It looks like I can find 215/75R15s with adequate load capacity for my rear GAWR - definitely not Michelins, though. I almost wish I had 16" rims so I could run 215/85R16s, which are narrower but very close to the same diameter as the 235/75R15s and still have good load capacity.

I guess the 30x9.5s would only be about 6 mm wider but an inch taller than the 235s. I'd still have to change the speedometer gear. I'll run the numbers and check prices this afternoon - thanks for the idea.
