yar sorry for the bad quality pics,,, i have a poor cam in my handheld and the insuffecient light was another reason... will post pics today in sun light....
yes there are red stickers, only two on both sides of windscreen frame...
There are two reasons to put on the tyre on driving side.... i have put in both spare tyres and jerry cans on opposite sides of the rig to balance out the over all look of the mutt.. i tried this tyre on passenger side while installation but wasnt looking nice.. moreover if we put the tyre on the right side,, gate cant be open completely coz of the large diameter of tyre with stops the gate to open it completely...
as far as weight on hinges and latch is concerned,,, thats not a problem as the gate and all its accessories are strong enough to bear this weight..
but i beleive that you are right on point of rotation thing... will check it out with and without tyre on back and let you know...
