Hi Guys,

I have a Ducato 230 motorhome, that is in need of a new set of wheels. The rims are in very bad shape. I have been given a set of brand new wheels that I thought fittet, however have proven to be 5x130 rather than the 5x118.

I came accross a set of adapters:

https://www.ebay.co.uk/itm/PCD-whee...t-5x130-78-1-Ducato-maxi-wheels-/223572256514

Are there any concernes in using adapters for me to be able to fit the wheels?

Thanks

Best to check with your vehicle inspection unit , most of Europe insists on items being "original " with no deviations, upgrades , modifications from when the vehicle left the factory to your countrys marketplace , in the uk people getaway with things that would be thrown out elsewhere .!!!

Not insurance whose they don't they will lookout for anything to put premium's up or knock money of a payout



Legally inspection wise our Mots are fairly lenient especially against the Germans
 
The parts you show on the website are in fact a form of wheel spacer as opposed to a PCD variation wheel bolt kit.

The variation kits will only work with a small difference in PCD, such as 98 to 100 when a BMW 3-series alloy wheel is fitted to a Punto mk1/2 hub, and they will probably be frowned on by testers despite there being nothing whatever unsafe about them, as the wheel is still correctly centred and firmly clamped against the hub register.

Wheel spacers are also fine as long as the increase in width is not excessive, say 1/2" maximum, but again testers might say no. In Spain I would not present a car for test with either, but in UK individual testers may be more approachable, ask them first.

With either the wheel centre hole must be a good fit on the hub spigot to ensure the hub carries the load and not the wheel bolts.
 
My advice...steer clear of wheel spacers especially stuff sold on ebay and no doubt made in China ...last thing you ever want to see is one of your wheels overtake you .
Adaptors to alter PCD are even more suspect ...just get wheels that fit properly it could save yours or another persons life .
 
Remember, all the drive and braking forces are taken through the wheel studs. They are not just there to clamp the wheel on.
Adding another set of studs, which may not be of the same tensile strength as the originals, and a spacer of unknown specification is a risk.
A spacer will move the wheel outwards. Original wheels are designed to place the load over the centre of the wheel bearings. Unless the new wheels have a greater offset to retain the load at the centreof the bearings, those bearings will experience loadings they were not specified for. Wheel bearing life will be reduced, and may lead to sudden failure.

Have a look at these guys: https://www.oponeo.co.uk/alloy-wheels
They are based in Europe, so one of their websites will probably despatch to you.
I chose a vehicle at randon, so may need changing to yours.
Making the wrng wheel fit will never be the 'bargain' they seemed.
Oponeo will supply steel wheels too.

Any wheel or wheel spacer must be a good fit on the hub spigot. If not then the weight is taken by the studs and not by the centre spigot.

Those plastic cones to make up slack between wheel or spacer and hub are to be frowned on, I would not have them on my car.

Wheel spacers which carry their own set of studs or tapped holes for bolts are to be frowned on especially out of aluminium which is not strong enough for such duty.

Only spacers using a longer stud or bolt in the original threaded holes can be safe, and only then if limited in width, say 1/2" maximum. The point made about the wheel being centred over the bearings is important hence the maximim width suggested.

The PCD variation bolts which are sold are safe provided the wheel fits the hub spigot exactly, the PCD difference is small say 2mm maximum, and the cone angle of the washers matches the cone angle of the wheel stud holes. I have a Punto MK1 with BMW 325 alloy wheels using PCD variation bolts and I consider it as safe as the makers setup.

The Spanish ITV testers would I suspect not agree hence I swap wheels for the annual test.
