I have a 2008 Altima sedan and wanna put some BMW M6 rims on it but dont know if they fit

Even if the bolt patern was the same, BMW is "special" and doesnt use lugnuts like every other car in the world, they have bolts that screw into the hub, rather than studs that pass through the wheel, and get lugnuts screwed onto them.

If you try to screw on a bmw reim with lugnuts, chances are the studs wont pass all the way through thebmw rim, AND if they did, the wheel wouldnt center properly becaue there is no self centering cone for the lugnuts to slide into.

Stop The Rice

No they will not fit...the bolt pattern for the M6 is 5x120...as for most BMW, while the Altima has a bolt pattern of 5x114.3...the BMW M6 requires a medium offset wheel while the Altima requires a higher offset...

and like the guy below me said, the BMW wheels require bolts that screw in into the hub unlike other cars where the studs are staionary on the car...duh, I drive an Audi, I should know this....
