Yokohama YK580
UTQG: 580 A, A (All Sizes)

Introducing the latest evolution in high performance all season tires, The Yokohama YK580. A truly next generation tire with
a first of its kind High Performance rubber compound technology that achieves low rolling resistance and long tread life. The
new asymmetrical tread design delivers enhanced wet weather grip, confident cornering, powerful stopping power, and an
extremely quiet ride. The YK580 has a large size line up and several new fitments for passenger and CUV vehicles. Yokohama
made an intentional focus on tread life of the YK580 and offers a warranty on all sizes and speed ratings. To achieve this, it
was put through rigorous testing on the harshest surfaces and the strictest guidelines and was engineered to achieve a best
in class rating in multiple performance categories. Its technology, construction, and design are the outcome of years of
engineering and research. The YK580 promises to exceed all expectations while at the same time contributing to a cleaner
environment.
 

 
TECHNOLOGY
Engineered for Extraordinary Longevity

  • Our most durable, High-Performance Compound achieves low rolling resistance while delivering long treadlife
  • Our Optimized Contact Patch promotes long, even wear by distributing stress equally across the entire tread surface
  • We optimized the Groove Ratio by almost 9% to increase tread area and volume for more stability and longer treadlife.
Developed for Year-Round Traction

  • For improved handling in the rain, our Sweeping Tapered Rain Channels accelerate water away from the tread area.
  • Our Cross Traction Sipes create biting edges for assured handling in light snow and wet conditions.
  • Our 3D Adaptive Sipes give the YK580 consistent traction for the duration of the tire's life.
Built for Quiet, Confident Handling

  • When cornering forces are pushed to the limit, our Unibloc Shoulder enhances the stiffness of the tire
  • The YK580's Large Notched Blocks provide grip support under the most intense braking and cornering pressure
  • Our Tread Block Bridges give the tread extra support and reduce tread noise throughout the life of the tire
Economical and Environmental

  • Because the YK580 has such low rolling resistance, it improves fuel economy. And thanks to an all new compound and
    optimized tread profile, it's guaranteed to last thoudands of miles which is good for both the wallet and the environment.

I put these tires on my 2008 Fit Sport about 6 months ago. Original were Dunlop SP 31 A/S. 195/55R15. It may be coincidental, but I am having poor fuel economy issues right now and am trying to find out rolling resistance info to see if these, being a high performance tire according to Yokohama, may be contributing to the problem. My gas mileage has dropped considerably and i can't figure out why. The ads refer to the YK580's low rolling resistance, but no further data. I'm pulling my hair out and am tempted to drop hundreds of dollars to go back to the OEM Dunlops to see if the MPG gets any better. Drastic, I know, but I'm at my wit's end trying to figure out why I barely get 20 MPG.
Any thoughts on this subject? Thanks.

Timflan, thanks for the info. I'm really curious as to if you found out if it was the tires causing the problems or something else. Anyways, hope you figured it out by now, and wouldn't mind posting if you're still around. Thanks.

Sorry for the delay timflan. I'm not sure how we missed this thread.

The YK580 is considered an ultra high performance all-season so the rolling resistance won't be as good as the OEM SP31 tires. The YK580 though, does utilize Yokohama's latest compound technology for reduced rolling resistance so you shouldn't have had a considerable drop in MPG. Has your MPG improved since your post?

Default MPG still terrible

Just filled up today again, 5/4/2012. Only 19ish mpg, 20 if I cheat the numbers. Still very poor for this car. I've talked to Honda Corp., many dealer service departments and even the motorheads at work, with still no answers. The car runs great, no engine lights, proper oil/filter at regular change intervals, new air filter, etc.. I'm at my wit's end with this car. Very frustrating to say the least. I've only had Honda Corp. say to bring it in to a dealer for a "fuel economy test"! What a crock there, calculate miles driven by gallons used. I'm no dummy car-wise and know how to calculate MPG, that's how I know how crappy it is. Dealer's offer no real help.
My next drastic move is going to be to lay out a bunch of money to install what was OEM, the Dunlops. Some will call me stupid but I have to know if the Yokohama tires are doing this. It's my last hope . If the problem remains, I am selling the car. BTW, I'll have some fairly low mileage YK580's for sale here in about a week here in Texas! Anyone interested???

There are so many factors that can contribute to change in MPG that it's tough for us to help diagnose if it is indeed the tires causing the loss. What were you averaging before you replaced the stock tires?

Default I just had to know!

Well, today I went ahead and bit the bullet and replaced the YK580's with OEM Dunlop SP31 A/S, 19555R15's at just over 30,000 miles on the Fit. I put 3154 miles on the YK's. I had to travel 50 miles to Austin to find them in stock at a Discount Tire and filled up on the way back. I only got to check a 40 mile trip so far, but am encouraged by a 24 mpg on that 40 miles. I know that's not an accurate average on only 40 miles, but time will tell.
A couple years ago I seem to remember mpg in the low 30's, but when it dropped to under 20, it got very frustrating. The car is in fine shape mechanically with recommended maintenance up to date. No check engine light; filters, oil, tire pressures all good. Runs great with plenty of power.
I'll post back after a couple tanks. This mpg stuff is pretty basic. I was an aircraft mechanic for 23 years and am always tinkering with something that burns gas. I am an operator in a power plant now. What I'm trying to get at I suppose is that I'm mechanically inclined enough to know that something is fishy. Hopefully the Fit was just overly sensitive to a different tire? Stay tuned sports fans!! Thanks for the reply. And life goes on.....

After seeing the Yokohama YK580 review by Bob Faieta on YouTube.com, I was extremely pleased to find out I would be going to Miami, Florida to push the YK580 to it's limits at Homestead Miami Speedway. Here's what Bob had to say about the new Yokohama YK580.
YOKAHAMA YK580 REVIEW - YouTube
I arrived in Miami Monday, April 9th late in the afternoon and after a nice dinner at Tarpon Bend in Corral Gables, I went to bed early in anticipation of the following day's action. With the three hour time zone difference I would be getting up at 3 AM Arizona time so a good night's rest was in order.

After a quick continental breakfast at our hotel we arrived at Homestead Miami Speedway around 8:30 AM. After passing through security we pulled into the center of the track where a couple of Mitsubishi Evolutions were sitting with YK580 tires installed. Seeing these vehicles immediately got my adrenaline flowing. I would come to find out later that the Evolution would be one of five different vehicles we would be testing the YK580 on.



From the bus the Yokohama Representatives led us through the paddock to the drivers meeting room where we would get a run down on the day's events and what makes the YK580, the YK580.





The first thing we were told from the Yokohama Representative in charge of product development was that the YK580 is the new benchmark for future Yokohama products and is one of the best tires Yokohama has ever produced. Needless to say, this was quite a statement which made me even more enthusiastic about testing the YK580 and pushing it to the limits.

But what makes the YK580 one of the best tires ever produced by Yokohama? It's predecessor, the YK520, was a good model. So what did Yokohama do to make the new YK580 even better? Compounding and enhancing the tread design were part of it, but it was the testing, testing, and more testing that led to these changes and elevates this tire to the top. The YK580 was put through it's paces two times the regular amount a tire is usually tested to ensure it lives up to the expectations set by Yokohama and Discount Tire. The YK580 was tested under aggressive driving conditions, on severe test courses, for a significant number of miles and through every test Yokohama learned from it and made appropriate changes. Through this rigorous testing utilizing multiple vehicles, Yokohama can confidently say that the YK580 will not only reach it's prescribed tread life but will provide predictable handling and superior ride quality while doing so.

After our briefing we were split into four groups and sent out to test the YK580. We were going to test the tire on multiple courses and my group was headed for the 0-60-0 braking course first. Here we tested the YK580's braking ability on the Evolution and Nissan 350Z.



I do not have any stopping distances to report as the vehicles were not equipped with data loggers. What I can tell you is that the YK580 gripped extremely well off the line (much to my surprise) with the peddle straight to the floor and had very limited pull when I slammed on the brakes. Granted the vehicles we were driving were Brembo equipped, but none the less I was very pleased with the grip the YK580 offered from a dig.





Next up, the dry autoX course. Dry autoX courses are my favorite for testing a tires ability to corner and respond to my steering inputs. The YK580 didn't let me down. We challenged this course in a brand new Mustang (v6) and Scion TC. The RWD Mustang weighs more than the FWD TC which allowed us to test the YK580 on two vehicles with completely different dynamics.



I noticed entering the first turn how quickly the front tires responded to my input which allowed me to drive the course with less input throughout in both vehicles. Taking corners the YK580 held tight and gave me ample notice when pushed to the limit. This was surprising as most all-season performance tires I've tested in the past gave me very little to no notice before the limit was reached. I contribute the YK580's responsiveness and predictability to the uniblock shoulder and large notched blocks which adds stiffness, grip, and support to the tire under hard cornering pressure.





From the dry autoX course we headed over to the wet handling course. Yokohama set up a small course with a long wet sweeper that turned into a wet skid pad (to simulate ice). We tackled this course again in a Mustang (v6) and Scion TC. I was only able to test the tires on the Mustang as I got held up taking photos.



I entered the sweeper with a good amount of speed and the YK580 held the line perfectly and with limited roll. Upon hitting the skid pad I could certainly tell a difference in traction but I was easily able to maintain my line by letting off the throttle slightly. The sweeping rain channels and lateral grooves do an excellent job evacuating water from underneath the tire allowing the YK580's tread compound to really stick. Coming off the skid pad in the Mustang was a blast as I was able to smash the throttle and maintain a short but controlled drift.





After the wet handling course we made our way over to the road noise test. Yokohama set up a 12 mile trek on public roads outside of the speedway where we could see how comfortable and quiet the YK580 rides.



In the Nissan Maxima there was little to no road noise on the surrounding roads even with the equipped lower profile 245/45-18 tires. It was a nice change of pace from all the fast action we were experiencing earlier. The cool AC (the humidity was pretty gross that morning) and smooth, quiet ride almost put me to sleep while I was sitting passenger. That was short lived though as we turned down a rocky and dusty dirt road. The ride wasn't so quiet any more, clearly, but we did manage to have some fun dusting out the other test car behind us.



After a catered lunch of wraps and subs we headed to our final test of the day, the high speed road course! We utilized the 2.2 mile infield road course for this test where speeds near 90 MPH were reached at times.



After a crash course with performance driving tips from a professional Skip Barber Instructor, I made my way to the only open vehicle, the Scion TC. The 350Z, Mustang, and Evolution were taken already. I was ok with that though as I was very excited to drive this course. Falling into line behind a driving instructor in a Nissan 370Z, we hit the course. The YK580 was predictable under braking and consistent through the corners. Like we observed earlier on the dry autoX course, not much steering input was needed and the grip off the corner exits was precise and smooth. The optimized contact patch talked backed if pushed too hard. After running 3 laps around the road course I was amazed that an all-season performance tire was able to perform so well on this fast course.


After completing all five tests I was convinced that the YK580 will satisfy the needs of today's performance vehicles and their drivers who need an all-season performance tire without compromise. The wet traction, steering stability, dry grip, and responsiveness makes the YK580 an excellent model to consider for your next purchase.

Here's what the YK580 installed on one of the Scions looked like after a hard days beating.
