Interesting. There are a couple other companies that sell 33x9.50s if you are really interested, or at least they use to...
This mud terrain SXT use to be available in 33x9.50R15, not a bad tire although it is really more of an aggressive all terrain, pinned for studs. It would work very will studded and siped for winter, I use to see them quite a bit in Oregon, owned a set myself in 31x10.50.

But like I said, they look like pizza cutters on a lifted truck in 33x9.50. I use to see them on lifted Toyotas quite a bit.
