18 x 265 (or 275) in the front and 19 x 305 in the rear seem to be a real popular sizes. No mods necessary. All sizes fit perfectly and look great. I'm running the above sizes but with the 18 x 265 front option. Very happy with it all.

Its hard to pull off the right "look" with anything larger than 19's on the C5. The tire sidewall just gets too small. Just my opinion though.

I have the 18" fronts and 19" rears on my 2003 Z06, running Michelin Super Sports all around in the following sizes:
265/35ZR18 Front
295/30ZR19 Rear
Ride is super and handles like it is on rails.

Your doing your homework before jumping into a big $$ purchase.
Thats better than some I have seen on here.
Good for you !
If you go with 18/19 then go with:
Front- 275/35/18 (or 265/35/18)
Rear - 305/30/19
If you go with 19/19 then go with:
Front- 275/30/19
Rear - 305/30/19
As for retaining vehicle value ?
I'm laughing quite loudly right now.
Where do some people come up with this crap huh ?

Toque nailed it. I will add that as soon as you are forced into 25 series tires (20" wheel) you will have so little side wall you'll create a shiity ride.

I do like some of the 19/20 setups I've seen, but it seems difficult to find a broad spectrum of tire makes with an adequate sidewall.

Ask me how I know!!!I researched the forum like crazy and heard all the warnings and still went with a 19/20 combo. Just liked the C5's I was seeing with that combo. So I went for it and also lowered it on aftermarket bolts, C6Z06 shocks and C6 Z51 swaybars. Ride was horrible! Lifted it back up some and got another alignment. Still rode horrible! On a perfect road it was fine but just couldn't take the harsh ride. Every pothole I would hit would knock the fillings out of my teeth and make me cringe thinking I just bent a wheel. So now I am in the middle of switching. I bought a set of 18/19 HRE 547r's with Nitto Invo 275/35R18 & 305/30R19 tires. Also installing a new set of Pfadt Featherlight coilovers.
On a side not, the factory brakes look tiny with a 19/20 wheel setup. they look so much better with 18/19's.....
