A 9 inch wide wheel takes a 245 to 265 tire and is the flush width on a WRX, Mustang or Camaro, and the rear width on a lot of staggered 18 and 19 inch sets. Offset decides where a 20x9 ends up. The same wheel tucks at one offset and sits flush at another, and the caliper behind it sets the floor.
847 designs on this site come in 20x9, and the same diameter comes in 10 other widths, 20x10, 20x11 and 20x8.5 among them. Most 20x9 designs are drilled for 5x114.3, 5x112 and 5x120. The same 20x9 sits three different ways at three offsets, so the number that matters is offset against your fenders and brakes. Pick your car and the page keeps only the sets that clear.
