tyre upgrades and pressures

Sorry but this story could be taken a bit out of context!  I have had occasion to ask a manufacturer what tyre pressure was needed for a particular type of caravan and the response was 61psi. 

Some years ago I changed tyres on the van I had at that time and was told that 'van' tyres were appropriate and 50 psi was the recommended pressure.

I now have a 2012 Challenger Sport and that has tyres rated at 62 psi.  I would say that the van tows beautifully but perhaps there is a little bounce there but I put that down to the addition of shock absorbers on this model.

So anyone taking what has been said in one particular case that pressures recommended by an apparent expert are incorrect could be making a bad mistake.

Perhaps we could ask the 'experts' to give us some firm advice?

This is no critism of the OP but this is such an important subject that I felt that something should be said.

I have since checked on my Swift Challenger Sport and  a pressure of 62psi is actually stamped on the plate attached to the van giving the various weights etc.

sorry gentle englishman but are you saying i should take my pressures back up over fifty psi or that each van has a specific pressure no matter what tyres it has -- on the old tyres my psi is stamped on the van plate is at 33 but with the new 6 ply tyres the mechanis pushed them up to 50 - after checking with the technical dept they advised me to reduce this to 36 psi -- my van ran on the normal 4 ply tyres when purchased new and the mechanic advised me to upgrade as a lot of people are now doing so for various reasons -- also my caravan is a twin axle which is probably why the pressures are lower than your caravan which i think is a single axle hope this explanation puts right any confusion i have caused

Thank you Spit3030 for your kind words for the information Technical gave you. We do ask members exactly what tyres are on the particular caravan, this enables correct tyre pressures are recommended for the MTPLM. The tyre pressure tables Technical use come from BTMA (British Tyre Manufacturers Association). If you are in any doubt of what the pressure should be for your caravan, please call Technical and we can advise you, we just need the exact tyre size e.g 175 R13 97N and what make of caravan you have.

On our previous 'van, I dropped the tyre pressure three psi, and it towed a lot better than when new. We had this 'van for 14 years, and never had any problems. Our new 'van has twin axels, and I run at the pressure as supplied new. maybe more rubber on the road makes the differance.

thank you staff  member this is what i had done and have to say that after quite a few trips out now the van tows spot on
