Volvo Wheel Fitment Guide
I've done a bit of research (sometimes painful) and can now identify the four main areas to be addressed with Volvo wheels (rims).
Stud pattern, offset, centre bore and stud size. Get the stud pattern and offset right and the centre bore wrong and you are still in trouble. The Standard Volvo pattern used for FWD / AWD from 1990's is: PCD: 5x 108 or 5x 4.25 inches, Wheel Offset: 35 to 50mm and Centre Hub Bore: 65.1.
While the XC90 has the same PCD: 5x 108 or 5x 4.25 inches and Wheel Offset: 35 to 50mm the Centre Hub Bore is: 67.1mm so significantly larger than the 65.1.
The S40, V50 and C30 from 2004 onwards has the same PCD: 5x 108 or 5x 4.25 inches and Wheel Offset: 35 to 50mm but the Centre Hub Bore is: 63.4mm so a little bit smaller.
It now appears the all post 2008 V70T6, S80, XC70,S60 and V60 have the same smaller Centre Hub Bore of 63.4mm.
Also the latter model Volvos have a 14mm wheel bolt instead of the previous 12mm.
So if you want to mix and match you will need to get Hub Centric Rings to suit (of course you can only go down not up so you can not fit the 63.4 mm Centre Hub Bore rims onto early Volvos with the 65.1mm Centre Hub Bore).
The following are the sizes in Hub Centric Rings you will need 67.1 to 65.1mm, 67.1 to 63.4mm or 65.1 to 63.4mm.
While it may not look a huge difference in size you will get significant imbalance making the car un-driveable and since Volvo use bolts instead of fixed studs it is impossible to even try to centre the wheel (plus one bump and they will go off centre).
Hope this helps and stops you having the same problems I have experienced.

|---|---|---|---|
| 850, S70, V70, S60, XC70 | 5x108 / 5x4.25 | 35-50mm | 65.1mm |
| 850 | 4x108 / 4x4.25 | 35-40mm | 65.1mm |
| XC90 (2003-2013) | 5x108 / 5x4.25 | 35-50mm | 67.1mm |

| 440, 460, 480 (1986-1997) | 4x100 / 4x3.94 | 35-45mm | 52.1mm |
| Model | Ring size |
|---|---|
| XC90/XC60 -> 850 | 67.1mm -> 65.1mm |
| XC90/XC60 -> S40 / C30 | 67.1mm -> 63.4mm |
| 850 -> S40 / C30 & later 2008 models | 65.1mm -> 63.4mm |

It doesn’t cover all but is a good cross section and is from a Volvo accessory brochure

I also have the above as a easier to read PDF if anyone wants it.
Don't know about the bolts, if the under side of the head has a taper seat they will also seat fine.
If they are a flat seat then the need the hubring to centre.
One bump and they will go off centre?
Not quite........
Contrary to what many think, hub centring rings do NOT support the weight of the car, nor do they take any of the shock loading from bumps......they are there purely to centre the wheel on installation.
I was curious a while ago and dragged out the old formulae from when I was studying engineering, and ran the numbers. Of the top of my head I can't recall the figures and it's too late at night for me to run the numbers again.... But if they were carrying the load, firstly they would deform under static load and secondly they would shear right off at the first decent bump........not to mention that one decent clutch dump would shear the studs right off!!!
The load is carried by the friction between the wheel face and the hub face while under the clamping force of the studs.....
In fact, I have seen plastic hub ring adapters....
Can the mods @Rob update the OP so it's a bit more readable, make it more a spreadsheet format please?
Need more spacing on the end of paragraphs @jamesinc
Any ideas anyone?
I regularly use Bob Jane TMarts here in Geelong and they have even sent out wheels for straightening for me, so no doubt they're be able to send some out for centrebore work.
Recently, I had the sleeves machined out of my Titans. 5 sleeves cast into each wheel. Total to machine them all was $140 which I thought was reasonable, ie $35 per wheel.
On the FWD Volvos with bolts even if you were to centre the wheel perfectly which is almost impossible they can still become imbalanced. You are correct that hub centric rings centre the wheel but they also keep it centred. Have had not problems with plastic hub centric rings, in fact am using XC90 17inch rims with plastic hub centric rings now on my S70R and no further problems (XC90 rims are much stronger than Volans). Just got a set of S60R 18inch for my V70T6 and without hub centric rims it vibrates above 75kph, with hub centric rims its smooth again. From an engineering perspective there is a difference between alloy rims and steel rims. Steel rims have a shaped stud hole with a 'coin' to centre and hold the nut, alloy rims do not have the same shape and do not have the coin so the hub does more than you think.

Cheers Ed.
I shouldn't be so down on having your wheels centred, you would be silly not to have something to help locate the wheels in the centre and persuade them that that is where they should stay.
But they DON'T take the load of the car.
Steel or alloy, the wheels are held in centre once fitted purely by the friction force between the wheel and hub face.
Seriously, the torque of a full power launch would shear off the studs if it wasn't for the friction force holding it all on...
Friction is stronger than you think.....
