Bars, now let's see, there is the saloon, public, lounge and don't forget the snug.
Now I'm giving my age away.
The pressure for Nitrogen will be the same as air. For a full load I would suggest 2.8 front and 2.7 rear, this is the book pressure for 225/40 18" on a GT, although the 156 book quotes 2.6 front and rear for 16" and 17" wheels with 205/55 and 215/45 tyres.
When fitting non-standard wheels and tyres life can be a case of trial and error to see what works for you.
The pressure must be set when COLD.
