24 x 1 3/8 in. (37-540) Primo V-Trak Knobby Wheelchair Tire Purchase Notes
This is a pneumatic tire and requires an inner tube. Choose to add an inner tube with a schrader valve when ordering (a schrader valve is the standard bicycle / car tire type valve). You can choose from a standard or thorn resistant inner tube (thorn resistant inner tubes are made from a much thicker material helping to reduce flat tires caused by a variety of objects such as stones, glass, doorway thresholds, etc). It is best practice to replace the inner tube when replacing a tire since inner tubes can exhibit wear and fatigue especially at the seams with prolonged use. You can also replace the air filled inner tube with a solid urethane insert which turns this Primo V-Trak model into a completely flat free tire (the solid insert is re-usable).
