The Best of Corvette for Corvette Enthusiasts







On our 2017 Z51, we will probably get about 25k from the PSS runflats and 40k from the AS3+ runflats. Our GS and Z06 friends are getting about 2/3 of that.
Poll: How many miles did you get out of your Michelin OEM tires?

My first set was 35,000 on the fronts, 45,000 on the rears. My second set was 60,000 on the rears, and 60,000 on the fronts.
While I was having some Carbotech brake pads installed, I asked my tire guy why there was such a disparity between the oem and the replacement pair, and he said the tire manufacturers told him on more than one franchisee (or however that works for them) training session that when car manufacturers commission tires for production, they are allowed to custom order the compounds in the tire. They may use different compounds for the first part of the tread, which are softer than "after production tires." It is for ride comfort, and handling (specifically for test driving and early ownership), but the replacement tires come with single tread compound in order to increase the wear rating.
But the OEM tires are (even if they are custom made to the car manufacturers' specs), they are still called the same as the replacement tires from the tire manufacturer.
I had heard this as a rumor before, but this is the first time I had actually heard it from a credible source.
I've got 7,900 on my Z06 and the tread is just barely above the wear bars front and rear. The insides of all 4 tires show additional wear. I've never done a burnout, never tracked the car, but do a lot of spirited driving on back roads.
I have several friends with Z06's and they get between 12-13K out of their tires, but they are worn well beyond the point I'm comfortable with; especially on the inside edges.
I'm having a new set of AS3+ installed today actually.
Good luck with the 20+K some are experiencing! I've never made it that far on any of my vettes!


I run my camber as close to 0 as I can get it. I also try and keep an eye on the toe (Sneaky little bastard) as that will eat the tires too!
If you want to play, crank up the camber. If you want the most mileage from the tires, keep the tires flat on the ground.

Stopping at ~30,000 miles doesn't really help.

On our 2017 Z51, the codes are “tPc spec 1431” for the front and “tPc spec 1432” for the rear. If they have that marking, they should be as close to original as Michelin can make them. If not, ???
