Total agreement. My point was based around balance or imbalance issues only. For the uninitiated there are Hub Centric and Lug or Stud Centric wheel / rims.
Early Volvo's are lug / stud centric, that is by putting the correct rim on the axle and tightening the wheels nuts in the correct sequence and to the correct torque, the wheel / rim will be centred. Simple no problem.
Later Volvo's 850 onwards are Hub Centric, that is the hub is of a specific size and tolerance to centre the wheel / rim onto the hub. If the wheel is not centred on the hub even tightening and torqueing the wheel / rim in the correct manner will not centre the rim. Problem is imbalance resulting in significant vibration and drivability issues.
This is from a US racing site: "Hubcentric centers the rim on the register of the hub and the lugcentric rim is centered by the lug nuts. If you have the choice, run the hubcentric, less stress on the studs and lug nuts".
Using the list provided you can see if you may have problems or not but a word of warning to the uninitiated;
even if you have the correct stud pattern, off set and centre bore, not all Volvo rims are compatible across the models.
Case in point is the 740HP Gemini rim. This rim has thick spokes and does not fit early 240's (probably 140's and 164's either) without the use of a 5mm spacer. The wider (thicker) earlier brake callipers foul on the inside of the Gemini rim. The sudden nice shiny look of your callipers is an indication of a problem.
I also note that later 960 / S90 models will not accept all Volvo rims with the slight difference in offset enough to cause fouling when turning the front wheels.
The whole idea was to provide a guide of what may or may not work across the Volvo range and maybe save you some dollars.
