They have 31x10.5 R15, which is what I run now. There is a Walmart in just about every town in America. You didn't really name a downside in my opinion...
2001 Montero Sport XLS 4x4 I went with 285/75 r16 pretty close to 33's and tons of options out there. So far so good with my choice. See sig... I love the look. They aren't to loud on the hwy running at speed either.
Just installed some Cooper 285 75 16 AT3s and I'm very impressed with the almost zero noise and wet weather stability. Technically a 32.8 though lol. Gen 3, no lift
I will play... 255/85-16 on stock wheels 2" lift. Do great on rock, mud and snow! Not worth a crap in ice, but then again, what tire is without spikes.
