Tyre pressure ?
Range Rover Blues:
Run them at the standard pressure. They look podgy because they are very wide on the rims, the wider they go the less tolerant of over-pressure they will be. It's going to handle like a cow simply because of how big they are.
The owners handbook also says you can reduce the rear to 32 if the car is empty, so it's 28 front and 32-35 rears. If I run mine any higher it slides about too much so I know it's about right and I have the exact same tyres you do.
Did you know you can damage a tyre by running it too hard? and I don't just mean the tread wear. It causes something called a concussion punture, more like a blowout in practice.
buster uk:
thanks for the help guys,been running around this week with them all at 40 psi.I must admit it does drive better than it did when they were all at 30 psi.
So if i apply the +7 psi for mud terrains to standard pressures then i should be running : 35 psi front and 42 psi rear.
Do you guys think i should try that ?? actually why are the pressures higher for the back ? also i noticed that it was the back that looked more podgy than the fronts at 30 psi.
Jonny Boaterboy:
Dont know if this will help but I have 245/70/16 BFG alltarains on my Range Rover (same year as yours) I rang the tec line that is advertised in the magazines, (cart find there no. at the moment!) and they told me that 6psi above standard is about right. So if I were you I would go with the 7psi above standard which would give you 35psi front 42psi on the rear's. and then drop them to when off road-en. I would'nt run them the same all round. will post the no. for you if I find it.
Merry Christmas
Range Rover Blues:
They are higher at the back because the back of the car is heavier, is that not obvious?
If you want to run the tyres at higher pressure than recomended by the vehicle manufacturer then it's your funeral. I would suggest you try starting at the recommended pressure and try increasing them steadily so that you can observe the effect is has on handling. I run mine at 28/29 front and 35 rear, my car weighs 2,360kg empty!

Not strictly true... it's usually lighter unless you have something in it :) (which, for the likes of me includes a ton of junk at the best of times)
