    It kinda depends on what size tyres and wheels you have .......

    I find that running 38 in the rear without any load in the back burns the middle band of the tyre!
    Im running my rears at 30psi and so far seem to ware even but ill come back and update if i change my mind

    It softens the road shock transmitted through your front end.

    After lots of experimenting I've settled on 24 front and 34 back. It still feels good out on the country roads and very comfortable in town. Mind you I don't carry heavy loads or tow with it. Got a Patrol for the mucky work.

    I run 28 front and rear on 18" Wranglers when running unloaded:) Tyre wear is nice and even across the tread:D Upping the rears to 38 tomorrow though as I'm loading booze for the kids. Off to the yUK on Tuesday:(

    I'd certainly drop the rears to 34 straight away then play with your fronts and see what happens. Rangies react differently to different tyres, I've got Scorpions on the front at the moment.

    Ive got 34 in the front and rear, and im running general grabbers at2s 255/55/18
    anything less on the front feels to "wallowy"

    Sorry mate but it depends on so many things;
    what's your driving style? I drive a Sprinter, usually at high speed, through the week so I quite like a fairly soft drive at weekends when I take life a bit more slowly.
    The state and type of your shocks will have an effect. Old, soft shocks will give a totally different feel to new gas shocks.
    Where do you live? Do you need to climb out of a quarry or down a farm track to get to a road?
    P38s can give totally different results depending on the make and model of tyres. The 28/38 given in the hand book was on Pirelli Scorpions that are no longer available.

    So all that you're really left with is doing what we've all done. Start with the handbook recommendation and adjust it to try and find what suits you whilst keeping a close eye on your tyre wear. As I've said before, if you don't tow or carry loads then I'd drop the backs to about 34 straight away. After that it's over to you.

    ps WTF are you doing up at 4am?

    I have 19" Range Rover Sport alloys on my P38, with brand new General Grabber ATs.

    I have been running 28/34, but do you think I should amend this due to larger wheel diameters?

    Following this as I also have 19s with 255/55 19 Goodyear Wrangler Duratrac being fitted as we speak! They will be set at 35psi while they settle, bit would like to know what works best for maximum winter weather grip while reducing wallowing on everyday roads.

    You need to have a differential in pressure front to rear to keep the viscous coupling primed. If you have wallowing on the road change the shock absorbers. Mine is on 19"s and is planted to the road, I use 30 front and 36 rear. .

    Thanks wammers, I'll remember that when next at the petrol station.
    Having matching tyres made a big difference to the "feel", but now have to make sure it's at std height before moving off, as it sounds like a slight rub on the wing liners when turning. A bit of persuasion with the heat gun, if it persists!
