my folks 2015 MD Titanium ecoboost did 34K Continentals and had a few big intrastate drives, they have Michelin PS4 currently.

I get 35K from PS4 and previous PS3 but that can easily jump to 50K if you're driving on the hwy a lot. I don't have a problem with 35K on PS4 for what they give and when on sale end up being $155ea (235/4517 97XL) which is great value.

I rotate mine every 15K (service interval)
I rotate folks every 7.5K (during a half service)

They don't get a wheel alignment unless there's a problem with tyre wear or in my case, some work were done. (suspension)
