I saw this post in C7 section

Made me wonder if for 2012 you can get the new lightweight wheel with the old tires? At least for the drive home and the break in period brake burnishing etc. IMO it seems excessively expensive to use 2/3 of the life span of a $4000 set of tires before you ever approach the redline or enjoy doing a over steer through a high speed corner.



Nice to have traction when you need it but what about taking a florida vacation and having to add 4 grand to the trip just to cover tire expense. ....... I would not even want to be able to afford that unless I was already making some HUGE donations to charity.

If the tire life is a concern to you then it is not for you. You better off getting a second set of wheels/tires.

We'll see what price them come at when they are avaiable..I'm finding it hard to believe they will be close to 1K per tire.

Neither Michelin or TireRack have them available yet in 335/25ZR20... You can probably guestimate from the other available sizes. I saw one (brand new) yesterday in 335/25/ZR20 - it looked half worn out with a treadwear rating of " 80 " .

I think they could easily be $800 or $900 each. Take a look at the info below from Tire Rack's website. You can see that there are several sizes of the MPSC+ N-Spec tires that are approaching $700.

I think the one for the ZR1 will be even more limited in sizes - only ZR1 to start with. Also, it's a ZP (Zero Pressure - Michelin's term for "runflat"). So, I bet it will certainly be their most expensive streetable tire!!!



So.....we'll have to wait and see what they will cost when they become available - but it ain't gonna be cheap!!!!!

If tire wear is going to cost me $ 1.33 per mile, from my point of view you are absolutely correct.

I used to change $150 DR's every 700 and thought that was excessive

Now as far as the new wheels being available with the old tires..... from the original release I did not get that impression. Does anyone know for sure? If so I can afford their wear rate

Luweegy

Discount Direct has them for 660.00 per tire.

BEZ06

Huh????

What size do they have for 660.00??? Is that for each front tire? What does the rear size cost?

I looked all over their website and didn't see any MPSC ZP tires at all.

Can you direct us to more info, maybe a link to their site showing that pricing and what sizes are available?

I didn't think you could get these tires anywhere yet.

TIA,

I could get almost 10K miles out of sport cups on my Porsche with quite a bit of track use. On the street they should last longer with a good alignment. I bought a set at the track, after cording the old ones, and drove 250 miles home to discover the nibs still on the tread!

dvandentop

i would rather get their real race slicks at that price and it will ourperform them on the track @550 per rear tire.

Shurshot

That is encouraging..... I am hoping that the engineer who claimed a 3000 mile longevity for the new cups was embellishing a little bit

I ran the stickiest P tires I could get on a pro tour 96 SS and got 7500 -8000 from them .......... and that was some pretty hard miles on a 4000 pound plus car.

.

I agree but then there needs to be a truck and trailer....... then before long you might as well just build a dedicated track car

What one person gets in one state really can't be used as a benchmark, unfortunately. Just data. Road materials differ from state to state. Some roads aren't as rough on tires as others are. Ambient and road temperatures matter. And whether your state has yearly "safety" inspections will also matter.

I can almost guarantee that here in VA, those Cup tires wouldn't last a year. The pavement material we use here is sandpaper-like. I could roll into the gas station for my annual inspection after the first year and they'd laugh me out of there because of the lack of tread.

Other states may be different.

I have the factory Sports Cups on my ACR and after 2000 street miles they aren't showing too much noticable wear. I'm betting about 8-10K out of them with no tracking. But I plan on tracking it this summer some so they'll be shot much quicker.

CrystalRedMetal ZR-1

If these wear slow enough to warrant a good 8-10k miles I'll buy some for my ZR1.

PDCjonny

I'll tell you one thing tho...they are stickier than hell great for the track but if you're planning a lot of street driving you better put something on the wheel wells and rockers because they pick up every grain of sand and throw it against the car.

When I got my car within 100 miles I had paint chipped off behind the wheels. Had everything clearbra'd after that.
The tires look like you dipped them in bread crumbs when they are warmed up, they are that sticky.

FNBADAZ06

Anyone not clear bra'd before they run these tires are going to be in for a rude awakening....they truly are that sticky and will fling every piece of road debri at your body panels

Michael ZR1

Had them on my 911 cords showing on rear by 6000 should have replaced at 3000 they were out of spec

Michael ZR1

And yes it had a clear bra and you. Oils here them throw everything

I used MPSCs on my Z06 and loved them as a tire I could use to drive to and from the track. I had them on a second set of stock Z06 rims and I did not use the MPSCs as daily driver tires, but I know that many do. I usually track at Autobahn in Joliet, IL. Autobahn has a 2.2 and 3.5 mile configuration, with a lot of tight corners (22 corners on the longer track).

The tires wore significantly more on the outer edge, even cording my fronts at the outer edge while there was plenty of inner tread left. This was with the stock alignment. I then went to -1.5 all around and had somewhat better wear but I know they could use even more camber. I bought some used MPSCs for the fronts that were used on a Porsche in the rear. The Porsche wear was much more even, wearing the inner more than the outer edges but more even across than my tires, but I have no idea what camber was used on the tires and I know it is apples to oranges with 911 vs vette weight, etc. After 2 track days at Autobahn in the ZR1 the outer edges of the 2 left PS2ZPs are already showing significant wear compared to the rights.

I think a good solution may be the Pfadt camber kit if it is usable on the ZR1 (the website says Z06 with no mention of ZR1). That way you could dial in all the aggressive camber you would need for the track and then dial it back out for improving street tire life, whether it's for MPSCs or PS2ZPs. $350 for the kit plus install is way cheaper than the cost of the Michelins. Does anyone have experience with this kit in the ZR1?

Also, for JVP and others that run R comps in the ZR1, how are the tires holding up re: wear and are you still running stock alignment?

When I got my ZR1 I swore I'd track it in stock form but the damn bug is already hitting me!

jvp

I ran all last summer with the stock alignment. First session of this year was run with a slightly more aggressive alignment from a camber and toe perspective, but nothing too nasty. Tire wear is pretty even and tame, mainly because I rotate them and run them backwards every other day. As long as there's no water on the track, the direction of the tread doesn't matter.
