Rear Wheel Assembly for the Heartway Vita S12 and Bien S15 Size:13"x5" as is the axle keyWhen you need a new rear wheel assembly for your Heartway Vita S12 or Bien S15 scooter we give you a choice. The Heartway Vita S12 mobility scooter comes from the factory equipped with a standard 13" x 5" wheel, however Heartway also offered an optional 14" wheel as well. The 14" wheel assembly makes a perfect substitute; however the slight difference in tire size means that you should always replace both sides at the same time. Heartway: HW 94219024
