Tuff Terrain’s spare wheel underbody water tank turns the empty wheel bay into 62L of general water storage, meaning you keep the tray or canopy free for other gear. The octagon shape matches a 28-inch tyre outline, which keeps ground clearance similar to the original spare. Internal baffles cut down water slosh as you drive, so the vehicle feels more settled on corrugations and uneven tracks.

Food-grade polyethylene construction shrugs off mud, dust, and road grime, and the moulded shell handles the usual knocks from stones and debris. A stainless steel sleeve at the 108mm centre hole spreads clamping loads from the winch or mounting system, helping the tank hold shape long term. Two threaded ports pair with the supplied 13mm barbs to hook into your hose setup, while adhesive rubber strips sit between tank and chassis contact points.

Q: Can this tank store drinking water?

A: The tank suits general water storage only, not certified drinking water.

The shell uses food-grade polyethylene, however the manufacturer does not mark it as potable certified. You can still use it for washing, cleaning, and general campsite duties. If you need drinking water storage, use dedicated potable-rated tanks or containers.

Q: Do I need extra fittings to plumb the tank?

A: You may need extra hose, clamps, valves, or a pump.

The tank arrives with two 13mm metal barbs and adhesive rubber strips only. Most setups still require hose to reach taps or a pump, and possibly a breather or isolation valve. Matching all fittings to your existing plumbing keeps the system consistent and easier to service.

Q: Will this fit every 4WD spare wheel mount?

A: Fitment depends on your specific vehicle and space.

The centre hole measures 108mm and suits many winch systems up to 145mm, but chassis layouts vary. Always measure the spare wheel bay, cross-members, and exhaust routing before purchase. Where space is tight, professional installers can advise on brackets and clearances.

Q: How should I protect the tank from exhaust heat?

A: Keep at least 50mm clearance and use heat shielding if required.

Hot exhaust sections close to the tank can soften the polyethylene wall. A metal or high-temperature barrier between the pipe and tank reduces radiant heat. Regular checks after hard trips help you spot changes early. Any signs of warping or discolouration mean you should rework the shielding.

Q: How do I maintain the tank between trips?

A: Rinse, drain, and keep ports sealed when not in use.

Flushing with clean water removes sediment and helps control odours. Leaving the tank dry during long storage periods slows internal build-up. Keeping the inlet and outlet capped or valved off limits dust and mud entry. Periodic checks of barbs and mounts keep the setup ready for the next run.
