I have a 2019 ram 1500 sport , it has 22' 6 bolt rims. I want to get separate winter rims and tires, but I don't want to put 22' winters on, was wondering whats the smallest size rim I am able to put on , I had 17' winters on my 17 ram 1500 with stock 20's. If anyone has any info that could help me out I would appreciate it.
