CPeachey Posted January 20, 2014 Share Posted January 20, 2014 I had the van weighed today at the council MOT workshop, on the "rolling road" (not a weigh-bridge) Front 1530kg rear 1250kg. Allowing for a bit of luggage Continental's tech document suggests 52psi front for 1600kg axle load and 44psi rear for 1350 axle load. These pressures seem rather low so I am wondering if the weight was correctly shown. van is a Trigano Tribute 05 Ducato 2.3ltr hi top van conversion. Does anyone have any comparable figures please?

gocro Posted January 20, 2014 Share Posted January 20, 2014 Take that as a start and rejoice in the fact you have a van with ample payload. If you want to you can always tweak it in the up direction safely, my previous van was a 2003 Trigano and I ran it around 52/55 as I had a moped on the back.

colin Posted January 20, 2014 Share Posted January 20, 2014 In what state was the van weighed? Have you allowed for driver and passenger, tank full of fuel, tank of water, full gas, fridge and cupboards full of food, then all the other 'junk' most people seem to carry?

Keithl Posted January 20, 2014 Share Posted January 20, 2014 Chris, Ask to see the calibration certificate for the weighbridge then you will know whether it is accurate or not. If they do not have a certificate then suggest you get it weighed again elsewhere. Keith. Link to comment Share on other sites More sharing options...
gocro Posted January 20, 2014 Share Posted January 20, 2014 Went back to look at the Tribby Forum and found the post I did then, the weighbridge is used extensively by farm vehicles and is well maintained and certified. I took my 2003 van to the weigh bridge with a full load just before we set off for hols last year.Our scoot only weighs 75kg but the carrier must weigh about 40kg(very heavy duty beast) results front axle 1480kg rear axle 1420kg total weight 2920kg this leaves around 400kg spare for bringing back vino. The Trigano van has a VERY good payload. Get onto the forum Peachy http://www.tribby.co.uk/ Link to comment Share on other sites More sharing options...
CPeachey Posted January 20, 2014 Author Share Posted January 20, 2014 Thanks GOCRO, looks like my weights are probably right. Van was ready for a trip but without personal luggage and passenger. Water tank was full. Just need to confirm the right tyre pressures now. (I am on the Tribby forum) Chris Link to comment Share on other sites More sharing options...
Brian Kirby Posted January 20, 2014 Share Posted January 20, 2014 But, do you know how the passenger and luggage weights will divide between the axles? I'd say either get it weighed again but with its full and final load, or else make a generous allowance on both axles to cover the unexpected. Using higher pressures won't cause problems, but if you're going to adjust the pressures to suit the load, you need to be sure you won't end up running under inflated, which can lead to trouble.

Van was ready for a trip but without personal luggage and passenger. Water tank was full. Just need to confirm the right tyre pressures now. (I am on the Tribby forum) Chris It depends what you mean by "the right tyre pressures". Choosing pressures that match a motorhome's 'in use' axle loadings won't necessarily produce superior on-road behaviour or improve tyre wear. Unless your Tribute has a particularly harsh ride, or handles/brakes oddly, you might as well adhere to the motorhome's recommended pressures (55psi(F)/65psi®?) At least then you wouldn't need to be concerned about the accuracy of a rolling-road or weighbridge's measurements. Link to comment Share on other sites More sharing options...
Billggski Posted January 21, 2014 Share Posted January 21, 2014 Just been to the weighbridge, 3480k with holiday load and just the driver, which seems fine for a 3850k plated Dethleffs A5881. But the rear was 1940k, and any extra "stuff" will go in the rear garage. The Fiat handbook says 5bar front, 5.5 bar rear which seems extremely high.
