The tire pressure on the drivers door of my truck recommends 28 psi front and 46 psi rear. I would like to know what psi do you people recommend and use and also why does Land Rover recommend such a difference in psi between the front and the rear.

 

I run 40psi all the way around.
They say to run the backs so firm for when you are loaded.

 

I am a 40PSI member also. I rarely tow, or have the back loaded with stuff, and I find that is the best setting for tire wear and ride.

 

yep Me too 40psi a piece...

 

The handbook says 30 in front and 34 rear... it's correct ??

Correct tire pressure depends on the the GVW and the tire being used. Once you move from stock tires you can't go by L/R published recommended tire pressure any more.

 

Technically he is 100% correct.

But I failed algebra, so I just run 40psi making sure to read the side wall on the tire first so as not to exceed the TIRE manufactures maximum load rating and inflation pressure.
The sticker on the door jamb is for OEM tires.

 

The reason for higher psi in the back is there is more weight on the rear axle then the front. According to the jan2003 issue of car and driver the weight distribution is 47.1% front 52.9% rear.

 

Thanks for the replies. I will try the 40 psi all around and see if I notice an improvement in ride and mpg. I am currently running what land rover recommends even though the tires that I have are not the ones that came with the truck originally.

 

I picked up almost 2MPG (depending upon city/freeway/altitude/etc.) on a recent road trip by running higher psi. I only wish I took the advice sooner!
