HELP with tire size selection

What tread width and aspect ratio is best for a 20"x8.5" rim in the front? I agree that a 275/35/20 is best for a 9.5" in the rear but I need some advice for front tire fitment. Is 235/30/20 too thin? I care more for endurance and ride comfort than for aggressive fitments and performance. This is for a 3gen LS430. Please help.

The front usually has a higher aspect ratio. So if the rears are 35, the fronts need to be 40's.

Here's the best size to stay within spec:
Front: 245/35R20
Rear: 275/30R20 (actually, 285 would be closer to stock dimtr.)
