Based on available tire choices, I'd go with 17x8 TTII's with 245/45-17 on the front and 255/50-17 on the rear. They fill up the wheel wells, won't rub on the front at full turn, and they look wicked cool.

Anyone else with 17" front and 18" rear TTII's that could post a pic?
I am thinking about going 17x8's front and 18x8's rear although I swore I definately would not when I started looking but I figure if I can cram some 255/45R18's under the rear and 245/45R17's up front there will still be a bit of sidewall and a decent rolling diameter, the rear will actually be a perfect 27.0", same as original, the front 25.7" a little smaller than the 26" I was hoping for but the 550 front springs will hopefully lower it a bit in front to compensate......

http://www.corvetteforum.net/c3/themoneypit/I checked the American Racing website and there are offset specs also. What is correct offset?
Am assuming that I could go same route (16x8 rim and 255/50R16 tire) on my '80 with no issues. Correct? I like the polished rim and tall rubber look also.
This is the 16x8 that American Racing says is correct for the 68-82 vettes: http://americanracing.com/appguide/f...nd=icanracing#

I have 275/40 17s on the front of my '79. I had 255/50-16s before. Not much overall difference in size. My car came new with 255/60-15s, and the factory trimmed the fender lip slightly. I plan to put 275/40-18s up there soon. No problem's up front. Different story out back.

Am asking as there are MANY more tire options at TireRack for the 235/50R17's...

using it for the tire sizes you listed above -there is only a 0.3 inch difference in the diameter.
235/50R17 - 26.3" diameter
255/50R16 - 26" diameter.

Yep rim size, backspacing and tire size fitment doesn't depend on what style rim you choose, however, having said that I read a few posts that warned about caliper clearance on some makes of aftermarket wheels as they can interfere with the calipers on the C3's. the shapes of the spokes on the TTII's means there is no probs caliper clearance wise with them.

Lol I have seen more TTII's in every other thread except this one, I think more TTII pics were posted in that brake rotor painting thread 
Well I have been (and still am) undecided, it is either 17X8's all round or 17x8'x and 18x8's, I am ordering them today so I guess I will decide when I ring up to place my order!
Thanks for the help guys, and pics, even if they weren't in this thread

Whatever you decide, it's bound to look great - it's very hard to make a C3 look anything but great

I am weak, yes weak!This is what happened in the space of a week with regards to getting wheels:
1. "16's all round is the way to go"
2. "ok maybe I will get some 17" just for the rear"
3, "oh ok I'll just get 17's all round"
4. and finally "nah 17" front 18" rear, I am only buying these once"
omg
Yep so it is too late now I have crossed to the dark side and gone much bigger than I thought I would 17X8" front and 18x8" rear all with 4" backspacing, it probably didn't help watching a back to back marathon of 'rides' with them throwing massive rims onto everything
With regards to who I ordered them from I was going to go with Tomz Wheels purely because they are a Supporting Vendor, but even after following up several other leads Tomz Wheels http://www.tomzwheels.com/ was still the cheapest and their customer service was impeccable (so helpful via email and when I talked to them on the phone) triple thumbs up
