Psi? - Land Rovers Only

drum655 · 02-25-2006, 10:14 AM

what psi do i need to run my 265/75r16's on a D2 to get the best gas mileage on the road? 40? or higher?

Disco Mike · 02-25-2006, 10:41 AM

I have been running 40#'s front and rear for 3 years on my 265 BFG MT's. I believe anything over that is over kill and will cause the center tread to wear faster then the rest of the tread.
Hope this helps.

Your tires don't state to run them at 65#'s.That # is to let you know the max. amount of air required to carry the max weight for that tire.
65 #'s will beat you to death with a 265 and you will wear them out way too soon.
Stay down in the low 40's on the road and when airing down don't go below 18#'s or you may blow a bead on a DII.

My crappy 205/80's say to run at 50 PSI MAX, which I don't ever run. I run like 40-45 in all four, but with the new rubber coming, I would suspect I'll be running something similar.

in order to get the correct tire pressure for fuel mileage please see the drivers doorjam for the correct tire pressure.

All tests run for fuel mileage is done a

The tire has a warning. It states do not overpressurize at 50 psi,

Always consult the owners manual or side door for the correct tire pressure on any vehicle.

40 seems really high to me.
I'm thinking more like 30 is where you want to be at. On stock rims you can down to 12-15 for wheelin'.

50 is crazy, 60 is suicide. As pointed out,,these are MAX inflations. The atty's make 'em put that on there.

The factory door jam sticker, showing the suggested air pressure for both loaded and unloaded tires is what the manufacture suggests both for the best ride as well as saftey.
If you are looking for the best tire wear and gas mileage, ask a tire store manager. They will tell you that a higher pressure will improve the vehicle rolling resistance as well as tread wear.

What about bigger tires? Like now I have so very worn down 205/80 on the 16" wheel, and I keep them at around 45. I'm upgrading to a 255/65 set of tires, which will also say like 50 psi. Now that they're bigger tires, what then?

45 psi is 45 psi. i dont think the volume if air would matter.

p76rangie · 02-26-2006, 04:25 AM

The reason that you can get better fuel economy with higher pressures is that it causes less rubber to be on the road. Less rubber means less resistance, but it also means less grip and can cause the centre of your tyres to wear. The manufacturers recommended pressures largely centre on ride and comfort as well as handling. I find that with too high a pressures in the front causes the steering to be too light and handling twitchy. On a trip I will sacrifice a little comfort for less cost, but I do not run the fronts above 36 psi and the back above 41 psi. This is with 255/85/16 BFG MTs.
