Hi i own a 2000 S40 and i am lookin to put some nice rims on i am just wonderin what are the largest rims that can fit and what size do you recomend??

I reccomend 17" to 18". I bet you can fit 19's, but the ride quality will be crap.

try an searching the internet for volvo wheels (http://www.autopartsdeal.com/volvo/wheels.html) mods..I guess if you want to change the rims, so are the tires too.
