Author Last Post
THANKS GREG, I THINK THAT'S GOOD ADVISE AND I APPRECIATE YOUR INPUT;
HEY GEORGE

NO APOLIGY NEEDED MY FRIEND, I'VE HAD SOME MEDICAL ISSUES THAT I HAD TO TAKE CARE OF AND THAT PUT ME OUT OF CIRCULATION. I VALUE YOUR ADVISE AND I DON'T NEED TO MESS UP WHAT GM BUILT.
THANK YOU GEORGE
John,
Sorry I'm so late in responding but I've been very busy buddy. Anyway, here's the official wheel/tire sizing info on your C5 which I thought may be helpful.

WHEEL SIZE: 17 x 8.5 (front), 18″ x 9.5″ (rear)
WHEEL TYPE: (Standard) Cast Aluminum
Wheel Type (Optional):          Forged High-Polish Aluminum
Wheel Type (Optional):          Magnesium (bronze tone) –
Number of studs: 5
TIRE SIZE:   P245/45ZR-17 (front), P275/40ZR-18 (rear)
Tires, manufacturer / type: Extended-Mobility Eagle F1 GS High-Performance

Now, you state you'd like to suggest you NOT put 265x18's om the front. Fist reason, Corvette purposely puts 17" front & 18" rear. You're suggesting putting the same diameter front & rear which will screw up your handling. Doing this would require you buy a new set of front wheels that're 18". I don't recommend that.
One should always be sure the fronts are 1" smaller in diameter than the rear. Now for the tread width. I'd suggest you simply try and go larger on the width front and perhaps rear. To do that you need to talk to an experienced tire guy. He'll tell you what your factory rims will accept. Clearances shouldn't be a problem as any tire that will safely mount of your existing wheels will have amble clearances.
John, I would suggest checking with a tire shop locally.  They may even be able to give you a better idea if they can look at the car in person and check for the clearances that would be needed to run a larger tire. When I have wanted to put larger tires on pickup trucks, the tire shop was able to take measurements to determine what would fit based on the size specs of the tires I wanted.
HELLO FELLOW MEMBERS
I HAVE A C5 2004 CORVETTE AND I NEED TO GET NEW TIRES AND WHEELS FOR IT; CURRENTLY I HAVE 245X 17 IN THE FRONT AND 275X18 ON THE REAR. I WAS WONDERING IF I COULD INCREASE THE FRONT TIRE SIZE TO 265 X 18; I WOULD APPRECIATE YOUR COMMENTS OR IDEARS ON THIS MATTER.

THANK YOU IN ADVANCE
