The C-Tug Kiwi Wheels are puncture free solid plastic wheels that will retro fit older C-Tug Carts that came with the pneumatic wheels.
I had the tube tires and they were okay but it was all but impossible to get a chuck on the stem to put air in them. I shopped at a retail outlet for these wheels and they thought they were gold. ACK, Fair price and quick delivery. All problems solved.
The delivery was fast, got what I ordered. These wheels are far superior to the old style. Easy to add the side skirts to widen the stance for sand.
