alohasurftoad thank you for this. I had picked up on the height issue for 235/35 would cause yes. But not on the reverse diameter stagger that would come with 235/40. From a diameter & height perspective (which i think is really important to keep as close to stock as possible, as the suspension & front axle geometry would have been designed for that), yes 245/35 seems to be the optimal configuration.

235/40/19(26.4"), larger sidewall, better ride and impact protection with slightly less sharp turn-in. front wheel gap will be reduced 0.2" and front height will increase 0.2". the reverse diameter stagger will cause slight reverse rake though likely unnoticeable unless pointed out.

245/35/19 is the the best size for the oem 19x8 front wheel as shown in the posts above.
