Describes the sidewall appearance. Examples: BSW= Black Side Wall, WSW = White Side Wall OWL = Outlined White Letters.
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 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.
|Load Range/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)||2535||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)||44||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||14.0||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.|
Nondirectional - most common, same tread pattern on inside & outside of the tire. Can be rotated to all four corners of vehicle. Asymmetrical - tread pattern is different on the inside to the outside of the tire, and must be mounted properly. Can be rotated to all four corners of the vehicle. Directional tires - roll in only one direction, must be mounted properly. Once mounted they must remain on the same side of the vehicle, and only be rotated front to rear.
|Rim Width Range||6.5-8.5||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||10.2||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||32.1||The height of the tire when fully inflated.|
|Manufacturer Part Number||90000046777||Manufacturer part number (sku)|

Price was great, shipping was very fast! Have purchased from tires-easy.com twice and will buy from them again!
Far out competes the bridgestone deuller in wear and tread design...........
A good tire for the money
I've run Cooper several times before. As a vehicle service technician, I am more aware of the pros and cons of certain tires. The only reason I didn't give 5 stars was because 1 of my tires has excess road force. Even after match mounting, the road force exceeds limits. I can feel a very slight vibration from this, but only at highway speeds.
Bought these for my 2012 Jeep Patriot. They came extremely fast and there were no imperfections observed. They sold for less than a tire chain I was looking at locally. Had them installed at a shop and love the ride. A little bit louder than my last set which were GoodYear Wranglers but I can definitely feel more grip and fuel economy difference is minimal. I would definitely buy more from this website in the future.
Love my tires
Great tires. Would buy again with out a dobt. Tires easy are great to work with. Fast shipping and friendly staff.
Great tires no road noise great traction
Like these tires
An all around good tire
Enjoying the ride!
Installed on my 2003 4x DBL Cab Tacoma. Great traction, comfort and low noise. Recommend!
Got these tires for my wife's 08' gmc canyon and they have been great in the snow and rain so far! highly recommend these
short term comments
Fitted to stock 2010 Forester. Went from stock 215/65/16 to 215/70/16. Was glad to see this make available in the size I wanted, not many other AT tires in that size. Fitted well, no rubbing in wheel arches at any point so far. Immaterial effect on fuel consumption, no noticeable increase in road noise or impact to vehicles acceleration ability. Only about 5k on them so far so can't comment on wear or winter performance yet. So far I'm pretty happy with them, only gripe is they pick up a lot of small stones in the tread, but maybe that's par for the course.

Your tires are Great ! When I Need New Coopers Your 1ST To Call.
Thank For The Tires.
these tires perform great in a wet road or rain condition,
these are a all around great tire I am happy with them, they run quiet, they perform great in the rain and on wet surfaces, my old tires would spin on take off but these stick to the road on take off on wet roads, plus you do not lose traction when braking on wet roads, all around great tire, easy purchase quick shipping
Great tires so far
Driven with it for over 2 months now. Mostly summer season and rain. Its definitely an improvement from my stock tires. I havent noticed any road noise and it does a great job at absorbing road bumps from the city streets. Also noticed a difference when going over speed bumps, i can barely feel the bumps.
Fast chipping, fear price.
These tires are great
Great tires for the price
Great tires for a great price. Last forever if you rotate them every 5000 to 5500 miles
Quiet and smooth
We put these on our Jeep Grand Cherokee they look great! Have not been off road yet but they are great in heavy rain
