stanwilson100yahoo. Posted February 7, 2016 Share Posted February 7, 2016 I know this is a subject that crops up in various magazine articals from time to time there would seem to be differing opinions as to what pressure front and rear tyres should be set mainly due to comfort ? my problem is I have a 2015 peugeot boxer euro 5 cab front pressure 60 psi and 80 psi to rear quite a hard ride , however i have taken the van back to the peugeot dealer as the tyre pressure warning system (on the dash)indicates firstly a low pressure flashing light followed by the light staying on indicating system not working the dealer says it was because the pressures are not correct they were as close as I could get them at the time although he will plug the vehicle into a diagnostic machine for £70. this happens most often on a wet cold day, not on a clear bright dry day as when i visited the dealer anyone have a thought on this? secondly 80 in the back is really hard but if the pressures are not as advised the light will stay on full time looking for suggestions .

Brian Kirby Posted February 7, 2016 Share Posted February 7, 2016 From your description of the way the system is working, it seems it may be faulty. On a 2015 van, which should still be under warranty, I see no reason for the dealer to charge you to check that it is working properly. If the tyres are under pressure when he checks them, and that is the problem, I can see no reason why he should not charge you. Trying to get around the tyre pressure monitoring system seems to be a bit of a problem. It seems that once set by the factory it cannot easily be adjusted to lower pressures, if at all. You may have to out up with flashing lights, or just accept the standard pressures. Link to comment Share on other sites More sharing options...
bigparkie Posted February 7, 2016 Share Posted February 7, 2016 Not sure on Peugeot but on ford you can set the pressure then scroll through cluster menus and hold reset button.the Manuel should clarify but I think u have probably got fault.

Derek Uzzell Posted February 8, 2016 Share Posted February 8, 2016 stanwilson100@yahoo. - 2016-02-07 4:41 PM ...I have a 2015 peugeot boxer euro 5 cab... Is this a Bailey-made motorhome by any chance? If so (or even if not) it would be worth you reading the forum discussions listed here http://forums.outandaboutlive.co.uk/forums/search/query.asp?action=search&searchforumid=all&keywords=tpms&author=derek+uzzell&days=365&Submit=Search Link to comment Share on other sites More sharing options...
Tracker Posted February 8, 2016 Share Posted February 8, 2016 My car has a TPMS and it is so sensitive that it lights up on a cold tyre and goes out when the tyre warms up and increases it's own pressure - easily cured by adding a wee bit of air. It also has the capacity to be reset by the user to any any pressure within a pre defined range and I wonder if the Peugeot system too has that facility particularly as the Sevel chassis cab is designed for various bodies, tasks, payloads and overall weights?

Derek Uzzell Posted February 8, 2016 Share Posted February 8, 2016 Tracker I hesitate to say this, but if you take the trouble to read through the earlier forum threads that I provided links to (and also read the the threads on other forums that those earlier Out&AboutLive discussions contain links to) you will find a) That the TPMS fitted to Peugeot Boxers (and to Fiat Ducatos) has no user control over the ex-factory pressure settings, nor can the TPMS be user-disabled through any sort of dashboard-menu/button-pressing facility. b) That it is possible to have the pressure settings of a Peugeot Boxer’s TPMS modified by a Peugeot agent that has the necessary equipment and expertise. It should be anticipated that this task will attract a charge. (Richard (‘bigparlie’) mentions Ford in his earlier posting. In the case of the latest Ford Transit it is possible to user-reset the TPMS via a menu system/reset button, but this capability is not offered on Boxers/Ducatos/Relays.)

Tracker Posted February 8, 2016 Share Posted February 8, 2016 Thanks Derek but as it does not, and is unlikely ever to, affect me directly I did feel the need to burrow back through the history, and I can only hope those that are affected are duly graetful for your dilligance.

Tyre pressures, if they are to be altered from the recommended pressures, should only be altered to suit load, not to suit comfort. That is just to say, reducing pressures until the ride is deemed comfortable might well result in dangerous under inflation. However, once the pressures are optimised for actual load, you can anticipate some improvement in ride comfort, and possibly also in directional stability and general handling. It must be remembered that manufacturers can never know how a vehicle might be loaded by its owner, so set their recommended pressures to suit the maximum permissible load on each axle. Technically (unless a van has been re-plated), it is not possible to simultaneously load both axles to their maxima, without exceeding the maximum permissible weight of the van. There is thus a bit of overkill in their recommended tyre pressures, but it is done to provide flexibility in how the load may be distributed. It must also be remembered that running tyres below the optimum pressure for axle load is potentially dangerous. Under inflated tyres generate excess heat, which can result of blow-outs. Over inflation, OTOH, merely results in slightly twitchy handling and a harsh ride, possibly in conjunction with some minor loss of adhesion. But, within the pressure range the tyres are designed to accommodate, over inflating presents no safety risk. To get the correct pressures for the weight of your van you will need to weigh it on a weighbridge, getting the actual load on each axle as well as the total weight of the van. For this process to be useful, the van must be weighed in its fully laden state. That is to say, in the heaviest condition in which you are likely to run it. So, full water tank, full fuel tank, full gas cylinder/s, all clothing, footwear, bedding, food, drinks, books, games, bikes, camping gear, and driver and all passengers on board, including pets, if any. (Apologies for labouring this, but I'm somewhat tired of stressing "fully laden" to find an enquirer responds that they did as I suggested, though with the fuel tank half full and the water tank about three quarters full!) Once you have the axle weights, you can safely reduce the tyre pressures to those recommended by their manufacturer for those loads. If your tyres are Michelin I suspect they will not recommend reducing the rear pressures, but will suggest lower pressures for the front tyres. If by Continental, you should be able to download Continental's Technical Databook from their website, and this will give you the correct pressures to use. You must ensure you select the exact tyres fitted to your van in doing this. It is unlikely you will find an exact match for your actual axle loads, so use the next higher pressures, and never the next lower. An alternative source is a document published by Tyresafe.org that gives a lot of generally useful information about tyres as well as recommended pressures for load. This is downloadable from their website, though it is somewhat "hidden". Look under Tyre Safety, then go to the panel entitled "Motorhome tyres and your safety" and click on "View more". The document will then download. It lacks some of the detail of the Continental Databook, in that not all sizes and variants of tyres are listed. However, the most popular sizes are there. On the table for "Specialised motorhome (CP) tyres" (what I would expect to be fitted to your van), you will find a misleading footnote regarding the single rear fitment. Disregard this, as the pressures are correct for rear tyres whether driven or not. Hope this helps. Link to comment Share on other sites More sharing options...
