Can I take the tires off my base model steel wheels/hub caps and put the tires on a set of OEM 18" aluminum rims I purchased, or do I need new tires? While I'm at it, do I need new lug nuts to make the swap, and do they cost $9 each? And do tire pressure sensors cost like $90 apiece? What I'm seeing on auto parts sites tells me 'no.' What's the best place to get this done - dealer, tire store, chain mechanical store, mom and pop garage?
