Just chasing some opinions on normal bitumen road pressures for towing an off road camper van across the country.
It's running 265/75/16 Bridgestones. I've got 38psi in them at present.
Should I go a bit higher, trailer ways around the 1.2 ton mark.
Also, the Patrol's got the same size Cooper A/T's. What road pressures would people recommend??
Thanks in advance.

Tow the trailer and get the tyres up to temperature , compare the cold pressure to operating temperature and if the increase is 4 psi then you are on the mark.
Don't be afraid to drop the pressures to soften the ride while traversing bumpy or corrugated dirt roads. Don't worry about staking te tyres...if it's gonna happen it will regardless.

Forget worrying about the pressure in kpas or psis. The tyre is a pneumatic device and the more flexible it is the better is can absorb impacts either for it's own sake or that of the trailer. Obviously it cannot be so low that it willoverheat or suffer sidewall damage.
Suggest you inflate to the point that you have all but removed any bulge in the side wall.
Do it the same way on your Patrol. You will get good wear and ride and you will minimise stone impact through the tread.

Hi I tow my camper on road with 40psi and drop them to 30 psi for dirt roads and then down to 20 for the soft stuff or lower if needed and find that this works
well for me ,I keep them high on the black top to help fuel economy ,but keep an eye on them as if tralor is fully loaded the pressure will rise to around 50 psi once they start to heat up hope this helps Born to drive a 4x4 , not a keyboard

I tow a 1000kg off-road camper (an Ultimate) & use 35psi (the psi recommended by Ultimate) on bitumen & hard gravel
services.
Use the same pressures in the Prado (both vehicles use 265/75R16 Cooper ST's) in the same conditions.
The 4lb increase warmed up over cold is the way to
check what's right though.

Andrew,
We're running 265/75/16 Cooper A/T's on both GU and trailer. On the blacktop we generally run at about 40psi dropping to 30-35psi on unsealed roads/tracks depending on the surface type. On sand we drop them to 16-25psi again depending on conditions. Our basic rule is we run the trailer to the same pressure as the vehicle. After nearly 5 years of campertrailer ownership and only 1 blowout in all that time, we're pretty satisfied with our approach. Hope this helps.

Thanks Melissa
Just wondering what sort of wear/milage your getting. and do you put 40psi in cold or after warming up the tyres a bit?
cheers

Andrew,
We put in 40psi cold. Regards wear/milage we've only had the Coopers on so far for about 20,000kms but hubby tells me he's a little disappointed with the amount of wear so far. Claims we won't get 80,000km out of them. On the
bright side, they feel good on the car and have very little road noise.
A problem with the GU is that it is very difficult to get the alignment right and then it doesn't seem to take much to knock it out again. In fact, we went to several
places before we found one that was able to give us a good alignment. Result is that the Coopers are wearing on the outside. Hubby is trying to manage it and maximise our wear by regularly rotating all the tyres between both car and trailer, including the spares.

Andrew I have been using our CT for the last 10 years, covered some ruggerd country and found the following tyre pressures work
well for me - Patrol GU 40LBS front and rear for the blacktop from cold and the CT the same. Dirt/corrogations 28-32 lbs for both, Soft sand ect 20 - 25 lbs. My Coopers on the Patrol have exceeded 80,000kls and have run them on 40lbs for most of their life. But I rotate them every 10,000 kls.
The Coopers are good and fare much better than the Kumhos did which fractured the first time they saw some rough terrain!!
