The advice I had from VanWeight Engineering was that 15" 112 tyres would need new alloys with a higher load weight than the stock alloys. That is why I decided to go for 16" alloys and initially tyres with an even higher load index. I think it will be most informative to see what the load weight limits are for the stock alloys.
Am still waiting to find out from the Peugeot dealer and Peugeot UK what the load rating is of their 15" stock alloy wheels.  I have also asked someone who appeared to be selling them on-line and the A-S Service Centre but have had no response.  The only way that Van Weight Engineering can say that 112 tyres will need new alloys with a higher load rating is if they know what the load rating of the stock alloy is and that it is less than 1120 kg.  Could you ask them what they think the load rating is and what is their source?

They were very helpful and a small one man band company, They overcame a few little issues with no bother. I have now have plenty of payload and they managed to get the van to 4250KG. I did all the modifications like fit the Drive rite semi air suspension and had new 16inch wheels and tyres from Rogue Alloys. I have upgraded the front springs which was not necessary but i wanted a nicer ride and also it lifted the front end by 30mm. Easy process and not a big deal if you need more payload. If you need any data on the equipment i used just message me.
Out of interest, what have your axles been up-plated to and what size, type and load index of tyre do you now have?  I assume that before up-plating your maximum axle masses were 1850 kg front and 2000 kg rear and you had 215/70 R15 CP tyres fitted with a 109 load index as I have.

Nothing heard from Peugeot yet so I contacted Van Weight Engineering who have said:

"Your rear axle limit is defined by the lowest weight limit, kinda like "a chain is only as strong as its weakest link".
So upgrading your tyres from 109 to 112 won't gain you any additional capacity as the 1352242080 wheels they're mounted to are limited to 1,000kg, and the axle the wheels are bolted to is limited to 2,000kg.

So in addition to the heavier duty tyres, you'd require heavier duty wheels, and fit rear suspension upgrades to increase your rear axle limit, though I'll need some further information to be able to give you the most accurate advice."

So they are adamant that the wheels are limited to 1000 kg.  This is at odds with others' experience (e.g. Plymouthwelshboy) which is that 112 tyres upgrade the weight each wheel can take to 1120 kg and has been used to up-plate the rear axle with the DVLA.  I will press Peugeot again for an answer.

what VWE are saying that both the 15" tyre and wheels will have to be upgraded, i am of the opinion from what i have read about my standard 16"autosleeper alloys are only good for 1000kg per corner, my winchcombe coming from the factory at 3850, but my van is now 4250 i am wondering if they are fitting uprated wheels to the newer winchcombes which are now 4250 out the factory

Just had my wheel off again.  It  has a different Ser No 1374084080 from the one quoted by VWE.  We will see if this makes any difference.

I’ve got as far as I am going to get on this.  I’ve confirmed my OEM 15” wheels are alloys Ser No 1374084080 and a steel spare Ser No 1395239080, which I suspect is the same as others.  They are common to both Boxers and Ducatos and I have confirmed they have no load markings.  On-line parts suppliers, [You must be registered and logged in to see this link.] and [You must be registered and logged in to see this link.] customer care & dealers do not know their load rating but one dealer was emphatic that it is no lower than the highest load index tyre that will fit which is 112 (1120 kg).  This must have been [You must be registered and logged in to see this link.]’s view when they up-plated Plymouthwelshboy’s rear axle from 2000 kg to 2240 kg with 225/70 R15 112 tyres fitted to his OEM wheels.  But VWE are now saying the load rating of the OEM wheels is only 1000 kg, which apparently is the specification declared on the [You must be registered and logged in to see this link.], to which they have access but others do not.  As 2000 kg across the rear axle is the maximum offered by Peugeot/Fiat for 15" wheels, 1000 kg is their default.  If a rear axle gets close to 2000 kg and one wheel exceeds 1000 kg or its 109 tyre exceeds 1030 kg, which is almost inevitable, then it’s the driver’s fault for not loading the axle evenly.  As far as I am concerned, the tyre is the weakest link and especially if it is run continuously at or close to its maximum capacity which is why [You must be registered and logged in to see this link.] recommend that the maximum load on the axle should not exceed 90% of the total tyre load capacity indicated by the load index.  This is one reason why I still plan to replace my Continental 215/70 R15 109 summer CP tyres with Michelin 225/70 R15 112 all-season CP tyres, even though my OEM wheels may on paper appear to have a lower load capacity.  Correctly inflated CP rather than C tyres will undoubtedly help but they won’t increase the load index.  Whatever, it now appears that VWE will only up-plate the rear axle if the OEM wheels are replaced with 16” wheels or aftermarket 15” wheels with a load rating of at least 1120 kg, which I am sure are no stronger than the OEM wheels.  I asked the [You must be registered and logged in to see this link.] if they knew the OEM wheel’s load rating and had no response.  I also asked [You must be registered and logged in to see this link.] and if they required the OEM wheels to be replaced to up-plate the rear axle and also had no response.
