Default Why 17 inch wheels in front and 18's rear

I am a new vette owner, and have done numerous searches to find out why our C5's have different size front and back wheels from the factory. I can understand the need for a wider back tire, but why not 18's all around?

Lots of C5's with 18 all around. You may want to keep the overall tire diameter of the rears at least 1/2" greater than the fronts to avoid AH/TC issues. Some get away with less but most do not.. If your a gambling person or don't mind turning off AH/TC every time you start the car go for same size on all 4.

It was in the visual design for the desired rake of the C5

i'm willing to bet the larger profile of the front tires has something to do with the handling of the car.

Default 17/18 yeah really, why indeed

I admit the 17/18 combo seems kinda lame compared to the 18/19 combo of the Chrysler Crossfire V6 turd, but I will definately be going bigger when I get new wheels.

Also I hate the look of my wagon wheels, even the C4 ZR1 later models had better looking wheels.

I'm going to go to 18/19 C6Z next year.

I suppose it all came down to what looked "cool" in design phase, be glad the C5 didn't have any lame minitruck type body mods of the 90's.

17/18----still better than 17 all around

Just recognize you need a smaller tire in the front of the car due to the traction control. if you put the same size tires all around the car will throw a fit.
