The Yokohama YK580 is part of the tire
test program at Consumer Reports. In our lab tests, performance all season tire
models like the YK580 are rated on multiple criteria, such as those listed below.
Dry braking is from 60 to 0 mph.
Wet braking is from 60 to 0 mph. Refer to the wet braking iText at the top of the Ratings chart for the specific speed used.
Handling includes how well the tires gripped in an avoidance maneuver involving a swerve into the left lane and back into the right lane; dry and wet cornering grip; and subjective steering feel.

Features & Specs - Yokohama YK580
Speed rating Speed rating. This letter denotes the maximum sustainable speed and is found directly after the load index. For S-speed-rated tires, it's 112 mph; for T, 118 mph. Speed ratings for other tires include Q, 99 mph; H, 130 mph; V, 149 mph; and Z, 150 mph plus. While such speeds may seem wildly impractical, tires with higher speed ratings tend to provide better handling at legal speed limits. Choose tires that have a speed rating at least as high as the one specified on your vehicle's placard.
Treadwear warranty Commonly used by tire manufacturers to market tires, the warranty describes the typical tread life of the tire. Consumers should view the warranty an indicator of tread life only. Actual mileage will vary with vehicle type, driving style, road, and weather conditions, just to name a few variables. Nearly all treadwear warranties are based on pro-rated amount based on the usable tread worn off the tire.
UTQG treadwear UTQGS, which stands for Uniform Tire Quality Grading System, is a federal government required grading system for passenger tires excluding winter tires. Key information includes Treadwear, Traction, and Temperature appearing on the sidewall of a tire. UTQG treadwear, an index developed by the government, compares a tire's tread life with that of a reference tire graded at 100. A tire with a grade of 300 is predicted to last three times as long as one graded at 100. Treadwear grades are just one indicator of tread life, but actual tire life will vary due to a number of factors including road conditions, driving habits, vehicle, and maintenance.
UTQG traction UTQGS, which stands for Uniform Tire Quality Grading System, is a federal government required grading system for passenger tires excluding winter tires. Key information includes Treadwear, Traction, and Temperature appearing on the sidewall of a tire. UTQG traction indicates the tire's ability to stop on a wet surface with Government grades of AA, A, B, C, from best to worst.
UTQG temperature UTQGS, which stands for Uniform Tire Quality Grading System, is a federal government required grading system for passenger tires excluding winter tires. Key information includes Treadwear, Traction, and Temperature appearing on the sidewall of a tire. UTQG temperature indicates the tire's ability to resist heat build-up under test conditions with Government grades of A, B, C, from best to worst.
I wanted to give you some feedback on the YK580 Yokohama tires that I have had on my 2007 Subaru Tribeca. I purchased the YK580 Yokohama's for my Subaru Tribeca in September 2013. Not until recently did I get a good feel for them on ice and snow. I'm very disappointed in the handling of this tire in ice and snow. Very poor traction. I know they are not a snow tire, but I did expect better traction control on turns and slow-downs with a reputable AWD. I own another Subaru and have Hercules Tour 4.0 All season tires with over 15K miles on them, and they are so much better.

How long have you owned it:
A month or less
Yes, I would recommend this to a friend.
Good Fuel Saver
Great tire performs as advertised. Bought 10 months ago approx 10K miles. Fuel mileage average since install on Ford Escape Hybrid is 35.3 MPG with 50/50 mix driving. I would recommend this as an energy saving tire. Great low rolling resistance.
