I have a 2017 Grand Sport with Michelin Pilot Super Sport ZP tires on it. It seems to spin them up rather easy and I was wondering a couple of things about the Michelin Pilot Super Sport Cup 2 tires. First do they grip a whole lot more on straight acceleration. Secondly I have heard that they wear much faster then the Michelin Pilot Super Sport ZP. Also will this tire make the car ride any different or make it handle any differently while just normally cruising along at highway speeds. I would appreciate any comments on this topic since I have a friend who would buy my take off tires that only have 2,000 miles on them right now. Thanks for any light that you could shed on this topic.

Sport Cup 2s wear out twice as fast as Super Sports. I'm getting 20K on Super Sports vs. 10K on Sport Cups. This is where I draw the line. That's a lot of money.

I'm glad they went with Michelins. Tread wear is 300 on the '18 Stingray, as opposed to 220 on my '13 and 200 on the '06 Goodyears (Z51). They didn't last 15k miles. You may get a bit better performance (grip), but unless you're going to track it, lot of money for half the life.

If you think about getting cup 2s,get RE71r instead and save a lot of money for almost identical results.

Maybe a nice tire but they don't have the rear tire size. The max size is 40 mm narrower than the GS rear tire.

Rich,

Any tire you buy will spin up like you describe if you use the throttle as an on/off switch. The LT1 engine has as much torque off idle as the C6Z LS7 engine which is a lot. Nowhere near as much as the LT4 in the C7 but still a lot. You can't go around making sudden changes in throttle settings without shocking the tires and breaking grip. You can still go wide open but you have to do it in a proper manner so the tires don't get shocked by a sudden torque increase. Try rolling your foot on and off the throttle VS dropping the hammer. You will be rewarded with tires that grip when you take off and you can still progress to wide open. What is better, sitting still spinning the tires or slightly hazing the tires as the car shoots down the road at max acceleration? This isn't like driving a rubber band powered Toyota.

ah true, forgot about that.

Anyways, a stock GS should not easily spin the 335 section rear SS ZP tires. That's pretty wide for the power. If your plan is to cruise on the highway and a little more grip, you're SOL. The cup 2s will actually grip less than the SS on the street until you warm them up good.

There really is no better street tire than the MPSS for Grand Sport size. I have 600+ hp/tq on 285 rear section tires and I grip fine in 1st and 2nd (actually only lose grip after 5500 rpm or so when the fan starts blowing hard). You should have no problem with 460 and wider tires by driving properly.

The Cup tires don't come alive until they are warmed up significantly. You won't launch any better with cold or lukewarm Cup tires. You'll also hydroplane more easily if there is standing water on the roads.

When the Cup tires are warm though, it's a fun experience. They're soft enough to lay rubber even without wheel spin. So an earnest departure from a light will still leave faint tire tracks. Very soft rubber. This was further proven when my Cup tires with Z06 wheels developed grooves across the tire just from sitting on the bars of a wall tire shelf.

Hey Guys!
I want to sincerely thank everyone of you who responded to my question. You guys did clear this up for me and I will stick to my Michelin Super Sport ZP tires. I guess that like some of you said I was looking for the unobtainable best of two worlds. I don't and will not take my car to the track because I like it to much for that. I will try the technique of rolling on the throttle versus hammering it down. I have never done a whole shot with any of my Corvettes but I plan on shortly maybe doing one with this one, I have only had it since April of 2017. What I like to do is just normally accelerate up to around 15 MPH and then stomping to WOT and then it always spins them right up especially if I don't have a passenger in the car.

Hey once again thanks to all of you, you are all a great bunch of guys.

THANKS from Rich

The Michelin Super Sport ZP tires are the best choice; however, you'll be lucky to get more than 15K miles out of them since they only have 6/32" of tread depth brand new compared to most tires which will have 10/32" I have had loss of control issues with the SS ZP tires in very heavy downpours having never experienced such a problem in my other Vets I've owned since 1990. The tires are VERY wide and with their minimal tread, especially on the outside half of the tire, it didn't surprise me. The rear tires on my C5 are narrower than the fronts on the '17 GS. The SS ZP also need to be just a little warm before they stop skipping/jumping in high radius turns, like backing out of one's driveway. For what it is worth, I won't be replacing them with the OEM tire. For summer use only, they are outstanding.

I went with Michelin Pilot Super Sports (non run flat). I'm using 285/35ZR-18 up front and 345/30ZR-19 in the rear. Ordered from the Tire Rack and had them the next day!

Two years ago I hit a concrete pot hole getting off the freeway and blew the front right tire. It was the non zp type and had been purchased off of Tire Rack. They covered the tire and replacement cost no problem. Here is a picture showing the hole with a large screw driver thru the hole to show it. Purchased a replacement and still have them on the car today. Over 30k miles and they still show lots of tread.

TxLefty

Actual tread depth is 7/32 for the fronts and 8/32 for the rears. Per Discount Tire.

That's an all season tire.

I've put about three k on mine and I love them...Grip hot is out very good cant say yet about under 40 cold but at 40 I know its a lot better than the good/craps...by a lot....

I've gotten as much as 45,000 miles out of the PSSs. On a Z51 Stingray.


They are what came with my '18 Z06, and at a bit over 10,000 miles, I see the same wear (or lack of), so I am expecting the same (ish).

Just installed a set of AS-3+ ZP's today from Costco. $1374 out the door including 4 new TPMS sensors, all reset and ready to go. Gonna rotate S to S every 5k miles to keep them quiet. Already got 7 miles on them and still very happy.

I had to wait most of last year to replace my original RF P/S A/S 3s. During the pandemic Michelin completely shut down most of their tire manufacturing. I now have the A/S 4s which succeeded the 3s. They run very smoothly and I recommend them to anyone who wants to drive their car year round when the temps fall below 40 in the winter.
