Unless you're running a 19*12 wheel, forget it!

No way you can squeeze 325/30-19 on the rear wheels and be safe to drive them......
What's the biggest tires I can put on the rear 295?

Make certain that the overall diameter of what ever rear tire you decide to run is 1/2" to 1 1/2" larger than the overall diameter of the front tires to avoid issues with Traction Control (TC)............
Thanks man 👌

I have Nitto invo 325-30-19 on my 04 Z06 on C6Z06 reproduction rims 19x11. They fit with no rub. BUT!!! they touch the break ducts when the suspension is at full droop. no rub while loaded and driving though.

I imagine it could be done, I ran 335/30/18 on a lowered C5....it will probably be tight..

as mentioned the geometry is key to keep from having TC issues

What size wheel/tire configuration are you running on the front?

I'm running 325/30-19 Hankook Ventus tires on 19x11 rims in the back.
Tire Rack says these tires are good on rims 11" - 12".

As 8VETTE7 said, some members put 305mm wide wheels on 10" wide rims but that's pushing it, so 295s will probably work, too. However, if you check the Nitto chart JetMechZ16 referenced you will see that a 285mm wide tire is the optimal max size for the 10" wheel.
And, as 8VETTE7 and pewter99 both mentioned you want to keep the stagger to avoid traction control issues.

Roger that…but my issue is whether 325/30/19s will fit on 19x11 wheels on the rear of a C5 without any issues.

The tires will fit fine on the wheels, but the wheels will stick out about 1" beyond the fenders. To keep the tires within the wells in back, you'd want a 10" wheel with a 305/30-19.
Here are a couple pix of my 325/30-19 on 19x11" rims. I also added a 1" flare to cover them.

Thank you so much…looks great! What size wheel/tire comb on front? Sorry for all the questions, but I was told (by a wheel dealer) to watch the tire ratios or I will have problems with the ABS, etc.

For what it's worth, I have a 325-25-20 on a 20x11 wheel in the rear.

That said, I agree with most all comments that while a 325 wide tire can be mounted up on the OP's C6 wheels, it's probably not the safest scenario.

Good luck with your project.

That looks great! Did you lower it on stock bolts?

Yes, Lstyle01, it's lowered on the stock bolts (until I can save up enough coin to spring for some C/O's)

These are Nitto 325-30/19 on 11" wide wheels; about 65mm BS. Never has rubbed on mine, and the ducts are intact.

Not the greatest photo (as I didn’t have them on for long), but I bought a set of C6 base wheels and the rears has Goodyear Eagle GT 325/30/19s crammed onto them. I’m running 25mm adapter-style spacers on the rear and these barely fit without hitting the inside of the wheel well. In this photo I was not as low as I am now but they’d definitely come in contact with the fender if it sat any lower. Didn’t notice any drivability issues but I can’t imagine they’re too safe which is one of the reasons why I ditched them.
