Even with the extended warranty that I bought through the dealer I used an indy that was much more cost effective. When I used to take the car to the dealer and had a problem with a tire I ended up having to go to a tire shop to have the problem solved anyway.

Friggin' A, but they just don't lose pressure like air filled tires do!

Finally bit the bullet and bought a set of the new Michelin Pilot Super Sports, had them installed last Tuesday.

FWIW, Discount Tire ran a special a couple of months ago in conjunction with a Michelin rebate.

I use Nitrogen fill, mainly for its stability over 4-6 months of winter hibernation.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Yes -- it's used in large commercial/military aircraft tires as it's hard to check & fill them, but they also go through amazing temperature changes under extreme loads.

Suggestion · Original poster
I bought them through Costco as the Price installed (about $1,170) was basically the same as several of the local shops and Tirerack with shipping and local install, but Costco included a road hazard warranty and nitrogen fill which would have been another $150-$200 with the other sources ( they also include free rotation but that doesn't do much good on a 996 with staggered sizes).

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.

Finally bit the bullet and bought a set of the new Michelin Pilot Super Sports, had them installed last Tuesday. I bought them through Costco as the Price installed (about $1,170) was basically the same as several of the local shops and Tirerack with shipping and local install, but Costco included a road hazard warranty and nitrogen fill which would have been another $150-$200 with the other sources ( they also include free rotation but that doesn't do much good on a 996 with staggered sizes). I have to go back for another balancing as I have a slight shimmy between 75 and 90.
I only have about 150 miles so far but my initial impression are very good. They are much quieter than the PS2's I took off last fall, but the rears of those were almost bald, and quieter than the Dunlop Snows that came off (again pretty much worn out). Had one rain so far and they seem great in the wet.
They were not available in an N rating, but then neither are the Hankooks, Bridgestones or Sumitomo's that I also considered. The new Super Sports are significantly less than a set of PS2's and are supposed to corner better and last longer.
Looking forward to having the new tires for the summer and will post my impressions as time goes on.
I didn't think Costco carried the correct sizes for a 996 - did you special order through your local COSTCO?
Nothing comes up on the COSTCO Website for me.
I made exactly the same switch a few weeks ago. I sucked it up and paid a little extra to support a local shop, but the service I get there is worth the extra money. So far I have the same conclusions. I'll be running these at the track as well so we'll see how they hold up.
S.
Glad you're enjoying them. I wish they had been an option for me with a wide-body car. I just put on a new set of PS2s, and they are awesome. I love them. I've heard the Super Sports are even better...
Doug:
I will be interested to hear how much you like them. I just had a full set installed about a week ago and haven't had much driving time on them yet.....but that will change shortly.
This is why I'll NEVER have tires installed at Costco on my Porsches. How does this "save" you any money when you have to return to get the job done correctly?
I'll be at Loeber Thursday for a set of PS2's going on the Boxster. This will be the last set of PS2's I purchase. Next set in about 2 years will most likely be the new Super Sports. The PS2's have been excellent to me.
I just wish the Super Sports came in the right sizes (295/30/18 and 235/40/18) for my Turbo.
FWIW, Discount Tire ran a special a couple of months ago in conjunction with a Michelin rebate. Out the door was right at $900.00.
I have about 500 - 600 miles on them and so far they are great. So much so that I will not consider low tier tires for this car in the future.
- What sizes did you get?
- I assume you trusted that their tire changing machine would not harm the wheels.
- Please continue to post how your experience with them goes. These seem to be a viable replacement for the PS2's. Not sure why they're not N rated.
Thanks.
I have about 6000 miles and 5 track days on mine...and am very impressed with the ride quality, performance and durability...they are showing only minimal wear....highly recommend them.
My local Costco does not stock any Super Sports, but special ordered them. I ordered them on a Monday and they had them the next day. With my 2000 the OEM sizes are 225/40-18 on the front and 265/35-18 on the rear and the Super Sports are available in those sizes. If they were available in the 285/30-18 I might have gone with those, but at this time they only come in 285/35-18
As for buying from Costco versus the dealer this was a no brainer for me. If the dealer would have been willing to get the Super Sports (no N rating so they may not have been willing to do so) they probably would have been $400+ more expensive based on my experience, and that would not have included road hazard or nitrogen. Loeber is particularly uncompetitive, every time I call them for a price on parts they are typically 10%-20% higher than the the "list price" in PET. If one wants to pay them a premium for old technology tires that is not a problem with me but seems rather silly. I was running PS2's before the new Super Sports, but why buy the old technology tire for more money?
My car has not been to the dealer since it came off the factory warranty. Even with the extended warranty that I bought through the dealer I used an indy that was much more cost effective. When I used to take the car to the dealer and had a problem with a tire I ended up having to go to a tire shop to have the problem solved anyway. I will stop by Costco for lunch later this week and have them check the balance. Might be a simple re balance or a problem with the tire or it might be the wheel, I will have to see. But my experiencing with P Zeros and PS2's is that they often need some additional balancing.
I just did a quick Google search on nitrogen in tires and the primary benefits seem to be that it does not migrate through rubber as easily and if pure has less moisture in it compared to just air. I saw some tire shops charging as much as $7.50 per tire for nitrogen. Costco uses only nitrogen. The tech there laughed at the high charges for nitrogen noting that the air we breath is 78% nitrogen.
Buy your tires from places like Tire Rack. Then drop them off at the dealership (they don't fit inside the Porsche unless it's an SUV). Loeber charges about $45 per wheel plus the cost of OEM weights.
I've never had to return to the dealership for "additional rebalancing".
Nitrogen for car tires is sort of a racket.
Yes -- it's used in large commercial/military aircraft tires as it's hard to check & fill them, but they also go through amazing temperature changes under extreme loads. Nitrogen requires less filling and keeps a more stable pressure -- important if you need to retract them into a confined space. I don't know of any typical, private aircraft that use nitrogen in their tires. Have never seen it offered at typical, small airports.
The benefits for car tires are more theoretical than practical where checking them regularly due to road debris is important.
Buy it for its conversational value--('hey, guys, guess what I got...')--not because of any real benefits. Won't hurt anything.
Nitrogen doesn't leak out. I had a rare Fiat that went out for the occasional run 3-5 times a year with 25 yr old tires that has had nitrogen in for at least 15yrs and tire pressures never changed. I was talked into it in about 1991/2... I also thought about putting Argon in, but didn't for some reason. I was very impressed as it stayed exactly the same for so long. The wheels were magnesium and I was more concerned about moisture and oxygen corroding the insides at the time.
I also agree, that DRY air SHOULD be every bit as good as a nitrogen fill. But in my experience, it hasn't. 3 different cars, different tires (not the 996, tho), all tires and nitrogen at Costco. Friggin' A, but they just don't lose pressure like air filled tires do! The stuff works, and I'll be damned if I can explain it logically. Same experience with pressure in these cars as David above.
I have the Super Sports and have done 2 DE's so far and the tire wear is not bad. I really like the tires. Quiet yet they scream when they are having fun. The grip is great in corners and my entry speeds have gained a ton. Next step up for me is track tires.
1way2rock: With 40 MM more rubber at the rear you gain dry grip - some like myself think too much rear grip. The wider rear tires can push the dry handling balance more towards understeer than the stock tire sizes. Some people like that setup, and it certainly looks very racy, but I prefer the more lively handing of the narrower rear tires.
I had a set of Supersports on my 01 996 last season. I did like the tire but not the wear. My suspicion is that the sidewalls are not as stiff so that ride comfort could be improved. I do a lot of DE events each year and these were the 9th set of tires on the car since I purchased it in 01. I found them to be quite sensitive to pressure and would advise that you to keep the pressure up so that roll over is minimized rather than reduce for better grip. I did not...my hot temps were 34/36.
6 DE days at Calabogie Motorsports Park finished off the fronts (corded on outside edges) and wore out the rears with the same wear pattern. Plenty of tread mid-tire and inside edges. Alignment had as much camber as possible without modifications.
I am back to the Yokohama AD-08. Sidewalls are very stiff and they are not directional so I can swap side to side to minimize wear.
I would have no hesitation in recommending the SuperSports for street and light DE use with careful attention to pressure.
By the way, the tread wear warranty is void if you track the car.
I agree! To worsen the issue & show how fantastic the Super Sports are I have 5year old 225/40 PS2 & new 265/35 Super Sports on the rear. It is very difficult to get the car to turn in on autocross courses. I also noticed how flexible the SS sidewalls are by gripping by hand & they do seem to ride better than PS2's.
Thanks a lot!
I was looking for this information from long ago. I am going to order 285/35R18 and 235/40R18 for track use.
I guess it is difficult to adjust the air pressure because load index of MPSS is different from MPS2. If you have recommendation pressure, please let me know.
What he said. It supports Rennlist, too.
I can ship to one of our installers or to your shop of choice, too.
Pleas call me if I can help in the future.
I have Michelin Pilot Super Sports on my 928 and on my Ferrari - good tires.
For my 996, I decided to mount BFGoodrich g-Force T/A KDW tires
Front: 8 x 18 et57 225 40 ZR18
Rear: 10.5 x 18 et60 285 30 ZR18
These tires are good in dry and wet, and have great stick. Nice agressive tread.
