I've heard that if you switch your rims then you need to get an adapter kit if you are going to a larger size of rim is there any truth to this. I'm getting a damn good deal on some rims. I have 15's on my car now and this guy will sell me his 16's for $50 a piece and all are in perfect condition. Do I need to get an adapter kit so the 16's will fit on my hubs? Or have I mis-heard any info. I would like to get some 17's or 18's on my car but I don't want to have to spend $200 per rim. Thanks
