Just had 4 new Michelin tyres fitted

[Nirvanauk]

They were 8 years old so not bad but no sign of wear or cracking. They are Agilis camper tyres and the four cost £645 from a Michelin dealer.
I asked what the tyre pressures should be and he didn't know but told me to consult my base vehicle handbook ( which is a Renault Master) and that says 4.4 bar and 3.8 bar but doesn't that depend on the type of tyre as opposed to the type of vehicle? Any advice please?
Thanks.

To give the default MHF answer...

Go to a weighbridge, weigh the front and rear axles, give the axle weights to Michelin via their website. They will say put 5.5 bar in the rear and the front will be based on the axle weight.

Then come back and say "These tyres give a hard ride. What tyre pressures do funsters have on theirs?"

We give suggestions varying from 3 bar to 4.5 bar.

In the end you'll find what works for you.

If you email Michelin with your actual axle weights they will tell you the suggested pressures.
Cheers
Bernie

80 psi, I've never heard Michelin tell anyone any different.

 

[Sidney]

and of course I forgot to say...

I hope the tyre fitter used high pressure (steel) valves

Tyre pressure for all Michelin Camping tyres is 80 psi regardles of size
Brian & Jo

 

[mentaliss]

This Calculation is considered to be the most effective way to set your tyre pressure's:
The load index ( 112) means that at max pressure the tyre can support a load of 1120 or 2240kg per axle

Example:
Max pressure 80psi divide by max load 2240 = 0.357 x actual load 1950 = 69.6psi

the above calculation would suggest that the rear axle tyre pressure's should be around 70psi

Sorry, what your quoting is the max pressure that the 112 index tyre will inflate to not the pressure it may need to support the load

 

[DonA4000]

In my motorhome hand book it says (rear) 5.5 bar (80 psi) but on the side wall of the tyre (continental van/camper) says maximum 69 psi, so what you suppose to do then?

 

[Jim]

This Calculation is considered to be the most effective way to set your tyre pressure's:

Except Michelin for some reason don't do those calculations. No matter what combination of gross or axle weights you supply them. They always come back with 80psi.

Michelin will only give a weight related pressure for the fronts, their policy for some years now is to quote the max 80 psi on the rear as Jim said. They believe that the majority of vans are overloaded at some point so will not give on that.

ring michelin technical,they will clarify it

[TheDogMan]

I had 6 fitted( double wheel at back) 2t front axle 3.2t rear axle, I was adviced by fiiter to go 70 - 75 psi, oh and yes mitchelin will say 80 as that the tyre max marked on the side

 

[Sidney]

80 psi, I've never heard Michelin tell anyone any different.

Yes 5.5bar = 80 psi ...but they do give lower figures for the front tyres (based on the axle weight)

 

[Ber090]

Jim, Sydney is correct. Michelin will give various pressures for front bot stick to 80 for rears.

Oh Lord! I get sooo confused when this thread appears occasionally. I hope 60/65psi (front/rear) is enough for my 7.2m van. Can't be arsed with weighing it, sounds so much agg'

Wish the dealerships or whoever would just provide a rough guide, assuming a given load. They do this with cars.....On the door pillar you get a picture of the number of occupants next to the tyre size fitted, then the required tyre pressure. Simples!

Yeah, I know what you're honna say; dealerships wouldn't know how much tut you put in your van. Some folk travel light, whilst others carry everything from Avalanche poles to a gas rattle! Having said that, couldn't they come up with an equation based on max payload?

When white van man buys a Tranny, no one asks him to go to a weighbridge with all his tools in it, he just looks at the door pillar.

Is there a more simple rule of thumb? Tyres hot - pressure too low...... Dental fillings knocked out, pressure too high

 

[ASel]

Iveco in their manual provide tyre pressures for different axle loadings, do other manufacturers not give this info?

 

[Brian and Jo]

Jim, Sydney is correct. Michelin will give various pressures for front bot stick to 80 for rears.

in the main michelin say 80psi but very occaisionally they will say 69psi front but in the main its 80psi regardless whenever we have a motorhome in for tyres i will always do a bit of spade work before it arrives as to tyre pressures,wheel nut torque settings etc.cos it is a minefield.

[Techno]

They gave 65 psi for my fronts for previous owner with 1820kg and at that time 2008 they gave 60 for the rear. 116 load index
I have altered these myself due to increased loadings and now have 67 front 80 rear.

These so far all increase by 8 psi when driving (Tyrepal)

that is 64psi and 55psi,way to low for Michelin Camping tyres.

Bloody hell £645 for 4 I'm seriously considering 6 new ones for my van in the next few weeks.
Read somewhere the Vredistein Comtrac is as good as the Michelin but nearly £50 cheaper. Having said that my Michelins have been amazing for mileage and grip and especially good in the snow and on grass. Get what you pay for I suppose.

 

[Techno]

Michelin are VERY cheap just now but that is no comfort to the OP who has paid way over what is available for Agilis camping.

Shame mine are 225x65x16 my tyres price fitted £144each
continental vanco camper £127 fitted. I also need 4 which is best to go for.

and all this before you go anywhere.

Always a good idea when you stop for a break to walk round the van as soon as you stop and feel the tyre surface, they should be warm to the touch. If hot they are under inflated or have problems within the tyre, if cold they may be a bit over inflated. Its an old truckers trick as it can be difficult to see under inflation on dual wheels.

The above sounds high to me. I have a similar configuration and was advised the same but this disagrees with what the chassis manufacturer recommends which is what I use after have checked front and rear axle weights on a weighbridge. I actually have commercial van tyres not campers and I use 65 psi on the rear twins and 60psi on the front.

Just had four 225/70 R 15 CP 112 tyres delivered from Camskill. They cost me £367.76 delivered. Presumably this is the Euro effect!
Fitted them myself, inflated to 5.0 bar, the van rode as if on a magic carpet, none of that "crashing" through potholes. Yes, I will be adjusting the pressures before travelling. Out of interest the new tyres felt a lot softer than I had imagined they would after hearing all about reinforced sidewalls. The tyres I removed were the original (08) Continental Vancos on the rear and Michelins on the front (new when we bought the van in 2011) which I was pleased to have worn out! The old Vancos were very cracked in the side walls but seemed to still have all their tread and seemed to be made of concrete whilst the Michelins were as soft as the new tyres. Anyone recommend rotation of tyres (front to back) as I seemed to have only got 20K out of the Michelins although I do like to use all the (160) horses for accelerating.
Cheers, Steve

Can't beat tyrepal anything unusual is immediately reported. All my tyres rise by the same 8 to 10 psi in use and temperature is available although I don't use it. Any significant change in normal parameters in any one tyre is a signal to pull over while the tyre can be salvaged. Worth every penny
