I have a new to us AutoSleeper Windrush 2012 van conversion on a Boxer base, and I am having problems with trying to get the right pressure for the van
After searching this and other forums, the advice on old threads seemed to be weigh vehicle and contact tyre maker.
I have done this (trying to do the right thing) but had no joy and find myself extremely confused and frustrated with the whole thing.
Michelin seemed clueless about it and before I even gave them the weights of axle they said put 80psi in all round, when I explained about the weights they said put 50 front and 80 rear, I asked why the big difference when both axles weighed almost the same, and couldn't get an answer ! the person at michelin both on the phone and on the web chat just didn't fill me with confidence especially when I was given the pressures before he even asked what weight I was running, the feedback from him seemed to be the weight didn't matter and the conclusion was kind of 80PSI in the back no matter what, and put what ever is comfortable in the front...
So I reverted to the tyre safe leaflet here http://www.tyresafe.org/wp-content/uploads/2015/12/motorhome-leaflet.pdf , and even called them, but still I can't get an answer.... so here is my problem!
My tyres are Michelin Agilis Camping tyres, 225-70-15 CP with a 112 load rating. My axle weight is Front 1560KG and Rear 1520KG
The second chart on the leaflet has the pressures for CP tyres, but the lowest weight it starts at is 1952KG front and 1736 Rear which is well above my weight. (for this weight incidentally it states 58 PSI all round, which is well off what Michelin are telling me)
The chart above is for normal commercial tyres, not CP tyres, however on this chart my size and axle weights are listed as they go right down to 1400, for my axle weight in this chart I should be using 40 PSI all round, half of what Michelin are telling me.
I am completely lost, I have no confidence in either of these recommendations now,
If anyone could offer an opinion or advice I would be grateful?
At the moment I am going off the lowest axle weight on the CP tyres chart which is 58 PSI all round, and I must admit the VAN does feel good, however the tyres do look soft when you look at them compared to the old ones. the door card is telling me 59 front and 65 rear which contradicts all of the above.
I might be making too much of an issue of this, but I just want to ensure our vehicle is as safe and as comfortable as I can make it, and I guess I am getting myself all wound up because I have taken the advice so often offered about doing it right and getting the weights etc, and now I have hit a brick wall with it!
