Deflate trailer tires

[4wd26]

I will drop the front pressures lower than the rear

Whatever the rear is is what I'll run the trailer

Mind you the caravan at 2 tonne is around the same Alex weight as the rear of the vehicle

Towed this way all over Fraser, Moreton and teewah beach

I would start at 16/ 18 and go lower as required

Sometimes way lower than what some would recommend
You can do this

If you know what you are doing

Thanks everyone for your help ill deflate[ATTACH]29774[/ATTACH] same as rig [ATTACH]29775[/ATTACH] the Rain is setting so not even sure ill end up riding

with any 4 wheel drive vehicle you Must have all 4 tyre pressures set at the same pressures, not say 20 in the front and 30 in the rears as this gives the Drive Train a BAD ratio to work with . 2 wheel drive cars can have any front to rear tyre pressures as we know but NOT 4 x 4 vehicles, the transfere case etc gets very upset .

Sorry mate but you a wrong! I have done thousands of km running different pressures front & rear without any machanical 'upsets'.

Two points to consider;
1. You should only use 4wd (with centre diff locked) on low traction surfaces - by the nature of such surfaces, your not going to get drive line bind up.
2. I normally run higher pressures in the rear to offset the additional weight in the rear (ie 25psi rear, 20psi front) and so that both front and rear have a similar amount or 'tire bagging' (and therefore a similar rolling diameter)

The late Adam Platte of the Pink Roadhouse @ Oodnadatta also recommended to me personally a few years ago that you need to adjust tire pressures to match both the road surface and axle load.

Completely agree!
All tyres have have a rolling circumference. Changing tyre pressures can never alter this rolling circumference, all that happens when you lower your pressures is the tyre flattens out at the bottom and the footprint lengthens.
I too run different pressures front to rear when heavily loaded - onroad or offroad.
Cheers, Dan.

Yup! We run 20psi front - 26psi rear & 20 psi in the CT (straight from Adam Plate's tyre pressure mud map for our car & load)

We've done a LOT of km's on some very ordinary dirt roads & never had any mechanical issues from running uneven tyre pressures.

so would it be fine to run 16 inch rims on the front and 18 inch rims on the rear and go 4 x 4 driving around the country ? would there be any upset in the drive line ? would there be some difference in the wheel revolution as in front versus rear.? i say Yes to all.

Rim size is irrelevant - tyre size is the issue. Get the right size tyres on the different size rims and there won't be a problem.
