My experience....The dealer will offer you very little for the junk tires on your trailer. Then will want high dollar for the tires that he will recommend...usually something he has in stock. And will sock you high labor rate for installation, and balancing. By the way, they will usually insist on putting on ST tires, (like Goodyear Marathons) which are no better than what is on there now.
Possibly could get them to install Michelins if you push hard. But you'll pay dearly.
Best to strike you best deal without the tire discussion, and then go down the street and get your new tires of your choosing put on at a much more reasonable price.
You'll come out cheaper and with better tires.
