Tyre pressures

Hello

I've just changed a tyre on my 110 and therefore checked the tyre pressure in the manual (first timer). The manual says 28 front and 48 rear, can this be right??? The spare was set at 33.

48? Sounds a bit high hmmm, my 90 is 28 front 32 back... 30 is a good one to go with... go with 30.

The single pressure quoted in the manual covers all load conditions, if you run the vehicle empty all the time then you could lower it a bit but make sure the pressure is increased if you start hauling some weight around. Remember that a 110 weighs more than a 90 so you shouldn;'t use that as a comparrison (manual states that a 90 on 265/75's should be 35PSI on the rear, 40PSI with 7.50's fitted). LR spend a lot of time getting these figures correct and I have never had a problem with them yet.
If droping the pressure then make sure you do a check to see if the tyre is under-inflated otherwise you will start to get uneven wear (under-inflation results in increased wear on the outside of the tread, over-inflation causes increased wear on the middle of the tread). Also if you were to have a serious accident tyre pressures are one of the things checked and if they are found to be way out it could be claimed that contributed to the accident.
I always make sure the spare is over-inflated as that way it can be put straight on and the pressure dropped to match the axle onto which it is fitted, too low and unless you carry a pump you could be running uneven (it also allows for slight pressure loss while being stored).
