I run 30 all round on a 90 when empty or not towing, but if they were down to 28 it doesn’t make that much difference.
Up to 36 or so and they behave more like run flats! |

Assuming 16” then the stated pressures from LR for my 2014 are 30psi front & 48psi rear(65psi rear when fully laden)
You can go lower on the rear, and in fact I do - comfort is increased substantially running at high 30s. However you can find higher speed stability to be somewhat compromised with softer rear tyres; think big steering inputs while doing 55mph+ so bear that in mind. Of course bfg’s are not fitted by LR so the best pressures for that tyre may differ a little due to the tyre compound, side wall stiffness etc etc. P.s. I assumed you have a 110” based on your profile/pic 2014 Keswick Utility 2.2 |

Allways 35 in front, 35 in rear if not loaded or 45 if loaded. Eduardo

Another vote for 30 all round for general use, ran mine on that for nearly 20 years using both 235 & 265 tyres with no dramas

Quite a few different pressures there then, So 34/35 seems to be the norm not loaded and mid 40's when loaded
Sand driving as low as 10 psi, what is the school of thought here, should the pressure be put back up at the end of the day to protect the side walls and then dropped in the morning? 2016 Range Rover Autobiography 4.4 TDV8 2010 110 XS Utility 2.4TDCI 2010 Range Rover Sport TDV8 (gone) 2007 Discovery HSE TDV6 (gone) 1993 110 csw 200 tdi (gone) 1994 90 HT 300 tdi (gone) 1994 discovery 300tdi (gone) 90 hybrid 3.5 v8 (gone) Range rover bobtail 3.5 v8 (gone) |

I’m not sure where you are planning on going, but unless it’s the Middle East you aren’t likely o be running at 10 psi all day. At 10 psi you stand a real chance of cutting the sidewall on sticks and stones. That low is just for the really challenging soft sand in my view. For general sandy desert driving you are more likely to be up somewhere 15 to 18 psi and over 20 for anything that could be stony or rocky or where you can get up any kind of sustained speed. This is also dependant on the load you are carrying, tyre size etc. What’s right will come with experience.
You need to be changing your pressures to suit the conditions at the time. A convenient compressor set up and good deflator will make this much less onerous. 2007 110 TDCi Station Wagon XS |

You have to choose when dropping pressures what you want to do. At very low pressures you won’t want to be driving at any speed as the tyres will over heat. If you are sand driving day after day then there is no need to air up at night, just to air down in the morning. It won’t damage the tyre. You also may not want/need to go as low as 10, depending on conditions and tyres. I find that with BFG tyres that they need a fair bit of air out to even start to get the bigger foot print.
