Poor tire alignment will cause wearing on the inside edges of rear and even front tires.

They have double tyres at the rear end so that they have enough strength to carry the heavy load or the public
Very low. The tyres are the rear suspension. My tyres say max 5 psi, but I have balloon tyres so I run 1 or 2 psi.
Firstly check that the tyres don't have uneven wear - the front tyres might be worn more than the inside than the outside or vice versa, if they are rotate with the rear tyres, provided they have even wear. Then check your wheel balance, this has to be done in a garage. Hope fully these steps should fix the problem.
If it's just the rear axle which has dual tyres, then the answer would be six. If both axles have dual tyres, then eight.
Trailing edge is the rear edge of a wing.
rear wheels are probably toed out and need an alignment
The torque which is to be transmitted in the tyres defines it
For standard tyres its 36 psi front and rear.
