NUEVO/ Lancashire - tyre pressures

[MOTH]

I have got an Autosleeper (Lancashire-) Nuevo , 2007, old shape cab and I have not had it weighed and want to avoid weighing if possible.

I had all tyres at 60 PSI for several months but I have just raised them to 70 PSI. I reckon it has improved the MPG by about 5% but the ride is a lot bumpier, giving rise to more rattles and jolts.

Could somebody give me some feedback as to the pressures that you run on in your Nuevos and Lancashires?

The manual and doorpost says 79.5 PSI, which seems way too high to me.

It's important you get it weighed at a public weighbridge: the manufacturers figures are rarely the same as the actual figure (plus your touring kit and accessories).

 

Compare the figure the weighbridge gives you to the axle weights on the vehicle's chassis plate. It needs to be under.

 

Then contact the tyre manufacturer and get their recommended pressure for the quoted axle weights. Make sure this is under the maximum inflation pressure stamped into the tyres sidewall.

 

Hope this helps.

Hi Dan,

 

Until you get it weighed you can estimate the tyre pressures you need by downloading the info sheet fromTyresafe and looking up your tyre size and approx weight. Make sure you use the right table for Van or Camper tyres though.

Hi Dan,

Had my Lancashire weighed fully load for a two week trip, full tank of fuel, full fresh and waste (forgot to empty it from previous trip) emailed Michelin with the weights and they suggested 55psi rear and 50psi front

Mine is a 2006 version, hope this helps

I'm sorry, but I don't think this is safe advice at all.  Until you weigh the van fully laden, and get the weights on both axles, you have no sound basis on which to use the tyresafe chart.  You may just as well think of a number, double it, take the square root of that, and call it PSI!!  It'll be a calculated value, but totally irrelevant to your van (or anyone else's!).
