I've calmed down considerably since posting my rant. I've also discovered some useful information. First of all, no 2015-2020 body style that has adaptive cruise also has a " regular " cruise function, at least not according to my dealer. Secondly, the Cooper tires were warranted and will be covered for the vast majority of the replacement cost. They were defective, and not caused by the 22" rims. I'm replacing with Goodyear wrangler HT Kevlar. Hopefully, I'll get some life out of them.
Next, I'd like to address some of the comments made on here.
Premium gas is recommended, not required. There's absolutely no harm to this engine using regular, other than it will put out.less horsepower. Mercedes says premium fuel REQUIRED. You will get a check engine light before you go 5 miles.
Also, I take very good care of all of my vehicles, that's why I was frustrated with the issues. I've never had to crack open an engine on anything I own, but if I did lose an engine or transmission, I have the ability to pay for a new one. My truck is free and clear. I'll never be a slave to a car payment again. I have the oil changed with the factory spec and always with at least 20 to 25% life left on the oil life indicator.
As far as the electronic issues go, I'll learn to live with them. It'll still be cheaper than trading, and after researching, most of the gmc yukons are already denali trim.
