Take it from me. I was in your exact position just a month ago.

I had PSS on my 20" LMs and was pretty impressed. They felt very similar to my 19" PS2s, however cornering wasn't overly impressive.

Fast forward to now....I put in a S/C and wanted to lose some unsprung weight -- I switched to 19" HRE Monoblocks and needed to choose between AD08 or PSS for my tire.

Due to the stiffer sidewall, more square stance, and better dry grip, I went with the AD08s and I havn't looked back.

People say the AD08's are noisy - As someone who would generally notice a noise difference (if it was a big difference), I literally hear no difference, whether driving with windows up or down. Now I'm sure there MUST be a difference because everyone says the AD08's are louder.....but to be honest, they sound so similar that I wouldn't even mention noise when comparing them. They're certainly not loud to the point where they are overbearing or annoying. Then again I do have an Eisenmann Race exhaust so that could be overtaking the noise of the tires.

The stiffer sidewall was noticed immediately, as the car felt incredibly balanced and my turn-ins were razor sharp. Add to that the fact that the ride wasn't harsher due to the stiffer sidewall, and I was surprisingly impressed! I went with big tires (295) in the rear and front (265), and I couldn't be happier.

If you're not tracking the car, I wouldn't worry as much about rain performance OR tread life, as the only places these things will be more pronounced is if you use them on the track.

So to me, it came down to weight. The PSS weigh considerably less than the AD08 (2-4lb less), and to me that is the biggest advantage. While you may be pressed to actually notice the weight difference while driving, just the knowledge of having the least amount of unsprung weight as possible is confidence-inspiring.


So, if you're a weight-nut and want to be able to brag about having the lowest possible unsprung weight, go with the PSS. If you are really worried about hydroplaning as your cruising down the highway, go with the PSS.

If you want maximum dry grip and a meaty, monstrous looking tire, go with the AD08. Either way you can't go wrong!

if you arent tracking the car and dont really care about having the ultimate grip, pss is probably a better dd tire for cruising.

i also recommend avoiding a 5mm spacer. they arent big enoguh to have a lip over the hub and almost always cause signficiant vibration and issues. 10mm or larger or none.

FYI, there is a new version of the AD08 on the horizon with a better compound. Google it. I think it's called the AD08R.

It's an r-comp racing tire. Not what I would necessarily want for a street tire, though.

While the gap between what is an "r compound" and "street tire" is narrower than ever, the new AD08R will be considered a street tire and the direct replacement for the AD08.

Its competitors are the Bridgestone RE-11A, Dunlop Direzza ZII, BFG Rival, Hankook RS3, and Kumho XS (soon Kumho will have an Ecsta V720 to replace the XS).

It will likely have a 200 treadwear rating when it comes stateside so that it qualifies for the new SCCA street tire class rules.

That's great news, I think. I drew my conclusions from the promo video that is all in racing context. A 200 treadwear r-comp sounds interesting. That's harder than the AD08, which is 180 iirc.

Its all relative. It will most likely be a softer, grippier tire but given an artifically high treasdwear rating to be able to be used in several racing platforms. Basically a cheater tire.

Basically for these sticky new tires, tread wear isn't a very good rating. With the SCCA doing the 200 treadwear street tire limit, most tire companies who made the 160-180 treadwear tires will just say they are 200 tread wear. The AD08r is not a r-comp!! The R is just a designator like on the RE-01R.

I'm sure these will be available about 5 minutes after I get my AD08s installed.

I'll have to look at the AD08R closer on the next tire change. I need an excellent wet performance tire living in the PNW. The PSS is currently tops for me. Technology advances are a good thing...luv it!

With AD08 running wider than PSS, would a 295 AD08 = 305 PSS?

255/35R19 AD08 Tread Width 9.9"
255/35R19 PSS Tread Width 9.2"

275/35R19 AD08 Tread Width 10.6"
275/35R19 PSS Tread Width 10.2"

295/30R19 AD08 Tread Width 11.5"
295/30R19 PSS Tread Width 11.5"

It's in the 255-275/35 sizes where the AD08 has a wider tread width.

Exactly. Treadwear numbers are some of the least reliable numbers in the industry. Because consumers expect that low treadwear = high grip, manufacturers seem to set them artificially low for performance tires. Then if the rules change, they just raise the numbers and say that they 'discovered' that the wear was better than they had estimated.

Assuming grip level from treadwear number is somewhat like assuming horsepower from fuel economy numbers. One car gets 18mpg, the other gets 20mpg. Which has more horsepower?

I use 5mm spacers and have yet to have a problem (with HRE and Volk wheels). There is enough hub protrusion to still maintain hub-centric install. I do however think that it can be an issue with some wheels that have more of a taper at the hub. I measured my hub protrusion and it is 11mm therefore I don't run 10mm spacers due to possible issues with hub compatibility - See below.

Quote from Turner Motorsports: "A note about 10mm spacers: Any 10mm spacer is considered a custom fitment. The stock hubcentric lip on BMWs can stick out by as much as 11mm. This leaves a gap between the spacer and the hub which seriously compromises safety. We recommend using a larger spacer (12mm and larger do not have this issue) or check that the lip sticks out less than 10mm."

So for me its either 5mm or 12.5mm Turner Motorsports spacers.

This is my dilemma right now. I'm looking for tires for my track wheels, that will see 4-5 track days, and 4-5 autocross events this year, and I'm trying to decide which tires to get before I go to COTA next month.
The wheels I bought have used AD08 on them, but I notice chunk marks out of both rear tires, and at an autocross tow weeks ago they had much less grip (granted rears were at wear bar) than my stock PS2s. I've used Direzza and RS3's for autocross in the past and likes both, but since I'll also be doing a few track days, in addition to autox, I'm not sure if I should get PSS, Direzza, Rivals, or RS3. With the chunking on the current AD08's I've pretty much rules them out.

Thoughts for a stock car doing 4 track days and 4-5 autox events in 2013 (and hoping to not replace tires to complete this number of events).

Sounds like you want a tire that will last till the wear bars. RS3's are awesome out of the box (especially for track events since they handle heat well) but tend to fall off a bit before they reach the wear bars.

For an auto-x focus, some of the new tires you should take a look at are the BFG Rival, Dunlop ZII (The ZI's were pretty consistent), and the Bridgestone RE11A's. PSS is more of a 9/10ths tire with better ride and wear with street focused driving with some track thrown in. 10/10ths driving requires something that is more focused (ie Extreme Performance category).

If you are not serious about your results and are willing to compromise for a better overall street experience, get PSS. If you want the best performance and limit dry handling characteristics, try the ones listed above.

Note, wear depends on the use case since the tires wear differently in different scenarios. The PSS will wear better on the street but the Extreme Performance tires tend to hold up better on the track (ie no chunking) due to the tread pattern design and compound.

How did the chunking come about on the AD08's? If you don't know, i wouldn't rule them out b/c you bought them that way. They can handle heat like Hankooks can, much more so than all the 'Max' perf tires (aka PSS). I've shredded/chunked PS2's in less than 25 autox runs/7k miles. My Yoko's are going to last well more than twice both those numbers, they just require more warm up time now which is probably what you are experiencing if they are at their wear bars. Mine have slowly gone from fast on the first run to being fast on the third run.

If you push your tires, I'm fairly certain the PSS' won't meet your expectations for autox or track duty.

+1, Yokos are a track tire moreso than an autox tire just like the Hankook RS3. The new AD08R looks tasty for track use!

I too got chunking of the ad08 and switched to nt01s which delaminate instead. The ad08s are now used as a wet tire for me.

Would u not consider the HANKOOK RS3?

They're very highly rated and compared to AD08 and cheaper as well.

These are for my track wheels, so very few street miles, except getting to and from some of the events. I have my stock wheels for day to day driving. I know PS2's aren't in the same category, but I wanted to try out the car before my wheels came in so I did one event on the PS2s. The plan isn't to do that permanently.

The AD08's were used at a few DE's on a fairly stock E92 M3, at the same tracks that I might visit.
TH AD08's did get faster, but over 6 autocross runs, I was still slower than drivers I was faster than the month before on my PS2s, and even on the 6th run I felt the car slipping in the back, and not gripping in the front as much, and the front AD08's were in much better shape than the rears.

The RS3's are on my list.

My list is Direzza (newest version), BFG Rivals, PSS (problem coming off the list), RS3.

I may just stick with the RS3's.
