I've always run our 90 and 110 with lower than recommended tyre pressures, particularly on the rear where Land Rover recommend 48psi for normal driving (light loads) in the 110.
I've had them at 34psi.
There are many online discussions about it, often with owners recommending that the ride is better with lower tyre pressures.

Recently we went on holiday in the 110 and as we were loaded up l increased the rear pressures to 48psi (Still lower than recommended when loaded)
The fronts were at 32psi and l increased them to the recommended 34psi.
And when l got home l left the tyres at those pressures.

Guess what? The ride is better. I think maybe with the lower pressures the tyre bounce conflicts with the shock absorber action.

It seems that Land Rover knows best!

Slight word of caution check max tyre pressure on tyres fitted before inflation to recommend pressure (example GG AT2 265/70/16 max pressure 44psi)

I have tried several tire pressure settings on my 110 and always end up coming back to the Defender recommended settings of 28 psi on the front and 48 psi in the rear which seems to work best for me.

It may be the upgraded suspension and larger tyres.
My 110 TD5 CSW has the standard setup with boost alloys. With the pressures at 34/48 it's less bouncy without being more jarring.
 
My mate persuaded his missus to let him buy a Series 3 as a second car "it will be a great car for family outings" he told her.
The first time they went out in it the bonnet flew off on the motorway. The second time it broke down and they waited three hours for recovery. The third time it broke down in the next village and they had to walk home.
The guy is still full of enthusiasm for the Landy.
His missus is less keen "it's not a suitable family car" she said to me. "It would be great if it was like yours" (looking at my 2005 TD5 CSW)
l think she may have been mis-sold.

I run my 90 at 30 psi all round, let them down for heavy mud to 20psi all round. For fully laden, 28 fronts, 42 rears, same for towing. Works very well, and always has done.
 
Well, l am talking about my standard 110 being better on road with the recommended tyre pressures.

With lifted suspension and 33" tyres this obviously won't work and you'd need to figure out yourself what are the best pressures to run, as he has done.
