205 is the width of your tire the 65 is an aspect ratio that determines how tall the tire is compared to the width

The width, by 10 mm
The answer is 205 feet.
There are 30.48 centimetres in one foot. Therefore, rounded to two decimal places, 205 centimetres is equal to 205/30.48 = 6.73 feet.
You can't convert that.
The 65 series tire will be wider if both sizes are equal. Example is 205/70-15 versus 205/65-15. The 65 series will be wider but have less overall diameter. The series of the tire is a height to width ratio. A 65 series tire has a height that is 65% of the width, so a 205/65 tire is 205 millimeters wide and 205*.65=133.25 millimeters tall (rim to tread). Since it's usually not recommended to change tire diameters, if you want to go wider or narrower you need to change the width and series. For instance a 205/70 will have almost the same diameter as a 225/65.

e.g 205/55R16, the first set (205 in this case) is usually the tread width in millimetres, the 2nd set (55) is the percentage of the tread width which defines the sidewall height, 3rd set (16) is the measurement for the rim size, and the R means Radial.
