TYRE PRESSURES

[Bertyboy]

Hi All,

I have a Pilote 715 Explorateur on an Alko chassis uprated to 3850 kg can anyone tell me what my tyre pressures should be please.?

What tyres have you got and what axle loads?

I use this chart

Hi Martin

Tyres are Michelin 225/65 R16 xc
Axle 1) 1870 kg
Axle 2) 2100 kg

Cheers Bertyboy

I'm sure you can get chart online for your wheel size

So I take it you have been on a weighbridge and had each axle individually weighed?

By "axle weights" I meant actual weight via a weigh bridge as the weights quoted would put you overweight so I assume these are maximum plated weights.

Also the tyre load rating is important in the tyre pressure calculation.

Armed with all the above information I would then use the chart as above OK it's from Continental but as long as the size and load rating are the same I would use this for Michelin as well, I believe the link below is the same information as @GeoffChausson posted, scroll to page 80 something for your size.



I will add this is just my opinion and not a professional view

As @funflair says you need the actual axle loading.

You can then email Michelin with this info and tyre size etc. and they will advise you. They will provide you with a recommendation for the front but normally they will tell you that rear should be 80 psi.

There are loads of threads on this forum if you search tyre pressures.

At a guess, I would say 80psi rear (Michelin always advise this) and 68 fronts...

Get the ven weighed fully loaded and send an e-mail to Michelin they will confirm.

I have a 2013 Pilote Reference P716 which I believe is similar to yours but mine is a maximum of 3500kg.

You need to know the front and rear axle weights (around £5 to use a local weighbridge) and the size and type of tyres you have before adjusting your tyre pressures.

Any guesswork will mean your tyres probably won't last as long and may wear unevenly.

With the tyres I have fitted - Continental (225/70 R 15C 112/110) - on my Pilote on a Ducato base and with front axle 1560kg and rear axle 1940kg, confirmed fully laden by a weighbridge, the recommended pressures are 47psi (3.2 bar) front and 61psi (4.2 bar) rear.

You may need slightly higher pressures at 3850kg but not a significant increase I would have thought.

Michelin have always recommended the maximum pressure in their tyres, and many of you will continue to take their advice, but those who have actually weighed their vehicles and reduced pressures will know what a big difference to ride and comfort is achieved.

I'm never sure why Motorhomes are run at the tyres maximum, usually 80psi, which gives a harsh ride and on many roads could dislodge your false teeth and certainly rattle the chassis with the hard tyres and no 'give'.

Everyone has an opinion on tyre pressures but my Pilote has run well with minimal tyre wear over 30.000 miles and there's no reason why yours shouldn't do the same with similar pressures.

Hope this helps.
