Agree with the comment to carefully check all options.
When my father bought a completely new car from dealer, I compared the window sticker to the actual car, and I discovered it originally came with alloy wheels and Michelin tires, yet on the car were steel wheels with simulated spoke wheel covers and Firestone tires...
...after some hassle, took it back and the dealer put on the correct wheels, chrome lug nuts and tires.
Later, I dug out the spare, only to find it was still Firestone. So after more hassle, finally got this dealer to replace the spare with the correct Michelin tire.
BTW, we never went back to that dealer, ever! And while most dealers may be honest, I suggest to use a “trust but verify” approach.
Oh, also, 50 miles is no big deal, though since dealers have a frequent flow of transporters dropping off vehicles, it would not hurt to ask if they can accomplish the movement using one of the car makers transporter... nothing to loose just by asking.
Good luck!
Please let us know how it turns out for you...
