tyre pressures land rover series III LWB

IME 28 - 30 psi all round on x-plys, about 4 psi more on radials should be close to right if it's empty, anything up to 45ish in the rear if it's fully laden.

Owner's book :- 7.50x16 crossply 25/25 up to 250kg load, or 25/36 loaded radial 25/25 , 25/42

Other recommendations vary up to about 28/60 loaded, but I would be inclined to stick to the book figures. Lower figures will give a better ride at the expense of handling, steering effort and tyre life and to some extent fuel economy, but except on soft ground don't go below about 22. (soft ground at low speed you can go to 15 or even 12 with tubes). Higher figures will give better handling, longer tyre life, lighter steering and better handling at the expense of a harsher ride, but don't go over about 35/45. What is best depends on how you weigh up the above advantages and disadvantages, but with some tyres, particularly radials with low ply ratings, one or two psi will make a lot of difference - you may find it worthwhile experimenting around the recommended figures.

I use 28-30 front and rear on 750's, except when Im lifting and towing a vehicle, then I take the rears up to 50, which is about what you should be considering if you take the full ton payload in the rear.
