Well it depends on the tire brand. I have Mickey Thompson 315/35-17 currently and they fit and are big 315's, but recommend rolling the fenders. Plenty of room between my tire and frame. I fit the rear wheels off my corvette 325/30-19. They did fit and drive nice with the correct backspacing.
I did the notch to the seam. I'm probably moving to the Nitto tires that run small.The 335/30/18 Nitto should not be any larger than the Bridgestone 325/30/19 I already had on the car. The pic below is of the 325/30-19. If the Nitto on my 18x11 wheels with 5-3/8 backspacing do not fit, I will go to the Mickey Thompson 305/35-18. When the car is on the ground, they fit just inside the rolled lips and don't touch.

I only did the rears. I now have M/T 305/35-18 Simmons wheels on her. I'm still wanting to do 335/30-18 soon. But I will need to back half the car so why not build a chrome moly tube frame and go AWD while I'm at it... I have an R&D 86 Regal we are working on as the AWD project.

The rear is now 18x10. I re-hooped the rear. Was 18x11.
5.5 back spacing.
The fit is perfect with 305/35-18 MT
The front is 18x8.5 with 4.5-4.75 backspacing(I don't remember which one)

The plan has been in development for about 6 months.
We have a BW4472 transfer case built with a Mark Williams 32 spline input shaft to mate up to the 4L80E(4wd tail on my existing 4L80E)
The front pumpkin is from a Typhoon like the transfer case. The front suspension is c5 corvette with the c5 rear knuckles up front. The upper arm will need to be custom fabbed due to coil over location. It will be another year project for me.

Couple of questions for you:
What is the pulley setup for the SC?
What are IAT pre-TB from turbo to SC and IAT 2 post SC boost into the motor?
If you would share both low boost and high boost numbers that would be great for IAT2.
Thanks!
