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

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.
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.carnut1100;19797 wroteOne 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....

Cheers Ed.PaddlerEd;19901 wroteJames, I think that the 400's had a 4 stud pattern, but not the same as the 93 850... Rob's edit has it all in there...
