BMW

And if i do get my own rims are the tire pressure sensors still gonna work? if u dont know the answer then dont answer .

You will need to get sensors or move them onto the new wheels. im sure you can get facotry bmw wheels that you like or find anyone to trade you. if you get a bigger rim just make sure you a lower ratio tire to keep it within factory specs. if something does happen; brakes, suspensions etc. they will have to prove that your parts are the cause of the malfunction before they can refuse serveice.
