The Kumho Ecsta PS31 tire is a high performance tire that enhances the look, and performance of any sport compact or luxury sporty touring car. The Kumho Ecsta tire features reinforced tread blocks for improved responsiveness, handling and braking. Wide lateral grooves maximize water displacement as well as wide four-channel circumferential grooves to improve hydroplaning resistance. The Kumho Ecsta PS31 tire also has a 3D dimple design in the tread sipes that minimizes movement in the tread. This reduces heat build for longer tread-life. The microgrooves are positioned on the diagonal to allow water to drain efficiently. The sidewall's racing-inspired checkered design communicates the tire's ultra-high performance capabilities. All these features and advanced technology means a great tire for any discerning performance enthusiast or value seeker.
This describes the sidewall appearance. Examples include Black Sidewall, White Sidewall, and 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.
|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)||1135||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)||51||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||10.5||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.|
|Tread Design||Not Available||
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||5.5-7.0||The approved wheel rim width range this tire will support.|
|Measured Rim Width||6.0||The recommended wheel width as recommended by the tire manufacturer to get the best wear us performance for this tire.|
|Section Width||7.9||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||23.4||The height of the tire when fully inflated.|
|Manufacturer Part Number||2168013||Manufacturer part number (sku)|
Good grip. Low noise and decent on wheel looks as well. Great tire for the price!
This will be my fourth set of tires on this vehicle. (2010 civic si). These tires exceed the factory michelans, the set of continental conti pro contacts, and the Yokohama es100s in every category in my opinion. I didn't have quite the budget this time around which is why I went with these tires. At a tire shop I used to work at, we sold the heck out of kumhos. I love these things and I have no worries when my wife and newborn take the car out. Wet handling is excellent. Dry handling is excellent. Braking... it's excellent as well. I won't know what these tires are like in the snow because I have a set of studded snow tires to throw in her car in the winter. But these tires are a perfect buy for someone who is either on a budget, or for someone who is just looking to buy some quality, well-performing tires with no price in mind. When they wear out, I'll be buying another set. 10 out of 10 from me. For the rest of you, go and get you a set!
Great tire and great price!!!!
Perfect commuter tires for my 2002 Honda Civic. They are quiet, comfortable, sticky, amazing wet performance, and so far have been showing signs of minimal wear(5,000mi). If you want a good set of tires for your car, but don't want to spend a fortune, get these ones!
