RAILBLAZA C-Tug Kiwi Wheels, Puncture-Free Replacement Set of 2

If you've dragged a loaded C-Tug down a gravel ramp enough times, you know the wheels take the beating. These are the Kiwi puncture-free wheels, sold as a set of two, and they're the same hi-grip wheels that ride under the RAILBLAZA C-Tug cart. When your old pair wears down, cracks, or just won't roll straight anymore, this is the replacement set that gets you back to hauling.

The big thing here is that there's nothing to go flat. These aren't pneumatic tires, so there's no tube, no valve, and no air to lose at the worst possible moment. The wheel is a solid puncture-free design, which means you can roll it over oyster shell, broken pavement, or a sandy path without babying it. No pump needs to live in your gear bag for these. That's the whole appeal of a puncture-free wheel. It trades a little cushion for the certainty that it'll always roll.

Each wheel measures 10.3 inches across and 3.6 inches wide, with a hi-grip rubber tread wrapped around the outside. That width matters. A wider contact patch keeps the cart from digging in as hard on soft ground, and the rubber tread grips better than bare plastic on a wet, slick launch. The center bore runs 1 inch in diameter and 3-1/4 inches long, sized to slide right onto the C-Tug axle.

There's a reason paddlers put up with dragging a cart at all. It saves your back. A C-Tug lets one person move a hull that would normally take two, and it only works if the wheels keep turning under load. Solid wheels shine here because a flat at the ramp ends the trip before it starts. With these, you load up, strap down, and roll, no air pressure to check first.

The hub is molded from UV-stabilized fiberglass-reinforced plastic in black. The UV package is the part that earns its keep on the water. Sunlight is hard on plastic, and a wheel that sits on a hot dock or in an open truck bed all summer needs to hold up. The fiberglass reinforcement adds stiffness, so the wheel keeps its shape under a fully loaded cart instead of flexing and wobbling.

The C-Tug built its reputation as a knock-down cart that folds flat and carries a real load, and the wheels are what make that possible. They pop off without tools, so the whole cart packs down into a hatch or a trunk. Keep that in mind when you order. This set is just the two wheels, so your existing axle, cradle, and frame stay put, and only the worn rolling stock gets renewed.

Who's this for? Anybody running a RAILBLAZA C-Tug who's ready for fresh wheels. Kayakers, canoe paddlers, small-dinghy owners, and anglers who wheel a loaded hull from the truck down to the water all lean on the C-Tug, and the wheels are the part that wears. Buying them as a set of two means you replace both at once, so the cart rolls level instead of favoring one tired side.

Swapping them is straightforward. Pull the retaining pins, slide the old wheels off the axle, and push the new ones on. No tools, no special skills. And because they're solid, there's no bead to seat and nothing to inflate. A quick freshwater rinse after a salty launch keeps the bore clean and rolling easy, which is just good practice for any gear that lives near salt water. If a wheel ever starts to squeak on turns, a dab of marine grease in the bore quiets it down.

One honest note. These are replacement wheels, not a complete cart. If you don't already own a C-Tug, you'll want the full cart first. But if you've got one and the wheels are worn out, this set of two is exactly what you're after. Puncture-free, UV-stable, and built to keep rolling.
