Well, I went ahead and ordered the "Kooks" (I think that's what we should call them). You can't beat <$90 per tire installed.
I got the P205/55 because I was scared to go with the 225s on my 6.5" rims. I hear the sidewall isn't that stiff on these so they would probably flex a lot on the stock wheels.
Even in the OEM size the tread width is still over 1/2" wider than the stock RE92. The 225 tread width is about 1.5" wider than the RE92. I couldn't imagine another 1.5" width when looking at how the RE92s sit on these wheels performing very well.
