Rated 5 out of 5 by from Best mud tire on the market I put a set of KM2s on my 08 Tundra a few years after I bought it and they were expensive but I believe they are the best quality mud tire on the market. They are a little noisy and they don’t do great on pavement but they are outstanding when you get in the mud and the way they make your truck look is just worth it IMO. After the KM2s eventually wore down after about 50k miles I went ahead and got some KM3s and they look even better than the 2s and I feel like they are a little quieter on the highway. Not to mention the 2 sets and over 100k miles over all kinds of misquite thorns and road debris, I’ve never had a leak in any of my BFGs so far. I can’t say the same about the Michelins on my Camry or the Goodyears on my Tacoma. And don’t settle for the cheaper Taiwan made Nittos either.

Rated 5 out of 5 by from Over 5 years and 40k+ miles!!!! Bought a set of the KM3s when they first came out. I had the first Land Rover Discovery 2 on KM3s in the USA. 5 1/2 years and 40k miles of wheeling from the swamps of Florida and everywhere else on the East Coast, they are ready to be replaced. No dry rotting, plenty of tread left, they have just worn a little funny (to be expected in a mud tire) and have gotten quite noisy. What am I replacing then with??? KM3s of course!!!! Best tire I've ever owned!!!

Rated 5 out of 5 by from Best on the market The best M/T tire on the market! I have run quite a few other manufacturers M/T tire and so far this is the best out of all of them! These are replacing Nitto trail grappler and for people saying that B.F.G tires are cut small, once I had these mounted and under weight of my Jeep they measured the same. On the road the KM3 handles better then the competition and on the trail they do a amazing job! Even on wet roads they hold traction way more then other M/T tires. I am definitely going to keep running B.F.G tires from now on!

Rated 5 out of 5 by from Great tire, but pretty expensive now. I've ran the 39x13.5r17 KM3s for 2+ years and over 40k miles on my Jeep Gladiator. I've put these tires through all kinds of terrains and weather conditions from dirt, sand, rock crawling, mud, rain, hail, rock crawling in thunder storms and they haven't let me down. I keep rotate them every 3k to 5k miles and they have worn evenly. The side walls have been holding up great and the side bitters have provided plenty of traction when needed. The light weight of the tires is also a plus. My only gripe is these tires have gotten fairly expensive since I purchased them in 2021. The price has increased roughly by about $250 per tire. They are almosted priced near the cost of some 42s. Well known competitors 40s don't even cost as much as these 39s. With that being said it opens the door to try some of the top competitor's tires for about $200 less per tire. These 39s compared to most 40s make the 39s look like 37s because of the actual size.

Rated 4 out of 5 by from Feels Quite a Bit Different from the KM2s I used to have K2s before I got my 285X70R17 KM3s. Here are some differenced I have observed: The KM's are noticeable wider than the KM2s. I did not measure the width of my KM2s, but I had to cut the stops on the tailgate for the spare tire on my Jeep JK by about 3/8" for the tire to fit onto the spare tire holder. So I would say the KM3s I have are about 3/4" wider on the sidewall than the same size KM2s I replaced. This is not a complaint - I just thought I would share my observation. The KM3s feel "squishy" compared to the KM2s. I am running them at the same 37 psi as the KM2s. The "squishy" feeling is very noticeable on turns and the Jeep rolls much more than it used to. The steering response also seems to be diminished. When I make a sharp turn, there is a very brief, but noticeable delay in the vehicle responding, and when it does, it feels like it is grabs. The KM3s have a different noise than the KM2s. The KM3s have a higher pitched hum than the KM2s. This higher pitched hum is mildly annoying. I have read that the tires get noisier over time. Hopefully, the noise will not increase too much. I realize these tires are more intended for off-road use as opposed to highway or city driving. I have not tried them on the trail yet.

Rated 3 out of 5 by from Worst on winter driving with snow and wear Good in mud and loose soil. Terrible in snow and always get irregular wear well before the tread is used up, even with frequent rotation and alignments. These wear my second set and I will not be purchasing a third set and going with a competitive tire company.

Rated 3 out of 5 by from Great tires, undersized, over priced I’ve tried just about every off-road, AT, MT tire made over the years. I keep coming back to BFG for the quality tire that they are. Currently running the KM3’s on my Jeep Gladiator. These tires work great on road and are exceptional Offroad. The two main complaints I have, which is pretty standard on all BFG truck tires. Undersized for what size they advertise them to be. And I’m not talking about just a little bit. BFG’s are some of the worst about under sizing. ALOT. Once you get to the really tall tires, the prices are outrageous compared to their competitors. I’m in need for a larger size now and the BFG price is outrageous on 39’s (which are actually 37.75” tall supposedly) sorry BFG’s looks like I’m gonna have to go to your competitor after all these years

Rated 5 out of 5 by from Siped they are great for Winter and Summer in Alaska. I have been running these 37x12.5r17 on my 2 door wrangler custom siped in the center 8” of tread as both a daily driver and trail riding both winter and summer here in interior Alaska. They wear faster than the K02’s, but aired down to 25psi they work exceptionally well on hardpack snow and ice, through 2 feet of snow in winter, and medium mud loads in summer. And they don’t clog up in the deeper stuff (snow or mud) like the K02’s do.

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. Prices may vary from one store to another or from one date to another. Tires listed may not be in stock at the identified store. Prices listed were received from individual stores and have not been verified by Big O Tires. Please call the Big O Store of your choice for up-to-date information and details on pricing, additional charges and product availability.

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.
