How to find a Weighbridge?

Yes please.  Have an issue with our Ducto based MH, over new year the tyre pressure light came on for front N/S.  We used the Michelin pressure of 65psi whereas the Fiat pressure is 80psi.  Took it into Fiat who said it was a low tyre presssure and once pumped up the light went off.  I explained the Michelin guidance but they would not change the TPMS so just wondering if Peugot have same issues?

I phoned up the local trading standards and asked them where nearest public weigh bridge was - they check them.

OK. Bear in mind this relates to an AS Broadway which is a Peugeot Boxer coachbuilt conversion but there are probably lessons learned for other makes.

The recommended tyre pressures on the inside of the cab door are for the Peugeot, not for the motorhome. Ignore.

The Continental Vanco tyres are marked 69 psi max. This is for the Americam market and not relevant to the UK. Ignore.

Check the recommended pressures for the fitted tyres with the manufacturer. The tyre pressure increases with the axle load so you can guess the front and back max. weight or go to a weighbridge.

You may then find that the recommended tyre pressure is lower than the van low tyre pressure warning - because the van calibration is for the Peugeot Boxer, NOT for the motorhome. 

So you can either increase the tyre pressure above the low pressure warning level (4.5 - 5 bar) and have a firm ride and no pressure warning, or, just live with the pressure warning, or, go to a Peugeot garage and get them to recalibrate the warning level - at your own cost!

I haven't yet decided what to do but I now know a lot more about tyre pressures than the manufacturers main workshop appear to do.

Never for a second have I thought we would ever be overweight, but having booked a long journey down to Croatia and being told how hot they are abroad concerning weight, I thought I would have it checked.

The local grain store does provide certificates at a charge of £10.25.

I filled the diesel tank and my wife was in the van and I found that plus my weight, we still had around 200 kgs to spare.  Then someone told me that the unladen weight takes into account the driver and 3/4 of a tank of fuel..any comments welcome. 

I was looking up the weight inclusion question yesterday and found that the "Mass in Service" weight includes 75Kg for the driver and a 90% full tank of fuel. 

No idea whether Greylag is a caravanner or motorhomer. For motorhomes don't the manufacturers usually state what is included? 

Motorhome manufacturers should quote the Mass in Running Order and explain what is included in this figure. In the past, everyone used the same method of calculating the MIRO but that no longer applies. 

At best a weighbridge ticket from a grain store [I use one] will be within 5% providing the scales are calibrated every 6 months and you use the scales correctly. I think nearly all public weighbridges will be within 5%. I believe the DVSA scales used in roadside checks are within 0.5%. Reich told me the pressure plate they sell to the public for weighing motorhomes and caravans have a 3% tolerance if used correctly and recalibrated every two years.

Anyone concerned about their motorhome weight should have a look at SV Tech's website. Its advice is free.

Our local council was a total waste of time the list they had was so far out of date it was a joke. Went to the area tip and the guy gave us the weights on a bit of paper for free but would have had to charge if we needed a certificate. The web was no use. This was 2016.

For peace of mind it is probably worth weighing a new motorhome once, fully laden. I intend to fill with fuel and 100 litres of water and full gas tank plus the two adults. If we are a bit overweight I will empty out some water as we tend to avoid travelling with a full water tank. We also try and avoid a full waste tank because smells build up.

Further update on tyre pressures following my annual service last week. The very experienced technician servicing the van said .... The tyre pressures on the vehicle are correct and you should inflate the rear to 80 psi.  This prevents tyre distortion if the vehicle is stored for long periods. The service manager said ... I wouldn't drive around with the tyres at that pressure. It would shake you to bits! Either way, the vehicle warning set point can't be changed so you either drive around with a constant warning light or live with a firm ride.

Couldn't make it up could you?
