Tyre Pressures

Having moved across from caravans to a mho, which we have only had for a couple of weeks, and done a couple of day trips, our initial impressions are, " its a real boneshaker'. Like riding on solid tyres.

I know our roads are not kept in the best of condition, but even so, this is an uncomfortable ride.

The mho is a 2015 Bessacarr Hi-Style 412, based on 2.3L FIat Ducato, and has done just over 6000 miles, so not a tired old workhorse.

The Fiat handbook say 80psi all round, which what the tyres are inflated to.

The tyres are Continental 225/75 R16 CP 116R , and on the tyre wall it says 69psi, which I assume in the maximum.

Having had a browse around some of the mho forums, an overly hard ride seems to be a commom complaint, when running the tyres at 80psi, and I have now experienced it.

It seems that some owners run at around 65psi, and enjoy a much more comfortable ride.

What do you guys do?

I'm inclined to drop them back to the tyre manufacture's specified limit (69psi) or just below.

Kev - I'm no expert but I believe the lowest pressure you can run the tyres, before a light warns you, is set and recorded in the ECU.

If Peugeot won't, or can't, reset to allow you to lower the pressures could I suggest you contact an ECU repair business and ask them if it is possible to help you by resetting the ECU.

Try asking ECU Testing of Heanor (Derbyshire) 01773 535638 if they can help with advice – I had to use them when my ECU started malfunctioning and they were very helpful in repairing it.

I don't know if the problem you have can be sorted out but for the price of a phone call it may be worth a punt to preserve your gnashers.

Also ask the same question on the free forums of the 'Out&Aboutlive' forums - https://www.outandaboutlive.co.uk/ - the forums of MMM who have very good people with much more technical know-how than me,

Hope this helps.

We have an 18 plate Peugeot based vehicle, same issue with tyre pressures, we have weighed and reduced pressures accordingly but have a constant yellow warning on the dashboard. Phoned a couple of Peugeot dealers but they say they can’t do anything, I have read that they can but won’t!!

so I have a high tec safety monitoring system which I can’t use unless I choose to rattle the hell out of the mo and my false teeth

Totally useless system if not adjustable and settable by the owner of the vehicle.

 I would get the senders removed, and replace the system with a settableTyresafe system, which works and doesnt ' cry wolf'  by posting an error which doesnt exist.

Thanks K&M will get it sorted at some stage.

The problem with removing the senders is I’m not sure if it would be an mot fail as TPMS is now a legal requirement to have on all new vehicles. That would not solve the problem of having a yellow awning on the dash and it may even be red without senders.

The whole system is a cock up, with a vehicle like a mh the weights can differ so much but the manufacturers set them to the highest setting and sod the end user. We are not like hgv vehicles running on air we are Motorhomes running on springs and it’s uncomfortable setting to the stupid recommendations
