Rim Swap 20 to 18 Advice

[Mainewoods]

Hey guys,

New member looking for some advice. I have a 2019 1500, it came with 20” rims. -19mm offset, 275/55r20. I hate the rims and want more rubber so I can hit a rock without damaging anything. Was looking at some 18” rims with 0 offset. Which would in theory push my tire out, right? My other question is the caliper clearance. From the current 20” rim to the caliper, its about 1 5/16” of an inch. Would swapping down to 18”s rub? Or affect brake cooling, anything else stupid?

Thanks for the advice

Stock size on the Bighorns is an 18' rim so no problem.

stock rims will fit after market are a guessing game,
a lot of offset change can result in tire to fender clearance issues
