A 13 inch wide wheel is a drag and show rear width and takes a 335 to 355 tire. Offset decides where a 21x13 ends up. The same wheel tucks at one offset and sits flush at another, and the caliper behind it sets the floor.
14 designs on this site come in 21x13, and the same diameter comes in 7 other widths, 21x12, 21x10.5 and 21x9 among them. Most 21x13 designs are drilled for 5x120, 5x105 and 5x108. The same 21x13 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.
