OK tire experts, what size are these rear tires?

I guessed 325. I have some vague memory of one of the tire engineers at the Bash let slip about the fact a 325 would probably fit the C7.
This pic seems to clearly show front and rear are different size wheels, like 19/20. But most of the other pics we've seen I thought looked like the wheels were same size. Not likely I guess. Any other thoughts?

305 minimum.

That is a great picture. I have not seen that one before. It's the first one that I've seen that you can clearly see the brake vent in front of the rear wheel!! Can't wait for them to pull the wrapper of that beast!!

Michelins run a tad smaller in width compared to the Goodyears. Could be 325 or 335. I mentioned 305 since GM is using a smaller tire with very good results in the base C7.

That description I agree with. Of course, base to base they are the same size with the exception of any manufacturer-based variances.

I'm guessing 335/25-20 as the OA diameter must remain close to the OA diameter of the 285/30-20/ and 285/35-19 as used on the base 7. Might be 345/20-21 but I doubt it as they are just a tad smaller on the overall diameter.
Photo of ZR1 tires for comparison
I don't believe they are 325/30-19 as used on the C6 Z06 as they have much thinner sidewalls then the Z06's tries.

Suspension Basics Mach V motorsports
All Eclipse/Talon/Laser cars use a simple spring/shock setup with independent MacPherson struts up front, and either independent rear suspension or a beam rear axle (on 90-94 FWD cars).
Note that "shocks absorbers" are technically different from "struts", but both words refer to dampening tubes that serve to soak up motion from the springs, keeping the car from bouncing forever after a pothole. For the purpose of this article, all shocks and struts will be known as "shocks."
Lowering a car entails installing a shorter spring in place of the factory unit. Shorter springs are always stiffer than the factory springs, since a spring with the same spring rate would cause the suspension to bottom out all the time.
Because the shorter spring requires a higher spring rate, additional shock dampening is needed as well. Normally, both springs and shocks are changed at the same time for effective lowering.
Of course, lowering can also make a car look good, particularly when the car has larger-than-stock wheels. Because a larger wheel requires a thinner sidewall to maintain factory rolling diameter, the ratio of fenderwell gap to sidewall increases as the wheel gets bigger. A 4" gap between tire and fender looks okay when the tire sidewall is 4" tall, but when it's 1.5" tall, the 4" fender well gap looks funny. Lowering the car down a couple of inches makes everything look proper again.'
Appears someone that knows more about suspension setups than you, also uses the "wrong" terminology.
