Yes, that's reasonable.
what is the diameter difference from a 205/65/16 vs. 225/60/16
Doubtful, the 225/65 tires are narrower and shorter.
Yes, you can There will be about a 5% decrease in the tire diameter. 225 65 tires are 225mm wide and 146.25mm in height (65% of the width), while 215 60 tires are 129mm tall, which will affect the odometer and speedometer. When your speedometer reads 60 mph, you'll actually be traveling closer to 57 mph. Replacing the 225 65 tires with 215 70 tires would keep the diameter almost the same (150.5mm).
Two options; 215-65 15 or 225-60 16

Yes, that is acceptable but a better replacement in a 60 series tire would be 225/60-15. Either will work though.
215/75-15 225/70-15 235/65-15 245/60-15 265/50-15 Check for clearance issues on the 65, 60, & 50 series tires.
That's pretty close. The 235/60-18 has a diameter of 29.1" (739.2mm) and the 225/65-18 has a diameter of 29.52" (749.7mm) and a true 60.85mph on a speedometer reading of 60
225/75-16 or 255/65-16
No you should not you use 225/75-16 on a car that came with 215/65-16. This is a 7.79% difference in diameter which is never recommended. You should never go over 3% difference. Your speedometer will read 55.3 at a true 60 mph. Your handling, braking, ride, and performance will suffer with this size. There is no 75 series tire that will work well on this vehicle. You can however switch to a 195/70-16 if you are determined to go with a different series tire. I would recommend you stick with the OEM size.
Can u put 225/75/r16 on in sted of 225/75r1
Yes, you can but your speedometer will be 1.8 mph to fast. A much better swap would be 225/65-16.
