A lot depends on loads and what you're doing.
Offroad I drop to ~ 15psi, on-road through the week 32 rear, 30 front. When loaded at the weekend or for towing I pump rears up to 36 and front to 32.
Every so often I cba to fafff and leave them at 30psi all round. Very little differences in handling that are probably more psychological ('cept the off-roading) and make me feel better.
These pressures are on BFG AT's 31 x 10.5 x 15. Last set lasted well over 40k, and were sold on ebay with ~ 6mm tread for £180 ... though the edges were rounded and pretty crap off-road ...

I run them low off-road mostly so the tyre spreads out a bit more and the tread can grip better, it almost softens the rubber (wrong terminology, I know) allowing each sipe and cut in the tread to move a bit and grip the ground better.
On my trials bike I run down to 4psi ...
15 psi still keeps the height in the tyre and is enough pressure to stop the sidewalls getting crushed against the rims.

Should say ... I don't always drop tyre pressure off-roading. If the car's full then I just leave them, the pressure drop is for when I want to try 'awkward' stuff and normally when there's just me or with me and a co-driver.
Depends a lot on how you like the ride comfort, using 235/70/15 's I find that anything more than 32psi at the front make's for a "firm" ride and every pebble can be felt so normally run at 30psi, as for the rear I've got em at 33psi (no towing).
The indy LR garage local to me reckoned I should run at 32psi all round. As it is though I've got nice even wear on the tyres with the current set-up.

You haven't said what vehicle you have Gouman. Different models have different recommendations! :boink: :drum: :scratching_chin: :fighting: Hey, have there always been this many smiley options?

No, but it keeps our mind's off what's wrong with out LR's
, failing that spirit's (not the transparent, spooky kind) help.

There's a lot of personal preference involved with tyre pressures. I was once told 24front and 26 rear by a tyre fitter for a disco which was clearly bollocks. On standard sized tyres I'd be looking at 30+ for road use, les for offroad. I'm currently on 265/75 bfg muds and run them at 40psi all round on the road. They've now done over 50,000 miles and are evenly worn. If I let em down the handling goes tits up and they get noisy.

Land Rover say: For 235/70 R16 tyres, Normal-all road conditions, Front 26 psi (1.8 bar) Rear 34 psi (2.3 bar).
if your putting 15psi in and its enough to keep the correct height then your pressure gauge is nackered cos 15psi hardly moves mine and that pressure would get ye a fixed penalty...if you got stopped.I run them low off-road mostly so the tyre spreads out a bit more and the tread can grip better, it almost softens the rubber (wrong terminology, I know) allowing each sipe and cut in the tread to move a bit and grip the ground better.

What you on about? 15psi OFFROAD ... who's gonna stop me and do me?
If your pressure gauge doesn't move at 15 then I suggest you get a good one. My low pressure gauge only reads to 50 psi, and can easily be seen. My digital gaues can also read 15 psi easily, indeed they measure down to 0.1 increments and seem to be as accurate as any other gauges I've tried.
Anyway, a pressure gauge on a tyre is only a comparator ... so long as each tyre is even with the other on the same axle then that's good enough. Occasionally I'll raise or lower pressure from 15, depends how it feels when offroading, and the actual pressure is immaterial.
oops sorry i misread your thread i thought you had said sometimes you left them at 15psi for on the road...
I run 39 all round in my 300 and it makes a firm ride but great MPG. Drop them down for off road mud work though. High pressures are good in the snow as it gives a crisp response and help keep a new cutting edge in the snow. Ask a Scandinavian rally driver if you ned more snow info. My td5 seems to like 36 all round as this is not to harsh yet gives better mpg.
