Bed to tire clearance with 16.00's

[Lonnie]

Putting a Deuce bed on my M818. Will additional spacing be required between the bed & frame to keep the tires from hitting the floor?

If so, what are you guys using?

No ideas?

Has anyone with a M813 had issues with tire contact with 16.00's? during articulation?
I know the rear axles pivot quite a bit, but was not sure how much everything moves under load.
