Suedehead:
So whats the problem with the 7.5 tonner and the tyres .
Is it because the straps are secured to the side raves ?
In Germany , Straps twisted, Straps over the side boards, no strap protection on the edge of the side boards, straps should have gone between bottom edge of side boards and the deck,the gap between the stacks of tyers should have been filled out with Pallets,Here you would have not moved another inch with that, Just Saying 
Oh and the the strap in the Right of the Picture has got a knot in it
