Wheel size

[obxfishwagon]

First post here and I haven’t got the search thing figured out yet so my apologies if this has been discussed before. I have a 2016 1500 4X4 with a hemi with 20” rims. What is the smallest diameter rim can I run?

17" was the standard size for many hemis with 20" being the optional size. i have seen someone mention make sure brake calipers will clear if using a 17" wheel but I assume that applies to aftermarket wheels as a possible concern. the stock 17's must have been designed with that in mind.

Considering that the rotors are 13" in diameter, highly doubtful you find a rim less than 17" to fit. That leaves 2" for the caliper, rim thickness and the gap between them.
