Everyone's car is going to differ a little bit, rarely is the experience the same for most people.
Is the car lowered? Have a back seat? Drag race only?

I run a 275 35 18 bfg drag radial, runs a little on the wide side. My choices are, rub on the outside with a spacer with weight or a passenger in the back, or no spacer and rub on the wheel well on a hard corner. (one of these days i'll put my panhard bar on to prevent this). Rubbing on inside is a lot easier on the tire. I could bang out some more space probably, but I don't want to.

My car is fairly low.

Not sure how that will link, but if it doesn't use the 1010 tire calculator to compare heights.
The 275 35 is close to stock height, then the next size you wish goes up nearly 1.25 inches, that is an absurd amount in itself on an 18, then the 305 40's go up 2 inches.

A 305 40 18 is going to be way the hell off, even the 285 40 is going to look like you were going for the offroad look. Even worse if the car isn't lowered. While I can't say for sure where it's going to rub ( I don't believe in 10 inch wheels on foxes without tub work), i'd bet you would have quite a few problems, probably everywhere. My 275's fit on an 8.5, so i'm not sure what a 10 does for someone.

I wouldn't exceed the 275 35 18. The extra width or height isn't worth the potential headaches.

Any particular reason you want tires that tall?

I'm a little more of a looks guy so i'm biased, I like the car to look balanced. That's a nice car, but those tires just don't look right to me. Maybe why he went shorter.

If you only drive in a straight line you can stuff pretty much anything under the rear you want, but here in NJ we have jug handles, take one on a little more than coasting and massive tires rub, one slice and you have a $300 paper weight. Back in the day I ran a bfg drag of a 255 50 16 (may have been a 55) and they rubbed.

If it were up to me, i'd find the look and function you want and change the gears.
You know how it goes, fix one thing break another.

What gears an trans you running?

Fwiw, I have a 275/40r18 toyo on the back of mine. 18x10 +25 wheel with a 7mm spacer, no quad shocks, eibach sportline springs, tubular upper/lower lca's and bilstein hd shocks (it's pretty stiff), and rolled fenders. It's snug, and it does graze the inner wheel well when cornering hard.
