Staying NA, get some good 215/45 17, adding a bit of boost, go 235/45 or 245/40.

I'd recommend you don't put 245s on an 8" wheel, as this is pretty pinched. 225/45R17 or 235/40R17 are the correct sizes on 17x8" wheels. For 245/40 you really need 17x9" wheels. Yes, a 245 will fit on an 8" wide wheel, but it's the minimum wheel width where it's even safe.

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.
