So I went for the BFG M/T 235/85 16. They seem to fit the truck nicely and at overall weight of 7000lbs they are all, front and back, at 43psi to start.
Too bad no Michelin’s for the terrain available, the ones on my MasseyFergerson have held up well.
The only detail to work out is the storage. In the cage as is wasn’t even close. These tires have too much tread. Not wanting to be in the position someday of a roadside change and a difficult spare, the plan is to modify the cage starting with the forward bolted hinge and maybe the sides. When the weather improves ill pull that off and check it out.
