Hi... Can any one help please... We have just obtained a 2015 Sorento KX3 and cannot find what the tyre pressures need to be whilst towing. Been doing a few searches and I'm still scratching my head. Spoken to dealership and they say "follow the heavy loading in the book/door plate which is 33psi all round but you can inflate the back ones a little higher. Not a lot of good. What do other Sorento owners use please as a guideline.
.
Thanks.
Alan

The usual advice for towing with any car is to set pressures at fully laden as indicated usually on plate in front door frame. I can't see why that should not be correct for towing.

If not in door frame try filling cap sealing panel lot of cars have here.
Usually 3/4 kgs more in rears for towing depending on car

IMO increasing tyre pressures on tow vehicles rear ends is far more to do with increasing the vehicle's stiffness so making the whole unit less prone to instability, than it is to do with load carrying. The latter, though must be within its limits.

JTQU, I think you are right. After all does anybody ever worry about pumping up the tyres when an adult gets in the back? You're only going to load an extra 75kg or so on the back.

Some cars don't need tyre pressures increasing for towing.

We have a 2014 Sorento, I leave the tyre pressures the same at 33ppi when towing. Looking at the door plate the symbols give the car fully laden with a tyre pressure at 33ppi, as we usually tow with just the 2 of us I don't see any reason to alter the tyre pressures on the rear.

Hi
Taken offhttp://www.tyresafe.org/tyre-safety/caravan-tyre-safety/advice-and-information/

The correct inflation pressures for your car tyres can be found in the vehicle handbook, inside the fuel filler cap or on a plate located on the driver’s door sill. In the absence of special towing recommendations, the rear tyres of cars should be set at the ‘fully laden’ pressure. Where full load pressure does not differ from that for normal driving , the rear tyre pressures should be increased by 4 to 7 psi (0.3 to 0.5 bar).

Thank You for all replies. The handbook and the door plate both show 33psi normal and maximum load. All previous cars I've had have different pressures back and front and always quoted a towing pressure.I think I will go on Ray's quote above and the put it up a few psi and see how it goes.

Thanks again

We have towed with the tyre pressures at 33psi and its fine.I usually put the rears up to 36 when we go to France as there is a bit more weight in the boot (awning etc) its fine,
Ours is 62 reg KX2.

Why? You're only adding 75kg weight in the back. This is far below the max load of the car.

I take a fairly heavy mobility scooter in there and i thought it would be better weight wise.

If you're not going above the max weight of the car with the nose weight and everything in the boot why bother? You'll only wear the tyres unevenly, and have less of the tyre touching the road surface, hence less grip cornering or braking.

Because I'm a total numpty when it comes to these things. As said earlier, every car I've had previous have had different pressures on the rear for towing and I thought this one would be the same. We out with the van tomorrow and we see how it tows with pressures all the same. i just thought it normal for rear pressures to be higher.

Nope, not normal these days, so cars do some don't. My ASX does not have higher pressures when towing. Frankly its great to have one less thing to fuss about. What happens when you arrive at a campsite, do you reduce the pressure, and then pump up again when you move on. What a faff!

Report back when you return, my bet is on the fact that you'll not notice any difference, or actually the ride will be slightly smoother.

Thanks Fal. It is a faff with the pressures I must admit. Although I don't let the pressures down while we are away I do reduce them on my return home. Hopefully one less chore.
