Yes, you can mount 225-60r16 tires on a rim made for 215-65r16 tires.
No, 21570R15 the 15 means that tire fits on a 15 inch rim 21565R16 the 16 means 16 inch rim.
It provides a mount for the tire.

No, the R15 means that it is a radial tire and the 15 is the rim size. Never try to mount a tire and a rim that are different sizes.
Of course you can.
To mount a bike tire properly, first deflate the tire completely. Then, place one side of the tire onto the rim, starting at the valve stem. Use tire levers to carefully push the other side of the tire onto the rim, being cautious not to pinch the inner tube. Inflate the tire to the recommended pressure and check that it is seated evenly on the rim before riding.
To mount a bicycle tire, first remove the wheel from the bike. Deflate the tire completely and use tire levers to remove one side of the tire from the rim. Place the new tire onto the rim, starting at the valve stem, and work your way around the rim, making sure the tire is seated properly. Inflate the tire to the recommended pressure and check for any bulges or unevenness. Reinstall the wheel onto the bike and you're ready to ride.
No, you cannot fit an 18-inch tire on a 17-inch rim. Tires are designed to fit specific rim sizes, and an 18-inch tire requires an 18-inch rim for proper installation and safety. Attempting to mount an 18-inch tire on a smaller rim could lead to damage to both the tire and the rim, as well as potential safety hazards while driving.
Mounting a tire on a rim by hand is extremely difficult. I would suggest taking it to a shop and having them do it.
On a machine specifically designed to mount tires on a wheel.
no that would be a mount or a tire or a rim.
No, because inflation moves the edge of the tire outwards on the rim so it becomes tight.
