The HOOPER 2DW:Specifically designed for used on trailers with dual wheel applications including flatbeds, hay haulers, dump trailers, car haulers and more. Replacing your 235/80R16 or 235/85R16 tires to a genuine commercial grade wheel and tire has never been easier. The Hooper can fit either a 225/70R19.5 tire (32" O.D.) or a 245/70R19.5 (33.2" O.D.) Both size tires provide you with improved low-profile performance, lower rolling resistance, and improved stability when maneuvering and when traveling down the road. You won't have any of the sidewall flex and sway issues that you experience with a high profile tire.
