2017 Broadway Tyre Pressures??

Hi,
I wonder if someone would kindly advise me what air pressure to inflate my Broadway tyres. We are off to France next week and I noticed one tyre looked a little low.
Apologies if this is not posted in the correct place but this is only my first or second post.
Many thanks in advance.
John.

The correct pressure will depend upon various factors. Indeed, there are copious threads on the Forum about this question. Even for just one model e.g a Broadway 2017 the pressures will vary as between different makes of tyre (Michelin usually being greater than, say, Continental).

Tyre manufacturers publish a table. For each size of tyre (e.g. in my case Continental VancoCamper tyres, size 215/70R15 CP 109R) the table shows what pressure to use for front and rear. But that is determined by looking at the axle weights.

Thus, to do the job properly, you should get the vehicle weighed in full holiday trim, obtaining the front and rear axle weights. [Incidentally, that'll also let you know whether you're running safely at below the maximum permitted mass per axle and overall.]

With those axle weights for your van with your unique payload you can then see the correct pressure for your make and size of tyre.

That's the correct method.  You need only do this once. With luck, other Broadway users will tell you what they use for their tyres - but your circumstances are likely to be marginally different. At least that'll give you a guide.

Can I add a little caveat to the above, if you (like what we do) have the Peugeot tyre pressure warning system, it will most likely be set for the pressures set out on the label on your door pillar. Reducing the tyre pressure without getting these reset may cause you to get a warning message on your dash. As Cymro says, there are many threads on the subject and it would be worth your while doing a search for them.

I've edited your title so it's more meaningful. That "Description" line doesn't show in the format that most members use to view the forum. (It's a pain in the backside, but we're stuck with it!!)

Tony's caveat is well worth noting.

Our Peugeot main dealer recommended 65 front and 70 rear as a good compromise that is unlikely to trigger the TPMS.

Your van is unlikely to be much different to ours, and bearing in mind that a lot of members appear to run at 55 front and 60 rear (or even lower) with no problems, you will have a good safety margin with 65/70.

Only my opinion of course!

A postscript: Askit and Gromit are right to mention the likelihood that if you elect to run on pressures which are significantly lower than those shown on the (one-size-fits-all) plate on the door pillar, the TPMS may activate. That, I'm afraid, will necessitate a trip to Peugeot to reset the TPMS to accommodate your preferred pressures.

Only then will you achieve Nirvana: correct pressures for your van, with no TPMS sounding because it thinks you should run at bone-shakingly higher pressures.

It's a tortuous process to get there!  I run at 55:75.

Cymro

Not wishing to alarm Cymro and/or others, but the maximum inflation pressure (cold) on our Vanco Camper tyres is stated as 69psi.

No doubt there's a healthy safety margin, but I wouldn't want to run them at 79.5psi as printed on the door pillar.

Those members who recommend sticking to the Peugeot figures should perhaps examine their tyres and reconsider??

Wow, what an amazing response! This really is a most helpful group and I can't thank you guy's enough for taking the time and trouble to advise.
I had looked around the door frame and pillars but could not see the usual plate on my vehicle but thanks to the suggestions, I think I will aim for something in the region of 60 / 65 front and 65 / 70 rear. I realise I could go to the length of weighing and consulting Tyres / Peugeot / Autosleepers but we are going to Brittany on Tuesday and I have a busy weekend.
Many thanks again, I am really impressed with this group.
Best regards,
John.

Gromit is wise to draw attention to the reference to 69psi written on the sidewall of that particilar tyre. It says that the maximum load for a single wheel at 69psi is 1,030kg. But that is in the context of loads, not pressures.

However, the elsewhere on the tyre, where it deals with maximum pressures, the text reads: "Tire [sic] failure due to underinflation / overloading [not "overinflation"] -  follow vehicle owner's manual or tire placard in vehicle."    "Due to special service conditions of motor caravans it is permitted to increase tire inflation pressure.  Permitted Maximum Inflation pressure 5.5 bar" (which is almost 80psi).

The only way to reconcile those sentences is (a) you must not exceed an axle load of 1030kg when the pressure is 69psi; (b) you may - because you're a motorhome, increase the inflation pressure; (c) but you must not exceed 5.5 bar.

But (a) the tyre placard placed by Peugeot on the sidewall recommends 5.5 bar plus/ minus 0.05bar [80psi]; and
(b) Coninental's chart for that tyre suggests a pressure of up to 5.5 bar where the axle load (and vehicles permitted overall mass) warrants such a high pressure.

The warning on the sidewall is, I believe, an American requirement. That may explain the strange mixing of units - psi and bar, as well as the spelling. That's not to say it can be ignored in a cavalier way, but - trying to reconcile that warning with the other recommendations - I see little risk in running at 5.5 bar [80psi].  Plenty of defendants there for my executors!

But my dentist is happier if I retain my teeth and travel at a lower pressure. So, for my unique loads on my tyres and in my circumstances, I compromise at about 55:75.  It works, and is below the permitted maxima.

Apparently the maximum pressure is only applicable to North America, dont ask me why, maybe they have different pressures than us or maybe in the UK we just like to fly by the seat of our pants.

John - i have a 2012 broadway 4 berth and was thoroughly fed up with trying to ascertain appropriate tyre pressures for my continental  vanco tyres from the forum and AS and emailed continental with weighbridge figures on a van with driver/passenger and average fluid/interior weights. They were extremely helpful and quoted me 47 psi front and 72 psi rear. The van runs comfortably on these figures but I firmly believe that the average weights of a particular model would fall into a narrow band and I see no reason why AS cannot recommend a range of pressures for their individual models. Would you spend £50k on a new jaguar car only to be told that you must approach the tyre manufacturer for the correct pressure ? I think not. All cars specify pressures for different loads. Why can't AS do the same ? You quote 60/65 psi for front which seems far too high to me. Hope this is helpful

If you have all the information on weights, the Continental Tyre manual, (copy in Factsheets section) will give you appropriate pressures for various weight combinations.

I read that max  pressure is for American market only , the stated pressure for my nuevo. Is 5.5 bar .R ...5..0 bar  F ..so that is what I use I was also told by auto sleeper main dealer to use that pressure ,these pressure are auto sleeper ,not Peugeot .Peugeot vans don't use campervan tyre's .

Indeed so. But sometimes they conflict. And in those circumstances many of us believe that it's better to adhere to the specialist recommendation of the tyre manufacturer, according to its published lists of correct pressures for its tyres for the measured axle weights for the tyre type and size involved, rather than relying on the general recommendation of the vehicle manufacturer (who must err on the safe extreme because the manufacturer has no way of knowing the purpose to which the base vehicle will be put, let alone which tyres will be fitted, what weights will be carried, what weight distribution there will be .. and so on.)

Nevertheless, there's merit in the point made above by Sunbeampizza: "....but I firmly believe that the average weights of a particular model would fall into a narrow band and I see no reason why AS cannot recommend a range of pressures for their individual models. Would you spend £50k on a new jaguar car only to be told that you must approach the tyre manufacturer for the correct pressure ? I think not. All cars specify pressures for different loads. Why can't AS do the same ? "

I suspect that the fear of litigation has an influence on AS's stance (and those of other manufacturers).

As has been repeatedly written on the Forum (a) it's easy to become over-concerned about correct pressures - when it's perhaps more important to check the pressures frequently; (b) whilst the optimum way to work out what precise pressures should be adopted is by use of axle weights and tyre manufacturer's charts, one won't go far wrong by adopting the average pressures reported on the Forum for various models - which often means considerably lower pressures in the front, and slightly lower in the rear.

Cymro

Reading this thread has thrown up more questions than answers, variations from 47psi to 72psi for instance for front tyre pressure is an amazing range. 
What are the police guidelines on inflation, plus or minus 5% of manufactures recommendations or thereabouts.
This advice falls well out of that range.
My tyres were nitrogen filled by Selecta 3 years ago when new to 60psi all round. I've never touched them since, but reading this has prompted me to check them, still 60psi, so I'm leaving well alone.
Al.

Cymro, your third paragraph speaks volumes. What would be nice, and helpful, would be for them to admit that is the case so we could move the discussion on. My TPMS failed on delivery of the vehicle because of two faulty sensors, which were replaced under warranty. I then got involved in a pointless exchange of emails with AS on the subject of tyre pressures (as I guess many had before me and probably many more since) that resulted in a standard reply, pointing me to the base manufacturers recommended figures.

I get it, the legal responsibility bit. Meanwhile experts (if we can call them that) from the big MH magazines and those who manufacture the tyres give different advice based, not just on comfort, but safety. In between  those, we are left to toss a coin about who’s advice to follow.

I rather agree with a lot of the comments here, I wouldn't consider there is a huge margin between the loaded weight or half loaded weight on any particular model, when compared to the overall weight of the vehicle. I guess we all drive with something between half empty tanks and full ones. I am certainly not going to drive the vehicle completely empty. I also cannot understand why AS can't give a ball park figure unless different tyres would preclude this. If that should be the case it is amazing that tyre manufacturers can't conform to a common standard for tyres that are designed to do the same job.
Anyway, thank you all for taking the time and trouble to advise, I am now going to toss a coin before checking pressures!!
John.

I can only speak for the Continental Vanco tyres which are fitted to my Broadway (2016) but it’s not that difficult if you get the manufacturer’s advice. Unfortunately most dealers and the AS workshop themselves are rather in the dark about the whole subject. It’s mostly been covered above but it is absolutely essential to weigh the vehicle fully loaded and get both axle weights. You only ever need to do this once really. Then you simply apply the pressures in the Continental data sheets for your axle weights. Unfortunately, there are things which will send you off on the wrong track. Firstly the maximum pressure stated on the tyre which has been mentioned. This is solely to do with the USA market and should be ignored. Secondly, the weights on the inside of the cab door frame. These should be ignored because they relate to the Peugeot base vehicle and not the AS conversion. Thirdly, when you more than likely reduce the tyre pressures (particularly on the front axle) you will more than likely trigger the low pressure dashboard alarm that is set around 5 bar I think. So, you will just have to ignore it or inflate to a higher pressure which is what I do.

I have yet to hear of anybody managing to get Peugeot to reset the pressure levels but would be interested to know if it’s been done.

I'm pretty sure Cymro has had his reset by Peugeot although they were reluctant to do it

I have indeed. Well remembered, Paul!

I reported it all in a thread on the Forum in 2015 (which I can't quickly locate, I'm afraid).

Having done points 1 & 2 on BornAgain's list, and having thereby worked out that I wanted to run at 53:73psi, when I deflated the fronts from whatever high pressure they were at, of course the TPMS was activated.  And TPMS can only be reset by a dealer on a Peugeot. So off I went, and insisted that they set the TMPS to trigger when the fronts drop to 50 and the rears to about 65.

The invoice reads" Carried out customer request for TPMS calibration to be dropped to 3.5 bar in the front and 4.75 bar in the rear. Advised customer that this is lower than the Peugeot recommended [sic] of 5.0 bar front and 5.5 bar in the rear. Carried out operation, reset tyre pressure and road tested."  £39 to you, my boy.

And every time I take it for service, they don't touch the TPMS - but inflate the tyres to 80!

I found the thread....

I doff my cap to you, Paul!  I'd had a go at trying to find that thread, and failed. Thank you. I see that my post of 27 July 2015 confirms what I remember. I hope that it's of help to BornAgain and others who want to have their TPMS recalibrated to more reasonable pressures.

Cymro

Thanks for that. I am running near 2000kg maximum on rear so the pressures are quite high but I could run the fronts at much lower pressure. Anybody know whether reducing the front pressures only would have much affect on ride quality?

When I bought my Broadway Marquis told me to use 65 all round which gave an aweful ride. I contacted Continental with weighbridge results and they advised 47 front and 72 rear and the ride is transformed !
