Ok, so yes I've been using the Harley-Davidson Tires on my OCC Schwinn Stingray Motorized Chopper's for quite a while now and just wanted to let others know, that yes it's possible they do fit! Thanks to Sulley from RatRodBikes, for taking the lead and showing us all that it works! The Harley tire is the Dunlop D-402 130/90B-16 or D-MT90B16, these tires can be picked up in the trash pile used at most Harley Dealerships or other Motorcycle shops. Here's the Dunlop Link: http://www.dunlopmotorcycle.com/tir...dson/dunlop-harley-davidson-tire-series/d402/ http://www.dunlopmotorcycle.com/fitment-guide/search?type=fitment&make=11&model=256&year=282&submit= The Harley D-402 is 25.70-inches in diameter and 5.20-inches in width. Here's a couple of pictures mounted on the stock OCC Schwinn Stingray Chopper wheel: I got 6-used D-402 tires from local Harley Dealership for free in the trash pile with plenty of tread for motorized bicycle use: If you have questions or need suggestions just let me know!
