Schwinn's steel rims were more resistant to twist than a lot of others in the day, due the sheet metal having been formed so as to create more little tubes in the cross section. That's what they meant by "tubular." That distinguished them from say, Rigida steel rims, that did not last as long IMHO. You often needed a special Schwinn-design bead for those rims.
