Yoko AD09 Question?

[spxxx]

Hi all!

Has anyone run this tire? Any comparisons to the current super 200tw tires?

Watched the Japanese video and they obviously don't have the superhero one lap performance of an A052 but would love to know if they're a V730 competitor.


Thanks!

I heard they’re faster than an A052 but Last longer which is interesting.
Quite good in the wet too. I’m gonna grab a pair for my next tires

They're not faster than A052's, they're more of a Michelin PS4S competitor leaning slightly closer to a Cup2 but definitely doesn't have the outright grip of an A052.

In some tire test the ran 0.6s faster than the A052. In most tests I’ve seen they’re neck and neck.
Definitely a fair bit faster than cup 2’s haha

It's a very impressive tire considering it's supposed to wear like an AD08R.

Wow I'm so happy to be proven wrong based on an early review from a buddy and one video from months ago. This sounds like a solid Nexen Sport-R / CRS competitor!!

Thanks y'all for bringing this to my attention, might be my new E46 backup car tires!

I ran 4 sets of AD08R before. They often heat cycle out well before they run out of tread. AD09 I feel would be similar.

A052 is a qualifying or autocross tire. You get 2-3 fast laps and then it goes to complete crap as it heats up.

Overall, I'm over the 200 TW street tires... none have the lap after lap consistency of a NT01, AR1 or SC3R tire. If you don't need a tire to do dual duty street/track or have class competition restrictions, just get the faster sub 200tw tire.

[Redd]

AD08R has been my go-to tire for many years now. As far as 200tw rubber goes they withstand the most heat, aren't as sensitive to pressure (I'm looking at you Federal), has good feel, and won't drive you insane with noise. While they're not the fastest they do have the best mileage and are usable right to the end of treadwear and won't try to kill you in the wet. That's important for me as a daily/weekend tire (I don't track much) cos it rains all the time here.

However AD08R is a very old design and probably one of the slowest 200tw tires today. I'm excited to try out the AD09 but my only concern is that I won't be able to swap left-right anymore to balance out camber wear as they went assym with the 09.

I have been running A052 for 3 sets now and they are definitely fast but also wear fast as well. They’re the cheater 200tw tire. I’ve switched to the new ad09 and I don’t notice a significant decrease in grip but they seem to wearing a lot more evenly and still grip pretty damn good. If you’re mainly street driving I would get the ad09 in a heart beat. I wouldn’t drive on a052 if you’re daily driving unless you plan on getting tires every 4-5k miles.

For reference I’m on 265/35/18 and 295/30/18

I also have a square set of 285/30/18 going on a square set of 18x10.5 wheels for the track. I’m not doing time attack or racing I’m just trying to get the most track time and minimize my consumables. So we’ll see how these do on the track.

Do you happen to have any lap time references or Aim data on both sets of tires? Would love to see the data on a heavier E9X

They are definitely not faster than A052. I've run them at Streets of Willow and Chuckwalla. They last FOREVER. Don't get very greasy and don't degrade after laps, physically. I can't believe how good my set looks after laps and driving to both tracks. I think it's a great practice/lapping/street mix tire, and visually, they are killer looking, if that matters at all.

I have a new set here I need to unload because I'm out of room @spxx happy to give you a deal on them if you'd like test.

How many secs off A052 and what's the total laptime of the track?

2 sec at Streets of Willow.
1:17.8 - A052
1:20.1 - AD09

Chuckwalla was a different story, but the aero imbalance is way more obvious at that track, and high front grip is really needed to get the car doing what you want. The grip of the A052 or RE71 is just way more impactful there than it is at somewhere like Streets. The weather at CVR was really, really bad though. Humid, dusty, insanely hot... and we had a flash flood midway through the day. So not a fair apples to apples comparison.

CVR:
1:59.1 - AD09
1:54.2 - A052

How does Re71rs compare to ad09/a052?

Like I said... I don't think they could be that bad, I just think my E92's worst qualities were overexposed with less tire under the car, and really, really poor conditions.

RE71RS is more dominant than the A052 in most cases, in my opinion. It definitely feels better on heavier cars like ours, thanks to stiffer sidewalls. Way more feedback, and less prone to greasing up after a few laps. They also physically wear a lot slower than A052.

A052's are incredible on their first laps, as are most 200tw hero tires, but they don't require much heat or anything to be in fighting shape. I think they favor lighter cars for sure. My experience on them in my 3100lb e92 vs driving a friends 2500lb e36 was wildly different. The A052's surprised me, though. I thought they were heat cycled out but continued to attend events on them just to see. I still ended up setting PB's at both CVR and Streets of Willow after 4+ days on them. Ultimately I corded the inside of my front left tire before the others were toast, but that's expected for lots of clockwise configurations.

If I had to choose one to buy and run exclusively, it'd be the RE71RS. In the name of science, however, I just fit a brand new size offering for the gen2 CRS. 295/30 on 18x11. I'll report back.

Where'd you get 295/30R18 CRS V2 from? Doesn't look like Phils or Tire Rack has them yet.

I'm a big fan of the 71RS...but I only got 13 HPDE sessions before seeing the start of cording on the left rear (???) of my ATS-V Sedan, and the same after 16 sessions on the fronts, despite rotating them side-to-side each day. On a heavier car I think they need to start absolutely no lower than 30psi and 30.5 is probably better cold.

There's not much you can do to fight the impact of heavy cars on rubber. Some handle it better than others. If you're towing, might be worth looking at proper slicks. Supercar 3R's come on the ZL1 which is definitely heavy... they have immense grip and work well, might be worth looking into.

CRS can be had in this size from my friends at R Compound, but they're out here in SoCal. Duane can definitely ship, though, so if you're interested, reach out and tell him I sent ya.

How much longevity do you expect out of the AD09’s? In terms of miles and/or track sessions

Can't give you an answer on that. I have over 1000 road miles and 2 track days on this set and they look VERY good. But there are people that go out and like to drive to the track and run 5 sessions for the entire 15-20 minutes... people with aero, people with full stock weight cars. Too many variables. I am none of those people. I like to set a few 10/10th laps, a couple cool downs, and lots of hanging out. Even still, these are going to last way longer than an A052 or RE71RS. Guaranteed. Just not going to match the grip. It's all tradeoffs when it comes to rubber.
