I put a Poison Spyder rear bumper on my 2018 Wrangler JKU. It has an option for their swing-out tire carrier (way too expensive IMO). I think to get a swing-out tire carrier, you will need a new aftermarket bumper and then it makes perfect sense. But I will stick with the factory installed tire carrier designed to carry the 35's.
