I just got a used 2019 Stealth, and I've got a set of 18" wheels coming because I detest ultra-low profile tires on daily drivers, and I occasionally go offroad and will be running BFG KO2 all terrain tires. I'll let you all know how it rides when the wheels get here next week, but I expect the 35 PSI for the /65 series 18" wheels will ride much better than the 39 PSI for the /45 series 22" wheels. The 18's have some new tires on them already (takeoffs from a 2022 F150 STX) so I'll be wearing those down before getting the BFGs.
