Tire Question ???
I have Goodyear run flat on my 05 and the fronts are shot. Got an alignment which is too late for the fronts. The rears are in excellent condition. Can I put these on the front and not have a problem 245/40/18 Dunlop Sp Sport 01 A/S DSST runflat. Don’t want to invest in a new set of tires yet until I see how this alignment works out.

Some people use mixed combinations like that and report no problems, but there have been at several first-hand stories posted here about a mix creating bad handling even during normal highway driving.
And if you start pushing the limits, either for fun or because of an emergency maneuver, then things can get very nasty very quickly.
You might be able to buy some used GY fronts and run them until the rears are worn, then replace all four.

The Corvette is not your normal street passenger car.
I would replace all 4 tires if a different brand was desired.
Ya the fronts are shot and you have good rears, tough situation.
For me my choice would be to put GY back on the front or buy 4 new tires of a different manufacture.
Maybe try selling the rears.
No mixing for me...on the Vette, this is a high performance car.
Also just get the Pfdat Street alinement to the letter and have no worries.

You guys are probably right however I've had GY's on the front and Michelin AS Plus on rear for 2 years without any problems at all for the same reason as op but reversed. My fronts were brand new and the rears were worn down.

Maybe I'm missing something. If, as you first mention, you have Goodyear runflats on the car what does a "245/40/18 Dunlop Sp Sport 01 A/S DSST runflat" have to do with anything? A 245/40/18 would be an unusual tire size for a C6 especially for the rear. Notwithstanding it's preferable to have an alignment done when you first put new tires on a car, assuming the alignment was done correctly and to factory specs I don't see why you'd wait to see how the alignment "works out." It should be good to go. 
Just in general, I would never mix runflat and non-runflat tires. You can, with caution, mix 'like construction' tires of different brands. I would suggest you keep to the more 'accepted' tire sizes for tire longevity and for best all-around peformance on the street.
