The situation is this:
I went to change one wheel today for the spare as that particular tyre is more worn than the others due to a wheel alignment problem.
The last people to touch the wheels were a certain Perth Land Rover Dealer who rotated the wheels at a service.
Well...
As you all know, the torque for a D3 wheel nut is 145Nm.
My rattle gun (air) won't budge the nuts!
My torque wrench only goes up to 200Nm and it clicks out immediately!
I'm over ranting about these things so my question is this:
Do I go to one of the local tyre places and get the nuts loosened? or
Do I leave them until, i go up to Perth next weekend for some work to be done (new shocks and a compressor issue) and get the dealer to do it, bearing in mind that if I have a flat in the mean time, I'm stuffed?
Is it possible that the studes may be damaged from having the nuts put on too tight, thus if I have them loosened here I maybe even more stuffed??
help please?
TIA Have a nice day!

I think I'd be inclined to leave it to the dealer if possible, (just in case they have stretched the studs or damaged the threads on the nuts),explaining the situation to them, so they can (hopefully) check / rectify / pay for any damage. But carry a breaker bar (and if necessary, a piece of scaffold tube  ) and socket with you in case you get a flat in the meantime.

Jamo,
Every time my D3 comes back from a service I have to use a 5' tube on my socket bar to loosen my wheel nuts 
I pity the average owner who has a flat in the bush

The correct applied torque for a 8/8.8 grade M14 fastener is 112 to 168 Nm a breakloose torque of 200 by over torque could mean damage to the thread from, personally I would get the Perth dealer to change the nuts and the studs.
It is possible that the coating which has a know friction co-efficient, has been damaged. The key area is the underhead face of the nut to the top face of the washer. If so 200Nm may not have tightened the nut up fully, this is unlikely.
The opposite is very dangerous. Never improve this interface with oil or the like as you can drop the levels of friction to the extent you can snap the stud below the 168Nm. Formerly shiny moose
