Looking for suggestions on tires - Lateral-g Forums

I have the wheels picked out for my '82 Corvette and am ready to order, but I am running up against tire issues.

I plan on going with 18x10 in front and 20x12 in rear (adding flares). Going with Pro Wheels Scorpion w/ black center (car will be black)

However, I am having troubles finding tires for that combination. Stock diameter is 25.6 and I want to go about an inch or so larger to fill out the wheel wells once lowered) I found the Nitto Invo for the rear in 345/25/20 (26.6 diameter) but there doesn't seem to be an 18" for the front with anywhere near the same total diameter or profile. There is a 285/30/19 (25.8 diameter) that will work, but I really wanted to go with 18's up front rather than 19's. Any suggestions? I can get the Nitto combination for around $1500 and sort of want to stay around that budget.)

I would go with 19s in the front if it were my car.

It's looking like that's the only option anyway. I don't hate the idea.. just always had 18/20 in mind.

Ok, armed with new information on factory diameters from:
http://www.corvettefaq.com/c3/MoreBite.pdf

I now know that at least some years, factory tire was a 225/70/15 with a 27.4" diameter all around. I would like to be closer to that diameter, but the rear tire for the 20x12 seems to have really limited choices.

Here is my other option - Michelin PS2
Front - 19x10 - 285/35/R19 26.9 diameter
Rear - 20x12 - 335/30/R20 28 diameter

I am not really sure I understand how to read sidewall height and it's not listed in the specs. Would this combination look ok in terms of sidewall height and the front not being a wider sidewall than the rear?

So basically a 27" tall tire front with a 19" wheel and a 28" tall tire rear with a 20" wheel. One inch stagger in diameter of tire, and wheel, so your side walls will match from front to rear. You're looking good.
