To remove a tire, use a lot of soap, tire spoons and rim protectors.
The trick is to squeeze the tire on one side with clamps to have more room on the other side. This is for removing and installing.

To install a tire, inflate the tube slightly and put it into the tire. Adding the tube later is difficult and can result in a twisted tube.
Add soap.

Use a tire pusher tool to push the tire over the rim of the wheel.

Using a tire pusher tool makes the process very easy. Using tire spoons require some space between tire and rim and can make installation more difficult. Especially with the stiff side car tires.
A tire pusher tool does not require this space.

I built a tire pusher tool using an old axle, several pieces of plastic and a rectangular tube steel for the handle.
