o.205
The surface area of the board (without wheels) would be 785 × 205 = 160925 mm2 ================================== Another contributor Anglicized it: Almost exactly 8 inches by 31 inches.
It means that the part of the tire that is in contact with the road is 205mm wide.

They are pretty close in overall diameter as the 205 will be .3" smaller. Your speedometer will be .7 mph fast with the 205. Your engine will turn an additional 10.1 RPMs every mile driven with the 205. The 205 is a good swap if you want a wider tire.
249.075 kg assuming room temperature and purity of aluminum. I ignred the '2mm thick aluminum' as you've already given the dimensions. Density of aluminum taken from wikipedia
well the 205 is 205mm and that is the face of the tire the part with the tread the 60 is the side wall measurement so 60 is 60 percent of the face of the tire and the 16 is the rim size so the dimensions would be, 65.24cmx 20.5cm or 25.68 inches by 8.07 inches
The first three numbers are the width in millimeters, the second set is the height of the tire (edge of the width to the bead) expressed as a percentage of the first number and then R__ is the rim size. For example, a 205/55R16 tire is 205mm wide, (205×.55) 112mm tall with a 16 inch wheel
Okay, the "tyre number" is 205 55 16 (not 2055516). 205mm wide, 112.75mm from wheel to tread (55% of 205) and the center is 16" wide for wheels. So yes, 16" wheels will fit on your audi a3 and they will fit inside your 205 55 16 tires.
