Yokohama Advan A052 review

I'm on my way to my 4th set of Cup 2's(always on stock size) and i can't think of a better tire for the money. Period. I use them all year and everywhere, and it rains a lot in my area.

PS: AD08R's always get great reviews but i can't see what all the fuzz is about, had those on my 205 and i wasn't impressed. At all. Pretty decent on dry tarmac, and that's about it.

PS2: If you can afford them and want the very best, take a look at the Pzero Trofeo R. Available in 205 or 225 but well worth it. Better than the Cup 2 all around, but at the expense of a shorter life i suspect(i have these on another car but they're still "new").

PS3: yeah, i'm kind of a tire geek

How did you not like the AD08 R? Are you sure you’re getting them up to the proper temperature?

[Surok]

AD08R like 30 PSI hot too

Correct, that's the issue for now... But the regular PS4 is a very capable tire on dry, and excellent on the wet.

If you think about the current range and how good the PS4 is in smaller sizes, and having the Cup 2 for those of us who want the very best dry handling, having 3 sport/performance (or 4 if you add the remaining PSS sizes) tires makes little sense.

IIRC at least by Michelin data it's capabilities were reported as being on PSS level, with slight loss at just one of dry track tests, but slightly better everywhere else, especially wet. So you get almost same as PSS, but at even wider sizing choice and better wear (also important thing, even on track, as can reduce spendings on wearables). If PSS are still considered as competitive choice, why not non-S MPS4? Even more so for dual-use tire choice. MPS4S most probably will be better, but until they are available at R17 size, i'm still considering getting non S-es for next season in spring.

I agree. PS4 is a good substitute for the PSS in small sizes for most users. You loose a bit of dry track performance but if you really care about that, you'll go PSC2.

If you think PSS have grip, you havent driven on a performance 200TW tire or even "cheater" tires (RE71R and friends). PSS is an exellent tire for the rain and daily drive, nothing more, it cannot handle the heat at all and the sidewalls are made of cardboard.

PSS's dry grip is really good, even now that it's a bit outdated. And they last long even if you use them on track.

Obviously you can't compare to more track-oriented tires, but you have to keep in mind it is a road tire. And a really good one.

I don't know why, temperature/pressure wasn't the issue. Perhaps i just had really big expectations after all the good words about them. Dry handling was good but they lasted less than 10,000km on a car weighting less than 900kg, which is quite absurd considering i am a smooth driver. Wet handling is not very good because of how hard the sidewalls are, which also had a big impact on ride comfort.

Iceman: if AD08R lasted only 10Kkm, now imagine how long cheater tires like RE71R might last . If one of pros of Essex BBK kits was hailed cheaper & longer lasting wearables (much thicker pads of common shapes) that let BBK to pay-off soon, then imho many underestimate tire wear importance for self-financed track day enthusiasts.

Left is the RE71R and right is the A052.

Ive been running AD08Rs for the last couple years.

Ive done around 8km road and 6 or so trackdays.

They have around 3.5-4mm tread left and the last trackday it was wet and they were terrible. i couldnt get any heat and they just slid about. A friend on PS4s had alot more grip. id say 20seconds in a lap.

Is it possible my AD08R have be heat cycled out? They are about 3 year old (been on my car 2 years) and have been used in two winter and recently in sub zero. One day it was -6C and snowing.

I love them i nthe dry and these A052 caught my eye as they have an A rating for wet grip.

I have the same issue like you and I would like to have a bit better wet grip. It is also my 3rd year with the AD08R tires.

It is true about the wet grip rating of the A052, but on the other side the Yokohama global site(*) provides the rain symbol only on the AD08R's. So, I am not sure who is correct and who is wrong. Someone that maintains the Yokohama site or the European testing agency? In general the A052 tires are quite expensive and still don't have many reviews. I was tempted to test them, but it is a lot of wasted money if their wet grip is not better.

small bump on this old thread.

I have purchased a set of A052 for my car, for track purpose only. So far, i've tested them only on the wet.
They're very good on the wet. Best tyre i've purchased being honest under those conditions. I was way faster than a lotus A380 cup with PS cup2 at this time.

What have your previous track tires been?

[venturaII]

My Japanese is lousy, to say the least. Still, entertaining to watch...and a direct comparison of RE-71 and A052 on the 86 platform, though in larger 245/255 size, from what I could see. He was trying as hard as he could to keep up with that FD RX7..lol. The results at the end clearly show the A052 as a direct competitor to the RE-71R on track, though I don't know what the test conditions were...cold tire? Warmed up and then a single hero lap? What are they like after 20+ minutes? I see mention of 3 and 6 lap measurements, but I don't know what the ratings were.

The A052 is superior to the RE71R for raw grip and heat capacity, but cost significantly more.

I have tested a lot of different compounds:

Federal 595 RSR
Toyo R888R
Yokohama AD08R
Michelin Pilot Sport Cup 2

On the dry, i'm running michelin slicks S8C

I have not tested the A052 on the dry yet, but knowing Yokohama, they should be quite good.

If the extra grip and heat tolerance mean the A052 ends up being a more durable track tire than the RE-71, then a good portion of that cost increase is removed. Now, if I could only get my current set of tires to wear out faster..lol.

Simple. Instead of HPDE try drifting
