I believe the 950 takes 6X15X25 (dont know what the 25 means) and the 850 taks 6.5X15X45. Any ideas?

 

Did a little research, it seems the offset on the FWD cars is bigger than on the older cars meaning that they will rub on the struts n stuff. Only way to make them work is to use spacers. Looking for some chepo spacers or some 940 rims... The tire guy said 2 of mine were bent, and the junkyard only has 850 rims.

 

Volvo changed the suspension on the 900 series to use the same rim offset as the 850 in 1995. Of course, the only 900 series left at that point was the 960, so that's not going to help you any. Parts stores will have spacers... but spacers alone aren't going to get your wheels out far enough to keep handling where it should be- they'll move the wheel out enough that it doesn't rub, but it will still be in too far, which will play havoc with handling, and may even make it dangerous to drive. To get 850 wheels to stick out far enough, you'd have to use spacers to 20mm- that's 2 cm! That would require extra, extra- long lug studs, and even then, it would put WAY too much stress on your wheel bearings, because the load axis will have been moved outward too much. As for your rims being bent... get second and third opinions. That's one of the favorite explanations for trouble that tire people offer. They'll often "prove it" by spinning the tire on the car, and showing you how it wobbles. But quite often, the tire is simply mis- mounted, or has a flat spot, or the brake rotor is warped, or there's a little piece of dirt stuck between the rim and hub, etc. Is it a "bent" flange that won't seal? maybe so... or there's some junk caught between the rim and tire/ damage to the tire bead. Some tire people know this, but use it as an excuse to get you to buy new, "custom" wheels from them. Others- most- are simply ignorant, and assume a bent rim is the cause of a customer's complaint, without ACTUALLY checking the wheel itself. Did your troubles start after hitting a pothole or something? That CAN cause a bent rim... but it usually damages the tire internally first.

 

What happened was The car would shake badly if i drove faster than 65-70, I figured out which wheel was causing it by moving it around, so I figured it just needed balancing or maybe a new tire. The tire had less than 10k on it so i was betting it was balance. The dude at the tire place said that it was a bent rim and it wasn't the balance. I had hit a bad pothole while driving at about 85 down a freeway earlier. It was one of those really long cracks that was wider than my tire, so the car had time to drop into the hole and hit the other side crazy hard. Good idea about the bent rotor or dirt, I will try and check for that. Thanks.
