Well, I got my Rough Country 2" leveler (more like 2.5") installed last Tuesday then yesterday I went to the local "Tires To You" tire shop. I ended up buying a new set of wheels and tires. It's size 20X9 and the tires are 35/12.5R20 Sur Trac AT so it says in the sidewall. It's a very inexpensive (cheap) tires but I like the load ratings and it's very quiet. Drove it at highway speed of 75mph and I can barely hear anything considering I'm 70years old with tinnitus issues hahaha. Anyway, the tires seems to be skinnier and shorter to be called 35/12.5 R20. I think it's more like 33/11.5 R20. I have 30 days to decide whether I keep this tires or not. Anyway, the new TPMS that was installed with the set of wheels and tires seems to be not working with my truck. I was told to wait and drive it casually for a couple of days because somehow Ram truck seems to be finicky.
