And how this thing is going to pull more G's than a Grand Sport?

I'm only wondering because the tires look so small.

Tire technology has improved. You don't need gigantic tires to accomplish the same result.

Word is that Michelin has helped out GM with some pretty amazingly sticky tires that allow for improved performance with smaller tires. Pretty cool if the performance is as good as advertised... smaller wheels/tires means less rotational inertia, less unsprung weight, and better hydroplaning resistance.

And the smaller they are (contact patch) the more efficient they are and less expensive to replace.

By no means are they small.

Amazingly sticky tires usually means amazingly short life span. It will be interesting to hear how long they last.

- Better tires
- Stiffer structure
- Better suspension geometry
- Better aero at higher speeds

Thanks guys!

I will be using the stock Z51 set up for the track and get some nice forged wheels for the street. 20x11 tire with nitto invo 315's should fit just fine and fill out the gap :-)

They are when compared to a ZR1.

Same width as a C6

One thing I've noticed in all types of racing, is when you want more traction, you go with the skinniest tire you can find. NASCAR has asked Goodyear to tool up some 185/85-15 tires so they can get the speeds up in the corners. John Force asked for some skinny slicks for his funny Car, as he was blowing the tires off the wide tires he's been using.

Plus skinny tires just look great stuck under a wide fender.

No narrower.

Hell My Cadillac came with 285s in the rear. Come on the Vette should at least come with a 305 rear. It looks funny with that small of a tire.

Same width as the C6. 245mm front and 285mm rear.

The C7 is narrower then the C6 GS/Z06 with its 275mm front and 325mm rear.

True, but my understanding was that they were still acceptable street use tires. If they really had a super short life, then they wouldn't be very impressive. They might as well be DOT race tires.

Exactly!

And that "huge" GS 325mm rear tire is only 1.57 inches (14%) larger than the 11.22" wide 285mm on the stock C7, not such an earth shattering difference.

Tire contact patch area is only part of the equation, the down force and coefficient of friction between the tire and surface are also a tad important

The Michelins that come with the non-Z51 car have a tread rating of 300. That is great, and they will last longer than previous generation factory Corvette tires. So, they are stickier, weigh less (unsprung weight), and are quieter than the previous Goodyears, and, they last longer. Win/win/win/win.

I do not know the tread rating of the Z51 equipped tires.

Width:
245 front
285 back
same as a C6

Lay them side by side. A huge difference. I ran a 345 rear on my GS.
