomenal. Price point on them is perfect. No complaints at all. I would HIGHLY recommend these tires. They are like nicotine, once you try them..you'll be hooked forever!

Rated 4 out of 5 by from Drives great! It's hard to find a GOOD set of 285/45R22's for less than 1k. That said, these tires ride so smooth and confident on the road, rain or shine. The tread pattern is truly unique, so it sets my truck apart from the others. The tread is deeper than I expected as well. Looks like I'll have these for a while. My only minor complaint is the road noise. I had read reviews from other customers, and a few people did mention road noise, but most didn't. I can confirm that there is a slight humming noise at higher speeds, but the radio drowns it out. It's definitely there, but minor. The comfort and overall performance more than makes this tire worth every penny.

Rated 4 out of 5 by from Smooth and stable as long as the road is dry These are supposed to be an all-season tire, but they are horrible in snow, and hydroplane very easily if there is any standing water on the road. That's especially scary when pulling a trailer. If I lived in a wet climate I would get rid of them. In all fairness though, mine is a fairly wide tire on a 20" wheel (though it is the OEM factory size) and that probably does not help the wet weather performance. That's really my only complaint. They do generate a little road noise, but balanced well and do not vibrate at all, which is very important to me. They seem to be wearing very well, but I will probably go for more of a truck tire on this SUV next time around.

Rated 5 out of 5 by from 2 sets, 2 performance trucks and quite happy I have 2 performance trucks, one is a cammed/nitrous 2007 Ram 1500 4wd with a 2/4 drop, the other is a 2009 Ram 1500 Sport 4wd with a 392 stroker with a D1SC supercharger @15psi and a 175 shot of nitrous dropped 4/6. I push both trucks hard and I have been very happy with the performance of the NT420S both in 265/40R22. The '07 is still on its first set of 420s at 65,000kms and the '09 cooked a set off in 45,000kms and will be replaced with a set of 285/40R22s. I'm having trouble finding rubber that will plant a 30" tire with 640ft-lb short of my drag radials but for highly aggressive daily driving they are great. Both trucks have seen the drag strip on my street tires and if you roll into the launch they handle it quite well but they're not a drag radial by any means so I don't expect a low 60ft. They handle my top speed runs very well with the '09 peaking at 273km/h. I have autocrossed my '07 with these and the soft side wall does allow the tire to roll over a bit in the very aggressive turns. Living in Canada I've left my wheels on a little too long and got them into the first couple of snow falls and these tires are OK in snow by which I mean I can get around in 4wd and not get stuck until I get my snow tires put on. I wouldn't leave them on all year if you normally expect snow but they will handle the occasional snow with confidence. On the rare occasion I do tow with these trucks I can get a respectable weight in the bed/on the hitch and with the helper bags it's the tires that take the weight. They are a soft sidewall which means they will bulge quite a bit when loaded and that's the only downside I've found with them.

Rated 5 out of 5 by from Hook good I have had these tires for about a year now. They have about 15,000 miles on them and they are about half tread or a little less. They would have more tread but I like to do burnouts. Regular driving they are great. Quiet and they are wearing even. On asphalt they hook really hard. Doing a 4x4 boosted launch you can see the tire gripping on the pavement. They do really well with wet roads to. I have to really push my truck to make them spin. Only downside is if you like to do burnouts or donuts they wear really fast.

MSPN: NIT202-060R
Features:
  • Dry Performance
  • Siping
  • Tire Stability
  • Even Wear
  • Innser Shoulder Block Siping
Benefits:
  • The large outer tread blocks on the 420S high-performance tire increase the amount of surface area in contact with the road. This improves dry cornering and handling.
  • Siping across the tread pattern provides additional biting edges to help maintain traction in wet weather conditions.
  • Slanted three-dimensional tread blocks reduce flex for improved handling.
  • The asymmetrical, non-directional tread pattern allows for cross-rotation, which reduces irregular wear. *Consult your tire retailer on the appropriate rotation pattern for your vehicle.
  • Cut through the thin film of water on the road surface. This optimizes wet traction.

Speed Rating:

The speed rating is a measure of what speed the tire can safely maintain for sustained periods of time. A higher speed rating will generally indicate that you will have better control and handling characteristics. Speed rating standards are established by the U.S. Department of Transportation (DOT). Manufacturers assign speed ratings to tires after extensive performance testing. On the sidewall of every tire, you’ll find one of these speed rating codes:

M – Up to 81 mph
N – Up to 87 mph
P – Up to 93 mph
Q – Up to 99 mph
R – Up to 106 mph
S – Up to 112 mph
T – Up to 118 mph
H – Up to 130 mph
V – Up to 149 mph
W – Up to 168 mph
Y – Up to 186 mph
Z – (See Below)

What does ‘Up to 99 mph’ really mean?
Tires with a Q speed rating can safely sustain speeds of up to 99 miles per hour. The tire may be able to reach higher speeds, but traveling at speeds higher than 99 mph for any length of time would be unsafe - the tire is not designed to handle it.

What is a Z Rating?
For tires having a maximum speed capability above 149 mph, a Z rating may appear in the size designation ...above 186 mph, a Z rating must appear in the size designation, including a Y speed symbol in brackets.

A Few Tips About Speed Ratings…
Never mix tires with different speed ratings, as this may cause serious handling problems.

We don’t recommend downgrading the speed rating of your tires, as the vehicle manufacturer has done extensive testing to determine which tires match the various driving characteristics of the vehicle. However, if you are looking for better handling, there is generally no problem in moving up to a higher speed-rated tire.

Most importantly: Put safety first. The speeds shown are test speeds; they are not recommended speeds.

Temperature Rating:

A comparative grade based on the tire’s resistance to heat and its ability to dissipate heat, again as measured under controlled conditions. The grades, from highest to lowest, are designated A – B – C. An A-rated tire is the coolest running, while a C-rating meets the minimum federal performance standards. These temperature grades are set based on a tire that is properly inflated and not overloaded.

Traction Grade:

A comparative grade based on the tire’s ability to stop on wet pavement, again as measured under controlled conditions on wet asphalt and concrete surfaces. The grades, from highest to lowest, are designated AA – A – B – C. A tire that is graded AA should have better traction or stopping performance than a tire with a lower grade, based on the specific straight-ahead braking tests.

Treadwear Grade:

A comparative grade based on the actual wear of the tire’s tread when tested under specific controlled conditions. All tires are tested under the same conditions to allow for comparison between manufacturers and between different lines of tires from the same manufacturer. The system is fairly easy to understand. A tire with a treadwear grade of 400 should have a useful tread life approximately twice as long as a tire with a treadwear grade of 200. The higher the grade, the better the expected treadwear.

Looking for new tires with optimal traction? Or are long-lasting treads a bigger priority? There’s a simple way to compare tire specs!

The Uniform Tire Quality Grading (UTQG) system was developed by the Department of Transportation (DOT) to assist consumers in the purchase of their tires by providing a standard grading system used by all tire manufacturers. Tire manufacturers use the UTQG system to grade their tires in three important areas: treadwear, traction and temperature. The UTQG grade for each tire is shown on the paper label affixed to the tire and is also molded in the sidewall.

Treadwear Grade – A comparative grade based on the actual wear of the tire’s tread when tested under specific controlled conditions. All tires are tested under the same conditions to allow for comparison between manufacturers and between different lines of tires from the same manufacturer. The system is fairly easy to understand. A tire with a treadwear grade of 400 should have a useful tread life approximately twice as long as a tire with a treadwear grade of 200. The higher the grade, the better the expected treadwear.

Traction Grade – A comparative grade based on the tire’s ability to stop on wet pavement, again as measured under controlled conditions on wet asphalt and concrete surfaces. The grades, from highest to lowest, are designated AA ABC. A tire that is graded AA should have better traction or stopping performance than a tire with a lower grade, based on the specific straight-ahead braking tests.

Temperature Grade – A comparative grade based on the tire’s resistance to heat and its ability to dissipate heat, again as measured under controlled conditions. The grades, from highest to lowest, are designated ABC. An A-rated tire is the coolest running, while a C-rating meets the minimum federal performance standards. These temperature grades are set based on a tire that is properly inflated and not overloaded.

UTQG is a great way to compare tires from various manufacturers and between specific lines from the same manufacturer. Remember: The UTQG isn’t a safety rating and it doesn’t guarantee a tire’s mileage performance - but you can use the UTQG in conjunction with price, warranty, appearance and recommendations to make the right tire choice for your needs. If you have any questions about UTQG or various tire lines, the Big O Tires team is always ready to help!

Hauling groceries – or bricks? The Load Rating or Load Index indicates how much weight each tire can safely support.

Every tire’s load rating is stamped into its sidewall. Once you know the load rating, you can use the chart below to determine the amount of weight that one tire can support. Then just multiply the weight by four - or the number of wheels on your vehicle - to determine your vehicle’s maximum load-carrying capacity.

Load Rating Table

Sometimes the maximum load (for example, 1060 kg) will be stamped into the sidewall so that you don't have to decipher the load rating. Remember: never install tires with a lower load-carrying capacity than the tires that were installed on your vehicle by the manufacturer!

Load Range:

The load rating is a measure of the tire's strength — its ability to hold air pressure under load.

The load rating influences the sidewall strength of a vehicle tire. If a tire has a load rating that is too low, the handling of the vehicle could become unstable as the sidewall buckles under the vehicle's weight. Conversely, a much higher load rating than needed can dramatically harshen ride quality.

The recommended load rating for a vehicle's tires can be found in its owner's manual. It is also normally affixed to a sticker located on one of the vehicle's door jams. If you are replacing tires supplied with the vehicle from the manufacturer, the load rating written on the tires is an appropriate guide.

Sidewall:

There are other codes on some tires that provide you with additional information, some of which are specific to light truck tire applications. Some of the other codes that you might find on your tires include:

LT = Stands for light truck application. Example: LT235/85R16
C, D or E = Load range indication for light truck applications
REIN = Reinforced
OWL = Outlined White Letters
RWL = Raised White Letters
ORWL = Outlined Raised White Letters
B, BLK, BW, BSW = Blackwall or Black Sidewall
W, WW, WSE – Whitewall or White Sidewall
XNW = Extra Narrow White Width
XL = Extra Load Capacity

Section Width:

The linear distance between the outside sidewalls of an inflated tire without any load (exclusive of protruding side ribs and decorations).

Sidewall Aspect Ratio:

The ratio between tire height and width.

Important note on quoted prices:

Prices quoted do not include additional charges for sales taxes, mounting and balancing, valve stems, tire disposal fees, state recycling fees, tire protection plans and other charges.

How Are Tire Sizes Specified?
The first number describes width of the tire (section), the second number describes the aspect ratio (profile), and the third number the wheel diameter (rim size).
Alignment makes a big difference in how long tires last, how much gas you use, and steering and safety. When you buy new tires, we'll make sure they're properly aligned with a free alignment check!

What is TPMS?


TPMS is an electronic system that monitors the air pressure in your tires and alerts you when they are under- or over-inflated. Proper tire inflation not only boosts your safety, but also the life of the tire and its fuel economy.

TPMS

Some components of the TPMS sensor may need to be replaced due to wear and corrosion over time. Our TPMS rebuild kit includes all the necessary parts to service your TPMS sensor and keep this important safety feature functioning properly.
