I bought some 18 inch wheels off of Ebay the other day. Didn't even think about a weird lug setup on Volvos. Have most of you just used your factory bolts for aftermarket wheels, or does it even apply to S60's?

 

S60's use lug bolts - you should be able to use your existing lug bolts on these wheels. If you can't and have smaller holes on the rim, then you may need to buy "tuner lug bolts". I just found all this out as I couldn't fit a rim onto my S60. My problem was that the new wheels had a smaller center hole than what I required. Now have to get that bored out.

Cheers
