The tires are Toyo MT's E rated on 16" rims and they are 305's. I had 315's on but downsized a little. I am not sure what the rim is since it was in 2007 that they were bought and they are either old Mojaves or some other brand because I think the rims are powder coated. At least when I got new tires on they peeled a little of the powder coat off by accident around the center hub.
Also the 4x4 is an SMB conversion so using a front Dynatrac axle open and the rear is the standard semi float with 4.10 and L/S in the rear.
I don't have any ARB air lockers installed.
Even on ice this beast does well simply because it is so fricken heavy. We have an ice storm today and everything is covered in pure ice. No problem the van sticks to the roads like glue. Tons of cars off the road everywhere.
Here is closer look at the rim and tire.
