I second the opinions on the the bird tires;
Determine your gear ratio (few things kill performance as quickly as tires that are too large).
Match the tire size to your gearing 33s -410s to 4.56. Higher gearing (lower ratio numbers like 3.31) will match to smaller tires.
Match the tread too the terrain; Street mostly/only; all terrain, Off road; mud tires.
Pick a width; this is very subjective, I prefer a medium width tire in the 12.50 section width range (about 9 3/4" of tread width) most of the time. For higher traction demands, off road, I go for a 14" bogger (but it is easier to break parts).
Finally pick a brand (BFGs have given me consistently very good performance and life). Interco tires, at least their boggers and super swampers, are generally known as soft compound off road tires that do not last well on the street.
...a well prepped, well driven, vehicle should do well in any terrain, including the highway.
Carburetors became obsolete during the last century... do what ever it takes to get fuel injection...It makes bigger grins off road.
