I have a 2016 sxt with stock 18s. A buddy gave me the 20s off his RT. Can I get 265 50 rear and 255 45 fronts and be ok? Do I have to get it tuned or anything? I want the older school look and I drive about 30k miles per year so I want a smoother ride. I don’t race I got it for looks mostly. I could maybe go 255 50 all the way around too if that would be more practical. Any help would be appreciated. My rears now are almost bald.
