If you are talking about cold traction, then yes - the more surface area that you have the better. And, "cold traction" = pretty much ALL street driving. But, if you are talking track/autox, then not really. It's better to have a 245 street-legal compound at temp (205-215*F) than 315s at 150*. |

I’ll be looking for a set of all season tires for my new ZL1 A-10 (assuming it ever gets here) when the Goodyear’s begin showing significant wear. That assumes someone (like Michelin) makes the stock size and stock speed rating at that time.
Both my wife and I will be using the new car as a daily driver.Where we live there is often very heavy rain and the roads are covered in water.Hydroplaning is a big issue for us, and I suffered through the Goodyear’s propensity for hydroplane on my 1LE.The new Goodyear’s on the ZL1 may be better, we will see. That being said, I fully expect to need another set of appropriate tires/wheels should I decide to track the car.

Completely agree, the MPSS's is what I switched to. That picking up grit/objects comment is right on!

Wow! 10K-15K miles. I never got more than 8K with my Michelin Pilot Sport Cups or Pilot Sport Cup 2's (different car, heavy foot). I would love to get Bridgestone Potenza RE-71 as a separate set for AutoX if I can get sizes that fit.

MPSS and MPSC are not the same. SCs are right at the mileage you get.

There is a lot of talk in here from people with no experience swapping tires on ZL1s and the like.

They will get greasy after a few laps. The Goodyear is a much better track tire.

...A michelin with a rating of 400 lasts twice as long as a Michelin with a rating of 200. But this won't necessarily be true when comparing to say a Goodyear. |

Somewhat correct. Be careful of the absolute "only"

In the world of a track rat, the ratings play out in performance, and there is some level of consistency between manufacturers IE one tire rated at 200 is going to perform within reason how another will. Again within reason. There are other things that have an effect. A tire with a tread rating of 100 for autocross, has a different heat build up rate than one designed for road course, and although they have the same rating they are designed for different applications. That is the one area that you might find tread wear ratings don't apply to well. Those two tires don't interchange application very well although the rating can be the same. The other area is how they handle heat, and the optimum design temperature. This is an area where the stock goodyears have some issues, both good and bad. They need heat to work well, and no amount of street driving will get them up to the proper operating temp. They need a few progressive laps at the track to come up to temp. Good at the track, or on the road if you warm them up. Bad if your leaving cars and coffee on a cool sunday morning and decide to show off with TC turned off. In this area you may find that different tires with the same rating may have some different qualities at temperature IE a 200 TW rating that lasts a few laps and goes off, or one that last the whole session. But in general any manufacturer that you get a 200 TW rated tire, you expect a certain level of traction. |

I am using the 315/30/20 Toyo R888s. They are amazing.
