Tyre Pressures - Autosleeper Nuevo ES

[Petros]

I have had conflicting views on what the tyre pressures should be on the above, one recommendation is to use the base vehicles pressures (Peugeot Boxer 79.5 psi alround) but autosleepers themselves say they should be 66 psi front and 70 psi rear. Any viewsoh:

The base vehicle pressures wont be any good will they. Use the mh manufacturers pressures.

i have the same quandry..... Fiat say 5bar front 5.5 rear ( because the MH is equivelant to a highly laden base vwhicle and those are the recommended pressures...
however....
on the walls of the conti camper tyres is 69psi.....

i have also been given conflicting info.. Fiat recommend in writting on their web site for MH 5 / 5.5bar also I ahve been told that the marking of 69psi is for the US market only???

curently my pressures are 68psi ( checked the day the van was dleived new ) and drives a dream. so until i get better advice 68psi it is for me.

only worry is.. if you have an accident and as part of a vehicle investigation into cause the tyre pressures are checked wher do we stand??oh:

the most accurate and reliable way is a trip to a weighbridge...loaded as for travelling.

you only need do it once if you dont change the load considerably.

get both individual axle weights and Email your tyre manufacturers who should then provide you with their recommended pressures... they made the tyres, they know best. :thumb:

tell them its a motorhome and they will need the size, load rating and, maybe, speed rating...and the axle weights

If I understand - your van is fitted with Continental tyres. The company is very good at advising on the correct pressures. Just get your vehicle weighed and email Continental with the weight on the front axle and rear axle - make sure you include the tyre details and size, and they will email back the pressures. Print it out and keep it with you. You then have a written record if ever you need it at a later date (assuming you don't alter the weight of the van too much).

The base vehicle manufacturers recommended pressures tend to be way too high in my experience, which then give a terrible ride.

There was a similar thread in Match last year. I contacted Goodyear, manufacturer of the tyres on our (then) van and was given this advice:

With the load index being used then the pressure quoted in writing by the vehicle manufacturer will carry the weight of the vehicle.

Pressures for tyres are advised by the vehicle manufacturer rather than the tyre manufacturer.

Many vehicle designers will come up with totally different pressures to suit their vehicles and their desired handling characteristic.

There will have been a great deal of testing to come up to these conclusions. The pressures in tyres act as part of the vehicles suspension design therefore contributing to handling, stability, ride etc.

Contrary to popular belief pressures are not only advised based on the weight of the vehicle.
