Maxxis Tube 2.75/3.00-18 TR4 (CSV)

The Maxxis TR4 inner tube is a standard-duty butyl rubber tube sized for 18-inch rear wheels running 2.75-18 or 3.00-18 tyres. It is part of the Maxxis off-road, MX and ATV tube range, built to balance durability with everyday practicality rather than chase the lightest possible weight.

Suited to trail, motocross and general off-road riding, it uses the straight TR4 valve stem, so check that your rim's valve hole and any rim lock arrangement match before ordering. A sensible spare to keep in the workshop or the trail pack alongside your tyre levers.

Confirm the tube size matches your tyre (2.75-18 or 3.00-18) and that your rim takes a TR4 straight valve before fitting.
Inflate the tube just enough to give it shape before installing, so it sits evenly inside the tyre without folds or twists.
Dust the tube lightly with talc or use a tyre-fitting lubricant to reduce chafing between the tube and the tyre carcass.
Use tyre levers carefully and keep them clear of the tube — pinching during fitment is the most common cause of early failure.
Make sure the valve stem sits square to the rim and that any rim lock is tightened after seating the bead; a leaning valve stem indicates the tyre has moved on the rim.
Always fit a new rim band or check the existing one, and remove any spoke ends or burrs protruding into the well.
Set and check tyre pressures to your motorcycle manufacturer's recommendation, and re-check before each ride as tubes lose pressure over time.
Store spare tubes flat or loosely rolled in a cool, dry place away from direct sunlight, fuel, oils and solvents.
Replace rather than patch a tube that has torn at the valve base or split along a seam.
Carry a spare tube, levers and a pump on longer off-road rides.
