Also following along, great work so far - this generally interests me - for my own knowledge, the data is coming direct from the bluetooth OBD2 that is only displaying through the app and the app isn't actually 'storing' any data? I'm thinking through this from a Cyber perspective and privacy...
I had 35x12.5x16 Ridge Grapplers on my Rubicon (before coming to the 4R side) - For those that said they are quiet, give them time. They will be louder. That said, when my factory set wears off, I'll look at Scorpion or going back to the Ridge Grapplers again, they handle well in most situations...
This happened to my ORP hybrid also, took a month to come from Japan, then sat at port for about 3 weeks and several prices went up. The dealer kept the already negotiated price no issues.
