When I replace the stock 235/50/18 tires, I'm wondering if I should go with that size again, or try something like 245/45/18s. The diameter for those would be about 0.6 inches less (about a 2% speedo error). I think 255/45/18s could physically fit, but most sources advise against going that wide on an 8" wheel. Or, I could go 245/50/18, but that's going to have a lot of sidewall height, which is the automotive fashion equivalent of wearing high-water pants. I'm looking to maintaining a decent ride, so I'm not really interested in going down to a 40 or 35 aspect ratio. Tips?

255/45R18, 265/45R18 or 245/50R18 is what I would run if it were mine. Nothing bigger than a 265/45R18 on a 8".

According to The Tire Rack, the ideal size-width for as 18 x 8 wheel is a 245/45/18. That is what I went with. Correct the tire size via ForScan. This is optional as going from a 235/50/18 to 245/45/18 is minimal.

If that is Tal's left front tire that he posted, then the rotation looks wrong.
Its true, that tire is on backwards and the tires are indeed marked directional.

245/50 is only a 0.2 inch increase in sidewall. I'd rather have that than more wheel gap with the 245/45.
