I got a pair of 18"s from a 2009 LS460 that I want to put on my SC300. I asked Discount Tire about getting wheel adapters to convert the 4 x 14.4 to 4 x 120, but the guy there was pretty strong in his conviction that if I put wheel adapters on my car, I had a good chance of dying while driving on the hwy at 80 mph because of the wheel falling off and rolling away from me.
Are they just trying to get me to buy new rims, or is this actually a threat? I've read places that say the stress on the lugs is the same and others that say otherwise. I figure with newer technology, they wouldn't have the same adapter issues had a few years ago, etc.
