My 2019 class C came with the exact Hankook tires you mentioned. We are up to about 15k miles and don't have anything negative to say about them, If I had to replace them today and they were competitively priced I would probably buy them again. We camp a lot and will still probably age them out before 45k.
Something I want to share: I also wanted to add a spare as my C did not come with one, so I purchased an OEM Ford wheel as specified by Ford for my chassis by VIN (~$380,) which appeared identical to the factory installed wheels, and a Hankook tire identical to the OEM installed tires ($170.) The factory installed tires are made in Korea and the spare I purchased was made in USA but were otherwise identical. I purchased a steel valve stem from Napa and had it mounted and balanced at the local tire shop. My rig has an interior spare tire storage bin so I tossed it in and didn't give it another thought.
At the end of year 1 (spring 2020) I decided to rotate tires and put the spare on the rear. My FORD brand spare wheel with the identical part number to the chassis-cab wheels installed by factory RUBBED ON THE REAR BRAKES. It would NOT drive with the spare installed on the inner dual. I have to run the "spare" on the outer dual (I did not try it on the front, but the front brakes are even bigger than the rear.) So now I have one of the factory installed tires in the spare box and am running the "spare" I purchased on an outer dual. Reading online, I am not the first one with this problem. The FORD replacement wheels you purchase from FORD parts are different than the ones installed at the factory despite the identical part #.
My advice: If you choose to build a spare tire/wheel I recommend you either try it first or just go ahead and mount it on an outer dual position so a factory-installed wheel is your spare (assuming it will work anywhere.)
