mini tub
From a street perspective;
My stock 68 Barracuda tubs accept 325s with just the springs offset.
IIRC those are 13.6 profile on 10s , but 10s are really not wide enough.
Even my 295s on tens have to run down at 24psi for long tread-life. I got used to the rear steer and now I like it.
But, on the stock rear end location, at about 28"tall the front of the tire is getting a lil too close to the sheetmetal for my comfort, and spacers on the stock hangers are only good for maybe 3/8" more room. Some guys reshape that corner. So far, I've been getting away with the spacers.

whatever the mini-tubs and springs in frame, gave you.

But IMO, 295s are better for drifting, cuz with more sideways rubber, there is less drama and quicker/easier recoveries if/when I screw up... And 275s can be run on 8.5 wheels for lighter total weight, and can run 28psi for a long tread life and some say better street manners.
The biggest is 12 inch wide with a 7 1/2 back space
I'm thinking you mean 12" tread?
Ima thinking, that would be close to a 340profile; and, on the street, should probably be run on a minimum 11" wheel. I'm guessing.
