what is the diameter difference from a 205/65/16 vs. 225/60/16
No, there is a 3.15% difference in overall diameter. This will cause your speedometer to be off 2 mph.
17 inch diameter rim versus 16 inch diameter rim
No, there is too big a difference in diameter.
The larger rear tires get better traction in the mud and rough terrain. The front only needs to steer.
Yes as long as you keep the overall diameter the same. For instance you would replace a 185/75-15 tire with a 215/65-15 tire which would keep your overall diameter almost the same. Click the link to calculate what size tire to go with.
You'll most likely be buying rims with a larger diameter such as 19 or 20 inches. Your existing tires will need to be replaced with a tire that will fit on your rim.
the 16 and 17 refer to the tires diameter hence a 17 is one inch taller than a 16 inch tire
They will of course fit but there is a problem with going to a larger diameter tire. Your speedometer will be off. A much better replacement would be a 195/60-15 which is almost the exact same diameter.
Yes, if you install the correct tires and use 16" rims/wheels as well. Install tires that end up giving you the same overall diameter as the OEM 15" tires. You can use a tire size calculator to determine the size tires you need.
28 in. diameter tires
The equivalence is 225 50 R18 so that the diameter may be the same.
You can but it not a good swap. The 65 series tire will be 3.15% larger in overall diameter. It is never recommended to go over 3% difference. Your speedometer will read 58.1 at a true 60 mph. Performance and fuel mileage will be adversely effected.
