The objective of this study was to compare the rolling resistance of four common
manual wheelchair tires (two pneumatic and two airless solid) and the solid tires
used on a commercially available force- and moment-sensing wheel. Coast-down
tests were performed with a wheelchair positioned on a
two-drum dynamometer.
Within each of three load conditions, tire type had a significant effect on
rolling resistance (p < 0.001). The pneumatic tires had smaller rolling
resistances and were less affected by load increases than the solid tires. Within
the two tire types, higher air pressure or firmness and lower profile tread
corresponded to less rolling resistance. Wheelchair users, clinicians, and
researchers must consider the effect of tire type on wheelchair rolling
resistance when selecting a manual wheelchair tire.
