Michelin makes an 1100x16 tire. They are spendy, well over $400 each.
For a cheaper alternative, Thomas Howell of Snake River 4x4 in Idaho 208-652-7527 has machined adaptors that bolt onto your hub and then you bolt a Gama Goat tire and rim onto them. The Gama Goa tire is 1100x18, 40" tall and 126" in diameter. This will provide and increase of 45 mph to 50.6 mph.
The adaptor kit is $400, bolt kit is $20 and used good Gama Goat tires and rim (NDT military treads) are $55 each.
Aside from the price being about a third of the Michelin tires (remember you need to factor in a spare - $695 vs $2100+ not including shipping), the other advantage is you can swap on your original 900x16 tires for show.
The Gama Goat tire will give you 13" of clearance under an M37 pumpkin, which should be the same on other Power Wagons. They do give a wider stance and stick out 3" beyond an M37 fender.
And of course a gear change will run more than the Gama Goat tires cost, at least.
This is probably the cheapest way to get a larger tire.
