I have an Ace jubilee statesman, with 175r14c tyres which I have replaced prior to my holiday we spent the month of September in the south of France. I tow with Shogun 3.2 did Elegance,  I noticed straight away that the caravan felt very uneasy on the back of the car, and I was feeling every blast of air as traffic overtook, especially high sided vehs, we pulled over and adjusted the load in the caravan which made things a little better. When I had the new tyres put on the recommended pressure was 65psi which was what I put in, prior to this I always towed with 55psi has anybody experienced this before and can anyone offer advice, I have been caravanning for over 30 years so I am not a novice. Any suggestions gratefully received.

I have never had that much pressure in mine,usually 35 - 40psi and no issue as its only a single axle and light van.Does it have a stabilizer or alko hitch,maybe worth checking them out too Smile

It does have an Alko hitch and stabilizer and were serviced earlier this year, so I know they are alright.

Did you replace with 8ply van tyres or cheaper car tyres? (hopefully not budget car tyres)
the 8ply van tyre has a stronger/stiffer sidewall and does make a stability difference on a big twin axle van. (did on my 26ft Superstorm)
also if your van tyre`s a bit over infalted then it will `bounce`more.

did you have wheels balanced after fitting tyres? Tyre company's don't usually balance caravan wheels unles you ask them to, then they don't like it.

No the wheels were not balanced, will consider that as a possible cause.

Hello

   We have similar size tyres on our Bailey and the plate by the door says 55 PSI it has a max load of around 1300Kg.  I found fitting some alco shock's helped a lot with ours but your van may have them as standard.

Regards Mark

Thanks Mark,

My plate just has the two weights, I got the 65psi of the actual tyres, I guess the only choice is to go back to 55psi and see what difference there is, unless somebody else has any ideas.

Go back to 55psi. 65psi is way too high
Make sure wheel nuts are tight  Laughing  
Worn pads in the alko hitch will cause the van to swing

The 65psi is max load per tyre e.g. 65psi at 1340kg.
It is not a recommended inflation pressure.
If your van was 1340kg on a single axle (2 tyres) the pressure per tyre would be 32.5 psi, from what i remember you treat each axle independantly so twin axle each tyre would be 32.5psi.
If you run at 65psi you will end up just getting a bald patch in the centre and serious overheating on the tyre, as an added bonus when the tyre pops they will hear the noise 5 miles away Wink

Been a long time since i did any of this but it's worth reading up about.

Thanks Gegs your posting makes good sense, the charts are especially helpful, I will adjust the tyre pressures down to the charts recommendation next time I go out, which now will probably next year. I wonder why the tyre manufacturers allow so much confusion when it comes to caravans, there's enough of them on the road.
