Looking for suggestions on tires

[bhays]

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.)
