StarSpirit tyre pressures Forums

Cherekee

It would seem that the StarSpirit Boxer 2004/5 vintage is a popular motorhome. What is the concensus of the best tyre pressures please? We have 215/70 R15 Camping tyres fitted.

Also any members going to the Autocruise open w/e September 30th at the factory?

Hi cherekee

Dont know if this helps as I am on a Ducato 15 base.

"Thank you for your recent e-mail.

The tyre size quoted is able to run at the following axle loads/pressures, when
fitted to a 'single fitment' axle (one tyre only each end of axle):

215/70 R 15CP 109Q 'XC Camping'

Axle weight Pressure
(Kgs) (psi)

Quoted wts: 1750 54 Front
Quoted wts: 1850 57 Rear

+10% front axle:
Should you wish to help the front axle tyres cope more easily with the weight
transfer forward under braking, we suggest that you may increase the front tyre
pressure by 10% above any final calculated 'static' value, providing the maximum
pressure (80 psi) is not exceeded.

Final recommended pressures:

Front: 59 psi
Rear: 57 psi

* Note: The above pressure values are only recommended for the axle weights
stated above.
Have you verified that each axle weight for your vehicle is actually being run
at or below these quoted weights, by visiting a local weighbridge?

Weighbridge:
We suggest that individual axle weights from weighscale readings are used, in
order to calculate pressure recommendations for each quoted load conditions.
These would be preferred, due to readings being taken in the actual vehicle
'running' condition - that is to say, with all water/fuel/baggage & passengers
etc. onboard - and may result in better comfort if the vehicle is running way
below maximum capacity.

The results of surveys show that too many motorhome users run their vehicle
overladen (read illegal), with little regard for axle weights and subsequent
tyre related problems.

The overall industry, therefore, tries to build-in a safety factor by fitting
specific, strong 'motorhome' tyres, inflated to high pressure, in order to
prevent the drastic consequences of overloading &/or under-inflating the tyres.

The drawback of this safety factor, at the corresponding high pressure, is an
extremely hard ride. The contents of the motorhome may rattle, but the tyres
will cope nicely.

Once again thank you for your interest in Michelin

Yours sincerely
Michelin Tyre Public Limited Company"

hi all,
the subject of tyre pressure has been greatly disscued with a variety of responces- it really depends on your van load check the local weigh bridge then adjust .we run at 3500kg and have rear 75psi and front 65psi when half full 3200kg drop rear to 70psi and front to 60psi. be carefull if underinflated the tyres air get too hot and explodes Embarassed

number one reason for a blow out. if ride very hard deflate a little at a time but check for bulgs at base of tyre.
I drive hgv's for a living and always suprised not when peole say they had a blow out and i ask what load what tyre pressure and they say "I don't know" Twisted Evil

ignorance is bliss eh!!!

Hi Cherekee.
I have a 05 Starspirit on a Peugeot Boxer base and, like you , am also mystified on the correct tyre pressures. Inside the driver side cab door the tyre pressures for both front and rear tyres is given as 79.5 psi or 5.5bars. I have spoken to other Starspirit owners and they are equally vague. I am going to the weekend 29/30 Aug and Sun 1Sep and hope to get a definitive answer from Autocruise. I will look out for you.

My Starspirit was delivered new with 70psi all round and I have kept to that. Seems ok to me but then I rarely drive over 60mph. As an aside I get about 29/30 mpg and have from new (now 10k miles). Both Autocruise, last years open w/e, and Marquis, suppliers, were very cagey about quoting pressures.

We are off on a six week round Britain trip tomorrow, Monday, so won't be logging on for a while. The van is loaded and ready to go in the morning. Hurrah.

Thank you all for your responses so far. I intend to take the van to the weighbridge prior to our next trip mid September when loaded and send email to Michelin Tyres for a response. I run at the moment at 75 all round but ride a bit hard. Milage at 6000 gives just under 25mpg so still running in. I have been following the thread's on tyre pressures. My open day at Autocruise is September 30-1 October. Are they running more then one?

Hi Cherekee.
You are right about the dates. Just me having a senior moment!!!!! Embarassed

arty23

I have a starblazerXL and e mailed autocruise for their suggested pressures and received an immediate reply by John Seale their tecnical manager 47psi front and 55psi rear.

Cherekee

Further to my first question this is the reply I have just recieved from AutoCruise. Hope this helps StarSpirit owners.

Thanks Arty23 Why didnt I think of that!!!

Hi Alan

Michelin have provided us with a tyre pressure listing and for your vehicle they give front 46 psi and rear 50 psi.
