Tyre Pressures B/Stone D694LT's 265/70 R16

Hi Rat72

Not a Nav D22, but on my Prado, I run the 694 LT's 265/65 R17 at 32 psi front and rear. I then go down from there on dirt roads.


Cheers

Silly tyre shop!

Closer to 30-32 will give you a more desirable ride and tyre wear

HI mate, im shopping for these at the meoment for my BT50.

Could i ask the price you paid per tyre??

I've been quoted $309 fitted.

Cheers

Any thing less than 40 psi on dirt or the black stuff and you are kidding your self, this info comes from over 700,000 km of driving with them without a puncture.

98 % dirt roads and travelling.

When we had our D22 I run 32 front & rear
I also put 2 full sandbags up the front of the tub to even the tyre weight.
( 1100kg's front and rear from memory )
The sand bags helped a lot, with the lowsy ride, but then again I had modified the rear springs, for height and ride as well

Buggered if I would run 40 "neck breaking" psi, in the rear, except it I carried a tub full of gravel, or soil, or something like that.

Hi Rat 72,

Ive got the same ones on my Pajero. I run 32 psi on the blacktop and for the occasional dirt stretch.

If I'm doing some longer/ rougher dirt, I'll drop them to about 25 psi. Its only an approx cause of the different weights on the car. I'm looking for a bit of sag and (when you push the car sideways) a bit of flex in the tyre wall.

No one pressure figure will give you what you want and you'll need to adjust the pressure to suit.

You want them to last you run them at the tyre placard pressures plus 2-4 psi and never lower unless on sand , your little bit of "rough ride" will disapear after the tyres are broken in [ 1-2 thousand klm].

There is more to consider than comfort when selecting tyre pressures. Too low will damage the tyre and compromise performance, too high will not only be uncomfortable but can be dangerous as well. Too high can also be damaging to the tyres.

My vehicle is different to yours but this will give you something to think on. I normally run about 36 to 38 psi on the road. When I do a long blacktop run in regional areas I increase that to 40 or 42 psi. This has always worked well, feels good and provides good performance, tyre ware and I have not had punctures or tyre damage at these pressures while on the road.

On a trip up the coast last year I decided to take an alternate route to avoid traffic. This route took me over some secondary sealed roads which were in poor condition. This made for an uncomfortable trip but when it started to rain it was like driving on ice. Scary stuff. I pulled over and dropped the pressures by 25% to about 34psi. It was more comfortable and a lot less scary.

I have a simple system for determining tyre pressures. I follow the tyre placard and run at the max pressure listed while driving around town. I bump this up by about 10 -20% when on a long trip on sealed roads. When I leave the highway I drop by 25% every time the road surface deteriorates. So assuming I am at 40psi on the highway I drop to 30 on good dirt, about 24 on poor dirt and about 18 on the sand. This is a guide not a rule. At each point I take notice of how the car is performing and adjust pressures up or down to suit.

I drive Pathfinders at work some of which have 694's the plackard says 36 and that is where I go. I guess the Pathy is probably a bit softer ride than the D22 but the plackard is the place to start.
