To those of you who take your VX off-road into the "big stuff" .... how much clearance is needed between the tires and the front cladding and the BFH bolt at the back of wheel well?

When I'm on flat pavement and turn the front wheels to position the tires so they are as close as possible to the cladding or bolt I have about 1/4". Is this too little? Should I trim more cladding / BHF more bolt?

I just don't want to discover that should have prepared better before I left home.
