Just purchased a new 2500 CC 4x4 ,6.4 hemi with 4.10 gears. This truck came with 17" steel wheels and I'm looking to upgrade to Ram OEM 20" wheels. I have heard that this might cause warranty issues, so I called a few dealerships in the Atlanta area, sure enough three service managers told me that would probably void my warranty ! That sure is hard to believe. I could maybe understand it if I was going to put 35's on. Has anybody else heard of this issue ? Thanks
