Pre-1997 with full entitlements.

Transit tipper. Kerb weight 2500Kg. Plated GVW 3500Kg. Plated GTW 6500Kg.

GTW - GVW = towing capacity = 3000Kg.

Question - can reduction in tipper payload be traded for increase in towing capacity to above 3000Kg?

No, I don't think it can.

I agree.

But i have a Ford dealer telling my customer otherwise and i can find no legislation to back my opinion.

I've always assumed, rightly or wrongly, that towing weight is independent of vehicle load weight, otherwise the inverse would be true ie increasing load would reduce towing weight.
I'd be asking the dealer for evidence rather than assume they are correct.
It's a serious thing to get wrong- light vehicle + heavy tow load = instability

I'd say "yes.........but"

There's 6 weights to be aware of, none of which you can exceed:

unit gross weight
unit axle 1 weight
unit axle 2 weight
tongue weight (onto tow hitch)
trailer gross weight
(don't really need to worry too much about relative axle weights for a close-coupled twin or single axle trailer)
gross train weight

Note that, an increase in tongue weight will also increase unit axle 2 weight MORE than the imposed weight, because it acts as a lever and reduces weight off of axle 1 too.

In addition to those 6 which are easily determinable and required to be stated on standardised plates on the tow vehicle, trailer and tow hitch, some manufacturers will also give a maximum trailer weight - but many do not.

ETA there is another weight to worry about - some tow hitches are "heavy duty" and have additional mounting points, heavier metal, more bracing etc. If there are variations and your tow hitch isn't heavy duty, it will have a limit to trailer weight which is possibly lower than that derived from the above.

What is the transits actual towing capacity?

You’re assuming that the towing capacity is 3000kg based on the tipper being fully loaded at 3500kg.

If it’s got a 3.5 ton towing capacity, you could just take 500kg off the pay load.

Not many transit do have a 3.5t towing capacity though.

Define "actual".

In terms of getting prosecuted for anything, I reckon the police can't do much more than look at plated weights, so as long as you're not exceeding any of those you're probably fine.


The actual towing capacity might be more than "GTW-GVW". Should be on the V5 and in the handbook. This isn't unusual. E.g. some L200s have a 2,500 kg difference between GVW and GTW but the towing capacity (according to the V5) is 2,700.


Bear in mind if it's for business purposes you may well need a goods vehicle operators licence.

Exactly what I asked. Don’t be an arse when asking for help.

Your van will have a max braked trailer limit in kg.

The max towing weight and the max vehicle weight sometimes exceeds your gross train weight.

If the van will tow 3.5 ton you know the van won’t be able to weigh more than 3 ton to keep under its GTW.

It’s not rocket science.

Thanks for your reply. I'm told only the kerb weight is on the V5.

The problem my customer has is they have bought a digger/trailer with combined weight of 3300Kg. Which is 300Kg over the calculated weight from the VIN plate.

And as per my original post, they have been told if the tipper were to have reduced payload they can increase the towing weight.

What i have found so far disagrees. And i can find no legislation whatsoever.

As you've found, I don't think there is any legislation to stop this, as long as you remain within all plated weights (including axles). I've tried before to find it as well.


The V5 or Certificate of Conformity should have a maximum braked towing capacity for the "actual" number.

As you've said, not sure how anyone would get prosecuted for exceeding this (but being within plated weights) as it's a hard number to find in comparison.

It's a bit like the recommended roof load that pretty much all cars have.


There could be insurance implications etc.
