For a simple point of reference on wheel/tire sizing, wheels are measured in inches and tires are measured in millimeters. Section width is in 10mm increments. 10mm is .4 inches, so just shy of half an inch. Every section width increase requires a half-inch increase in wheel width to achieve similar tire to wheel fitment. A slight stretch is better than a pinch, typically.

For an 8" rim, 225 or 235 is ideal. |
I 100% agree "if" you are hitting the track, for a street car sizing can be a bit more "varied".
Pinch also has alot to do with which brand of tyre and the different width and sidewall characteristics.
I personally prefer a 235/45 over 235/40, I feel it has a slight advantage gearing wise and more comfortable for the street.
The most fun street tyres I ever had on my R33 were the 255/50 16 M/T drag radials on R32 GTR 16 x 8 rims, launching from the lights and on the roll was awesome, no, they weren't the tyres you used for the track, or the tyres you used for weekend drives through the twisties, they were perfect for the city though.
I would put 245/40 17 in the same boat as the Mickeys for city driving. They would also be fine for weekend drives through the twisties as well.
I've run 245 with varying aspects on 8" rims on multiple platforms over the years, no kittens or puppies were ever harmed.
Track tyre on a 8" rim, it would be 225 or max 235 as you stated
