CST C62 20 x 1 3/8 (37-451) wheelchair tire
Small rear wheels are common on paediatric chairs, and replacement tires in 37-451 are not always easy to source. The Cheng Shin C62 covers that size with a shallow street tread meant for both indoor floors and pavements. It is made of grey non-marking rubber and rated to 65 psi. The retailer offers it alone, with a standard tube, or with a thorn-resistant tube.

CST C62 20 x 1 3/8 (37-451): common questions
Is a tube included?
It depends on the option chosen. The source sells the tire alone or bundled with a tube.
Which rim does it fit?
A 451 mm bead seat rim, usually labelled 20 x 1 3/8.
Is this the same as a 20 x 1.75 tire?
No. A 20 x 1.75 tire uses a different rim diameter and will not fit a 451 mm rim.
