Rated 4 out of 5 by from Big Foot A/T 2015 Ram 3500 crew cab. I pull Rv's from manufacturers to dealerships across the country. About half of my mileage is unloaded. I have installed Centramatics (wheel balancers) to help maintain tires balance. I currently have 86,000 miles on this set of tires and I am happy with the all around performance of these tires. I have had to make sure the tires were rotated often because they have a tendency to cup on the steers. Maintaining proper tire pressure is a must for long life. Tire balance and good shocks are also very important. Let's face it, your vehicles suspension must be well maintained to get great miles out of a good tire.

Rated 4 out of 5 by from Great tire, decent price, good performance I decided to give the Big O Big Foot AT a try on my 08 Tundra Crewmax Limited 4x4 after shopping around due to the great warranty on these tires and the price, the manager with a little negotiating even gave me a discount. After having these tires for almost a month, Iv put over 3k miles, a trip from KY to FL and back and all over the farm I am extremely satisfied with the tires, great traction in grass and mud, does have a little road noise but not bad at all for a AT, great control on hwy and in rain. I will most definitely buy again. If your looking for a great tire with great warranty at a good price, give them a try.

Rated 5 out of 5 by from Great tires Needed new tires to replace the "car tires" that have been on my Ford Ranger. Got these "truck tires" and the shop put one size larger than what I was planning on. Gave them to me for the same price. They ride so nice, quiet, and amazing grip. I'm not spinning my wheels as I turn the corner at stop lights and I can hear the creaks and rattles of my truck so I can pinpoint where they are coming from now. My truck now drives the speed limit (the speedometer matches the radar signs now) where before it was off by about 5 mph. And they look great! The truck looks like a truck now not a car with a truck bed. amazing what a good set of tires will do for your truck. Even a little one.

Rated 5 out of 5 by from Pleased So Far Put these tires on a 2010 F150 FX4 replacing the OEM Wrangler SR-A's. So far they have about 500 miles on interstate/highway at speeds up to 85 mph. Additionally abou 60 miles of good dirt road at 60 mph. Really impressed with the smooth ride and quietness on the high speed runs. Stability on the dirt road in SE Colorado was excellent. I bought the tires for a bit more confidence on forest roads to access trailheads. But I didn't want to give up much on-road performance as 95% of my miles are on pavement. So far these tires meet my expectation.

Rated 4 out of 5 by from Currently on my third set... I work off road within the railroad and pipeline right-of-ways. I've had other tires throughout the last 10+ years - but nothing holds up to what these tires have to deal with on a daily basis.. On regular highways they're good as well. Good in rain, medium to heavy snow and pretty dependable on ice as well. I also bought these before Christmas 2016 for my 1996 Jeep Grand Cherokee Limited. They handled super in a major winter storm in Northern Utah.

Rated 5 out of 5 by from Beautiful Tread The Big Foot A/T has a very handsome tread that is not so aggressive that the highway seems like a cobblestone road but just aggressive enough to climb steep logger loads to haul out my fire wood in the good old '83 3/4 ton 2WD Chevrolet pick-em-up truck! These tires are far better than the Good Year Wranglers that I replaced because of cracked sidewalls and a bumpy ride (oh and a flat). The recent rains on an oily road proved to be a real test of the new tire stability - and these tires displace the water and hold the road as well as any I have ever known.

Rated 5 out of 5 by from Back Country Backbone I drove multiple trips up and down a gnarly 4-wheel track for elk hunts in September and was impressed with new tire performance - through muddy bogs, over miles of sharp rocks, through heavy storms, traction was terrific. Drove well with heavy duty chains when needed, and smoothly back on the highway after shaking out the mud balls. Replaced earlier Big Foot A/Ts with new set because the old ones were great; these are even better.

Rated 4 out of 5 by from Look Great I have these tires on a Jeep liberty and I have been overall happy with them. The off road performance is excellent and dry summer and wet road is great as well. I live in Colorado and we get just about every kind of weather during winter months and I would say these tires perform poorly when the temperatures get really cold. They do great in fresh fluffy or deep snow but any hard pack or icy areas they feel like ice skates. I beleive this has to do with the rubber compound getting really hard at extreme cold temperatures. Highly reccomend for an all around tire but err on the side of caution if you plan to use these as a dedicated winter tire.

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.

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.
