GS Tire Wear Update/PS2 Owners your reviews
 

I know there have been a zillion threads on this but want the latest PS2 thoughts from those who have em and been running them :D

The Dealership I go to (that actually knows how to treat Corvettes and people and service them) will replace my front tires under warranty for the premature wear due to the alignment issue but I have to go with the runcraps. I really want to go with the PS2s.

Interested in comments from those who have switched to the PS2 s as there are very limited options .

TIA:cheers:

I have experience with the PS2 ZP's - in a word, Great.

You may well want to, if you have not already, read the threads herein about properly aligning your car for neutral tire wear with your new sneakers !! An alignment to GM specs will again prematurely wear the inside of your front tires.

Thanks Michael :thumbs: I am going to do a refresher on that. Tires won't be going on for a few days. BTW do you have pics of your car any place? It sounds HOT! :smash:

Have PS2 ZP's on my '08 Z51... What a great difference. None better IMHO... wearing well.:willy:

I own a 2010 grand Sport conv, i have 7500 miles & my front tires are worn down to thread wear indicators only the middle of the tire, is it possible that they could wear out so soon? the dealer said its not alignment problem, is there anybody else with that problem? thanks,

From n.j.

Joe, lots of us :( I am sending you a PM!

Joe...........join the club

I am also one of the unlucky ones with center tread gone but at only 5,700 miles. Please PM me if you have any information. :(

I started noticing mine around 5K too. I sent you a PM-hope it helps :thumbs:

Please PM me too. I have 8K miles on my 2010 GS. Front and rears are looking pretty bare.

We replaced our Z51 Supercar tries with PS2 runflats. We found them to be slightly softer, moderaterly quieter, more forgiving at the limits (more gradual breakaway), significantly better in rain. A better tire in every way i can detect.

Are the improvements worth the cost of turning down a new set of front tires? Only you can decide.

Would the dealer simply give you the new front tires, so you could haul them away? Buy four new PS2's and sell the Supercars?

Take their tires and immediately have all four replaced with the PS2's. You can then recoup ~$400 or so from them on here to help offset the cost of the Michelins.

I absolutely loathe the GY's & have replaced the tires within a month of ownership on every C6 (7) I've had.

:thumbs: Now there is an idea. I don't want the run craps. They tried sending it through giving me a credit towards the PS2s on the front but GM over rode that one :toetap:

:iagree::iagree::iagree::ack::ack: This Forum is full of great ideas :D

:lurk:

In for the info...
6,000 miles on my GS. Haven't dared look closely at them yet. Will today.

wow, tires for your '10 GS are expensive per tirerack. I would agree w. both Jim (Gearhead) and Russell (redzone), altho the PS2 ZPs on my '08 (non-GS) don't seem much better in rain than GY Supercar RFT. Still, the PS2 ZP is an excellent tire from what I can tell, even if it's less expensive because of sizes than it will be on your car.

And that idea of getting the free tires, taking them off and selling them to defray the cost of the full set of Michelins is a good one from any perspective.

Depending on wear pattern of your tires, it might be a good time to get a 4 wheel alignment at the same time for street use (I presume).

Good luck with it. :cheers:

Also take a look at the Bridgestone RE050A run flats. Much cheaper then the PS2 ZP but have a very good tread life. Quieter, and better wet and dry traction the the Goodyears. The Bridgestones seem to ride about the same as the OE Goodyears, to me. Lots of people on this forum have switched to the Bridgestones, with high reviews. Not saying the Bridgestones are any better then the PS2's(or any worse) but when you factor in the costs, the Bridgestones rate very high.

The dealer is working on it he is waiting for a response from the Rep,
I'll keep you posted, thanks

Does anyone know the difference between First Gen F1 Supercar & Second Gen.?

I switched to the Michelin ZP's on my Z06. I got just over 10,000 miles on the factory Goodyears, and they were really pathetic for the last few thousand miles. When I sold the car I had about 6,000 miles on the Michelins and they looked brand new. They also handled very well, a little quieter and a little better riding. I'm not sure if I ever drove them in the rain, so I can't speak to that.

I am on my third set of PS2's (2005 and then 2008 C6 Coupe). They are good for about 20k miles on my car which i think is great. Better ride, much quieter (and quiet all the way to worn out), much much better in the rain. The one downside is that the initial turn in with the PS2's is not as sharp as on the Goodyears. I have used both PS2 non runflat and the most recent set are ZP runflats - not much difference in initial turn in with either version of the PS2. I fixed it by upgrading my sway bars to JOC sways.

Went to my dealer to complain & got two new tires at no cost hope that helps

Don’t you have PS2s on the ZR1? So, you’re familiar with them, no?

I love the PS2 ZPs on my Z…much better than the GYs I had on my ’09 coupe; although I can’t make a direct comparison as my ’12 Z06 is a MUCH different car than the ’09 coupe, but I couldn’t imagine running GYs on the Z.

I say go for the PS2s, you can’t go wrong. :thumbs:

:rock: Good to hear :cheers:

LOL, good point:D They wear well, I know that :) The two cars are so different as you well know with your Coupe and Z:yesnod: Interesting to hear people's experiences and the difference with the two tires. I don't see anyone jumping up and down for the runcraps :lol:

I have 36,000 miles on my PS2's (non run flats). I suspect I'll get another 5,000 before they are shot. Yes, mainly highway miles.

When I had my 2007 I went to the PS2's and never looked back. Now with my 2011 GS I installed a set last week after chewing up the rear Goodyear's in 40 minutes at Road Atlanta.

However, one thing I forgot about was the protection lip Michelin puts on the tire. It makes it impossible for me to do my own alignments because our machine (I work for Lexus) doesn't have the special alignment heads needed to fit wheels with no lip to clamp on to. In fact, of the 5 shops I've worked at we never never had them. So I'll have to find a shop that can do it but I have a problem with ANYONE driving my cars let alone even touching them so it's a dilemma I have to deal with.

So if you make the move to PS2's know that all alignment shops won't be equipped for corvette wheels with lip protecting tires installed. Heck when I worked at the Chevy dealer we didn't have them there either. But I never had one come in with PS2's on it. None of this was an issue with the Goodyear's installed.

I actually made it to 14,000 miles on my 2011 GS. Now it's only been on the road 7 months. Just put Michelin Pilot Super Sports on yesterday. So far they are absolutely wonderful.

Any secrets on why the Goodyears are wearing out in the middle? I measured almost 2 degrees of negative camber on my front wheels (2011 Grand Sport) so I am going to the dealer next week to have them "square it up" so I don't get early wear on the inside edge. Anything I should know before I go?

Matt

Wearing out in the middle usually means your pressure is too high. There pretty much isn't any other reason. Too much toe in will eat these tires up in a heartbeat.

I read somewhere that GM has new specs for the GS.

Hi there !

Could you send me that PM too please ? Less than 6,000 miles on my 2010 GS and the middle of the fronts are worn . I can't believe I need new tires already . I always keep proper pressure and I don't track my car . I'm not happy . :toetap:

Thanks in advance ! ....Matt

Just joined the GY worn out tire club at 6000 miles
 

Unfortunately, I just joined the premature tire wear club at 6000 miles. I read the thread on this topic and noticed that some of you were sending out a PM to people with the problem. I am not even sure I know what that is, but if it helps talking with the dealer, could I please get you to send me a copy as well.

I have the same story, no racing, not track days, just putting around town with a couple of short road trips.Also any advice in approaching the dealer would be helpful. Did anyone take copies of the messages from this board with them?

Thank you very much!

We have a 12GS with 8000 miles on it. Was aligned at 1500 miles. Did not go to the Pfadt specs just partway out. Tires were still wearing on the inside front and rear so had them redone couple of weeks ago. Car feels great on the road but not enough miles to tell anything. Have had no problem with wear on center at 30 psi..
