I am running the ZIII's very happy with performance and price

FWIW, I use 295/30 r and 235/40 f on my '02 996 (GT3 size wheels and offsets) with no rubbing.

Suggestion
Going back to the original conversation, when mine wear out I�ll probably keep going with the PS2s since it�s likely I�ll have to replace the rear before the front anyway.

I'd used to just set my pressures cold the night before and drive all session like that- when I tried that with the Star Specs, I was all over the damned place on later runs.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Need to get new stock tires for the Carrera 225/40x18F, 265/35x18R.
I had Michelin PS2's which I was happy with, but for a daily driver I am trying to find something more affordable and came across this
recent summer tire test in Car & Driver.
Doing a forum search I see a lot of recommendations for the Sumitomo HTRZIII, which is what I was leaning towards. The test doesn't include that tire, but gives the Dunlop Direzza Sport Z1 Star Spec top ratings.
Any thoughts or advise appreciated TIA.
I read that test an I guess I took the results a different way. The test seemed to validate the idea that the more expensive, big brand tires are indeed better all around tires than the less expensive brands.
I would have liked to see the Sumitomo's and General's in the test, but I doubt they would have beaten the PS2's or the Dunlops.
agreed there is NO WAY the sumi's are going to BEAT the PS2 (the benchmark) BUT for daily driving - "Stock" tires, they are a bargin and have been given the thumbs up by many RL users....
a few of us have had them out at track setting including DE's and autocross and give them a favorable rating...again, mostly for day to day driving and by no means the best tire... but maybe the best tire for the price......and a rating of 93% compared to 100% for the PS2's on tirerack, are most commuters going to be able to get that exrta 7% overall rating out of the tire anyhow.... (at double the price)
That said, if money is no object, get the PS2's - plenty of data supporting their performance
The Star Specs are amazing for the money. They crush the PS2s @ auto-x. The only downside is that they are somewhat noisy.
I have them on my S2000 and have been extremely pleased. More grip than my heat cycled out Victoracer R comps.
I've had PS2s on the C2S and they were fine - just not $496 per rear tire fine. Never tried the Sumi IIIs but was unimpressed by the Sumi HTRZ IIs (had them on our LeMons Festiva)
If you want quiet and comfy tires - don't get the Dunlops. If you want serious grip - they are excellent tires.
I'm running the Dunlaps this year. They are great in cold weather and oddly very sticky in the rain. So far in the "Summer Dry" nothing has competed as well as the Yoko Neovas however, the Dunlaps aren't too far behind.
It is shocking that in the 5+ years that the PS2 has been out that no other manufacturer has managed to knock them off the podium.
My C4S came with a brand new set of PS2s and they really are wonderful. I went from PS2s to Dunlop Star Specs on the 993, and while the Dunlops did pure handling better than the Michelins, they were just a bit worse everywhere else. If they start making the Dunlops in 295-30-18, it'll be a tough call, though.
My rear non N-PS2's in 265x18 last about 25-27k. Not a fluke since I am on my 3rd set, and at 99600 miles. So, at $300, which I paid last time, they last 2x as long as any N-rated tire I had before (p-zero). Therefore, a bargain compared to all the ones tested in the C & D article.
Thanks for all the responses, I think I shall try the Sumi's. I could always try the Dunlops next year, it's not as if it's a 30,000 mile commitment with these cars.
On stock 18in wheels would there be any advantage in upping the sizes while I'm at it?
I've got about 4K miles on my Sumis now. I'm pleased with them.
I wish they had been included in the test - it would have been nice to see where they stack up...
Where did you get those prices from? I just checked Tire Rack and they're $342 for the new PS2 model. Still expensive but not quite $500.
Going back to the original conversation, when mine wear out I�ll probably keep going with the PS2s since it�s likely I�ll have to replace the rear before the front anyway. So I�ll be only purchasing two tires compared to switching to another brand will force me to purchase four new tires and there goes any cost savings.
Just something else to consider�
What I want to know is why they used the PS2 as the comparison tire? This was only the 4th place tire in their 2005 tire test.
http://www.caranddriver.com/reviews/...mparison_tests
Conspicuously absent were the new Yokohama Advan Neova AD08 (or the old AD07) and Goodyear Eagle F1, which both bested the PS2 in 2005.

I thought I'd chime in since I have personally run in the past two years:
RE505A N0
PS2N1
R888
V710
V700
Star Specs
HTRZ II
RT615 (Falken)
I've got Star Specs on my 04 Boxster S, and I must say- they are absolutely amazing autocross tires. I've had excellent experience with these tires in the wet and dry. I did notice a little more road noise with them, but it's not like they're howling or anything, they're just a little louder than my old tires.
Haven't tried them in the rain yet but they are really fast out of the box for auto-x. No need for a 2nd driver to keep them warm!
The R888s howl. Not really a big deal since they are R comps but I am still blown away by the grip of the Star Specs.
Good point, except:
The Yoko is nowhere near as comfy or quiet as the PS2. Put the AD07/08 against the Star Spec--that's a good matchup.
Goodyear for some reason refuses to make the F1 in any size that might fit the back of a Porsche. The F1 and PS2 are great competitors otherwise. Just not for us.
I did notice the Star Specs are a lot more sensitive to temperature and pressure than my old tires. I'd used to just set my pressures cold the night before and drive all session like that- when I tried that with the Star Specs, I was all over the damned place on later runs. Now, I bleed air between runs like they're R-Comps, and performance stays consistently good.
And speaking of which, where are the Bridgestone RE-01R/RE11Rs?
Looking at the price matrix, I think they were culling "cheap" tires specifically; if the $192 PS2s are excluded, the Dunlops, at $137 apiece, were the most expensive tires on the test. The neovas and RE11Rs are all about $50 more than the Dunlops, aren't they? I would still like to see them directly compared, but I think that's why C&D chose to do Ling-Lings as oppose to something people might actually WANT to see compared to the PS2.
Agreed. Cheaper and lighter. I just used my OEM wheels for the R888 since I ordered some 19" 3 piece wheels for the street.
Starting from scratch - I would have gone 18"
Wow, I just read the article.. I think they could have used a better group of tires to match up with the Dunlaps. I mean, ling longs?? Come on! I do agree on the assessments of the Dunlaps but this test would hardly convince me to purchase them due to the sad group of tires they match them up against.
I ordered my Sumis today. $708 w/road hazzard to my door for 4 tires (04 40th edition w/18s). Replacing Pzeros. I will keep my two fronts for back ups if needed. I just couldn't justify $780 for 2 Pzeros for a daily driver. I hope they will be delivered tomorrow or Friday.
Thanks, just want to confirm before I pull the trigger on these tomorrow.
Mine is 00 Carrera, stock tires are 225/40x18F, 265/35x18R. Could you confirm that putting those 285/30's on the back will:
1. Fit my stock factory wheels
2. Not cause any rubbing
3. Not cause alignment issues
BTW are stock 4-wheel alignment settings ok on a daily driven road car? or are ther any recommended tweeks required there.
Sorry for all the questions but I know a lot about 951's but absolutely nothing about 996's.
Mike,
Assuming you have 10" wide rear wheels. the 285/30 will NOT cause any rubbing or alignment issues. Also, Porsche stock alignment settings are fine for a daily driver.
285/30 18's will fit your stock 10" rears fine and should not cause any rubbing or alignment issues with stock offsets. If you want to reduce understeer a titch you could also move to 235/40 fronts.
FWIW, I use 295/30 r and 235/40 f on my '02 996 (GT3 size wheels and offsets) with no rubbing.
Finally, if you want a little more aggressive alignment for the street I suggest you try the x74 alignment settings.
Tires just dropped off at the house. Boy was that fast. Order placed 7:30am on 7/15/09 and all 4 delivered at 1:50 pm on 7/16/09.
I think I will take a personal day tomorrow to have them installed.
Why didn't you have them delivered to the shop you're going to install them at? How are you getting them there?
That's what I've done with Tire Rack in the past - huge convenience!!!
I am not sure which shop I am going to use. I am going to get some string and tie them to the roof.
Not. My daughter, who is playing couch potatoe this summer, will follow me in her durango.
If she's too tired just check out Washington DC Porsche's picture above!!!
Holy crap, you must have gotten some looks when you pulled up to the tire shop. Talk about efficient use of space!

Tirerack's latest review came out, and showed what we all wanted to see: RE-11 vs Star Spec vs Ecsta XS vs AD-08. Looks like an awesome new crop of tires any way you cut it! Of course, once again, TireRack goes and does something stupid like ranking extreme performance summer tires by including noise and ride comfort with the performance tests. WHY, TIRERACK, WHY?? I think they gave the Kuhmos an unfair overall rating; the Kuhmos look to be just phenomenal dry tires, even if they do suffer in the wet. I mean, 1.01gs on the skidpad? :shok: Looks like the AD08 carry a similar 14F temperature warning to the AD07s, which is a consideration for many of us, too.
That 14f was a worry for me at first until I realized how often temps in my area rarely get that low while I'm driving. However the AD07's in the winter allows you to slide thru turns which can be fun. I couldn't get the Star Specs to break without considerable effort. I didn't know much about the RE's I love Bridgestone tires, I might have purchased them instead of the star specs had this test been available in January.
I'd prefer a tire of Chinese or Korean manufacture. And I must have blue smoke when drifting. Given these requirements, the PS2 is clearly a lame pretender.
