Tyre pressure on 255 55 r19

What should the pressure be for every day and full loads and does the difference between front and back affect the slip diff???

1. Pretty hard
2. Quite hard
3. unlikely

I have a sticker on my B-post with tyre pressure info, has your seat-belt scratched yours?:behindsofa:

34 front 36 rear normal. Loaded to gross weight 36 front 44 rear.

Ok was wondering what people run as I am in a band and weekends have heavy loads. I am running 36f and 40r at the moment from today on a trial as I sometimes get a lumpy feeling (possibly diff) like driving over thick white lines on the road that lasts for about five seconds then disappears. Looking on other forums it suggests this may be the diff due to tyre inflation?? They were at 33f 36r. It happens both under heavy load and with just me in the car. Every weekend I have about 150kgs of gear on board plus two passengers??

What model RR do you have? Does the rumble happen at specific speed? Slight uphill gradient etc?
Might be a gearbox problem.

It's a 2007 tdv8. Can happen any time on flat or uphill. Only lasts about 5 seconds. Not so much a rumble as bumping as if driving over white lines in the road every second then after a few it stops!!
