Trailering is without a doubt the best way to bring your treasure home.
You may then replace the tires at a known reputable shop.
Then give it a thorough evaluation.
Then you may begin the local shakedown drives, expanding your route as your confidence with the car builds and no anomlies are encountered.
Far less stress on both the car and the new owner!
Good luck and post up some pictures of your fun trip and of the car once safely home.
We are here to help whenever questions arise.
