An 11.5 inch wide wheel takes a 305 to 325 tire and is a rear width on a C7 or C8 Corvette, a Hellcat widebody or a GT500. Offset decides where a 20x11.5 ends up. The same wheel tucks at one offset and sits flush at another, and the caliper behind it sets the floor.
60 designs on this site come in 20x11.5, and the same diameter comes in 10 other widths, 20x9, 20x10 and 20x11 among them. Most 20x11.5 designs are drilled for 5x120, 5x114.3 and 5x112. The same 20x11.5 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.
