Moped Army

Im working on a project puch that I am planning on putting white wall tires on. I know that sava makes whitewall tires in 16" but not 17". I was wondering if puch made 16" wheels so I can put the white-walls on them. I thought I could use a sachs front wheel but for the rear I didnt know because of the pedal chain that puchs require. Also if this doesnt work does anyone know a company that makes 17" white walls?
