How much front tire to cladding/bolt clearance is needed for off-road?

It sounds like it is too close, to me. Find something to drive on like a ramp to test your flex out a bit. If you place a rear tire on a tall curb or cinder block it will force a front wheel a little higher into the wheel well by greater body weight transfer. You could even use a floor jack to force some flex to see where you're at as a start tho. In my experience the worst rubbing usually comes from reversing.

I put 31" tires on my VX before any lift. Trimming helped clear them (barely), and I never had any trouble off-road on on.

Pull one of the hex head bolts and go to Lowes. Replace all that are in the 'danger zone' with pan head. They don't stick out as far and have a smoother edge so they won't damage the tire as much if there is contact.

It's funny that you mention more interference whilst in reverse. I've noticed that too.

Ditto here...mine only rub slightly when I turn hard to back up my driveway to put her into the garage.
