I assume its a 4x4 then it would have a 6x5 1/2 and I would go with a wheel that has a 3.75 bs or less

man thats sticking out there... would be wise to get the steering box brace as well..

8-10" wide rims are recommend.. i have ran that tire on a 6.5" wide rim.. centers tend to wear faster...

i have had 16x6.5" with 5.125"BS rims on my truck no problem clearanceing the leave springs
and there is plenty of room ona  3/4 to run 15" rims

yep with nothing else changes  the differnce between a 4"bs and a 3"bs is the wheel will stick out 1" farther on each side..

this will aslo cause increase scrub radius and force need to turn said tires.... cause more flex/pressure on all steering linkages..
