Regarding tyre pressures, I have run them at 32/34 as suggested by Cupar Tyres but am now running at either 35/35 (no load) or 35/38 (with load and trailer).
The standard pressures are 35/35 so I cant see how a bigger tyre can take less pressure in it as suggested by Cupar Tyres. This is why I have upped them to 35/38.
I have also looked on one of tyre charts on Kwik-fits wall (michelin supplied I think) and that lists 2 tyre sizes for the D40, both have pressures of 35. Also lists 2 sizes for the D22, again using the same pressure.
I carry a 12v Compressor around (as BFG's are designed with running at low inflation in mind for mud etc) so I mess with them and have found it to be more comfortable at 35/35 or 35/38. I suggest that you do the same, checking for excess wear on either the edges or in the center band.
I concede that sticking to OE sizes would eliminate the hit and miss for tyre pressures on non-standard sizes.
