I'm on 235/70/16 Pirelli Scorpions, and run 28psi front and 35 psi rear.

Well I hope i'm running on 28psi front and 34psi rear but then who knows... these pressures are taken cold first thing in the morning with a stick pressure gauge but as soon as the sun comes out the pressures can increase by one or two psi and if I use both of my digital gauges one over reads the other under reads compaired with the stick.
So what's the point of u quoting PSI and are u sure it's correct?

why do people run higher pressures at back, surley needs to be higher at front to compensate the engine weight?

i have about 3 bar in each tyre not sure what that is in psi. and most fords run higher in rear than in front duno why.

seems like 30 front and 38 rear is the most liked pressur eat the moment. i figure the higher pressure in the rear is for the rear 4-5 passengers (7 seater) or 3 passengers and a boot of luggage, plus spare wheel and derv tank (100kg full) open for critism but thats the most likely IMO

My D1 owners handbook states: 235/70 R16 tyre-pressure for normal all load conditions is Front 1.8 bar 26psi and Rear 2.3 bar 34psi.

I always thought the lower front pressures were to help the steering wheels get more traction.

very fair comment sirwingalot didnt think of that but makes sence

I tend to run 35 all round in disco with standard tyres and 30 all round with my 33x12.5s.
there is far more weight potential in the rear so the tyres are recommended harder, also like you say the fronts are set at the lower limit for better traction, but it depends how you use/load your car. my weight is distributed more centrally than as the factory would have it, so my pressures are set accordingly.
i havent experienced poor traction ever so i tend to run higher pressures, not just in the land rover. used to run around 34 in the front and 38 in the rear of my track civic to reduce resistance and encourage oversteer. the front pressure could be noticed as the front end did all the work, the rear was a random number almost cos the rear just trundled behind basically.
one thing that track work taught me was that tyre pressures are up to you, not what the manufacturer says. the manufacturers recommendation is a start point and then you can decide what characteristics you want to increase or reduce by altering the pressures accordingly.
i run my tyres hard in the 4x4 because it has never made a noticeable difference to performance ON ROAD and the reduced rolling resistance (which can be seen in the sidewall bulge) is worth saving fuel on.
cheers
