Toyo makes a 33x10.50x15 Open Country tire
Toyo of all companies!
I wouldn't want anything much wider than that. Any wider and they get "floaty" on gravel and are less able to cut their own trail through snow.
BFG KO2 or General Grabber X3 33x10.5 r15................. Only downside is both are load C 6-ply rather than Load E 10-ply.
