Got it. Saved me a lot of headache I appreciate it!

Ah I see. Thank you for the clear explanation. So rim size is totally irrelevant then no matter which direction?

Hey guys, first time poster. Just got a new 2020 Sierra base X31 for work. I imagine I'll be around here for awhile now. I know this topic looks like its already being done to death, but I haven't see anything specific on this question - will the same size wheels from an older model fit? My truck has the 17" steel wheels with good tires, so I am looking at the older GMC 17's (05+) for a swap. This truck is the base model X31, so I wouldn't think it has oversized brakes or anything. Apologize if this has been answered, all I have mostly seen is people going from bigger wheels to smaller or aftermarket.
