You're correct I didn't , brain fart
Shelby CS40
285/30/20 Nitto NT555
I'm looking at going with a bigger tire
A 305/35/20 drag radial. I just don't know if it will fit.
Will fit just fine if you don't mind a little sidewall bulge. I ran 305/35 Nitto NT555r's on the 10" wide Shelby Alcoa super snake wheels and was content with the fitment. Again, slight sidewall bulge but they looked just fine to me. I also know a local guy (007snake) who runs the same tires on the wheels you mentioned without issue.
