The Force2k-ISC or 4K-ISC models can be upgraded (at an additional cost) to the wider 6.5" Wide Track tyres.
(price discounted to $285 when purchasing with either the Force2k-ISC or 4K-ISC)
They provide class leading levels of traction and stability over solid surfaces (eg concrete, pavers etc). This upgrade is also recommended when moving and turning large & heavy Caravans or Boat Trailers, especially on inclines. Dual axle trailers do not turn easily and the combined 13" of rubber will bite and enable the user to turn a dual axle trailer harder and more aggressively.
Each tyre has a load rating of 355kg and at 6.5" wide is the widest tyre available on the market.
Furthermore our tyres are pneumatic which allows for the contour of the tyre to adjust over uneven surfaces (eg a 1 inch step up onto a garage slab) for optimal grip, compared to using a solid plastic wheel or tank tracks.
