How does tire pressure affect distance traveled by a bicycle coasting to a stop?

[QUOTE="erobz, post: 6662025, member: 700856"] So, it's actually a torque from the offset normal force, and ##c_{rr}## scales the offset, so we can just use ##R## as the moment arm? So its manifests as a torque, but not a force in the direction of motion. $$ \circlearrowright^+ \sum \tau = f_{sf} R - c_{rr} m g R = I \frac{a_{cm}}{R} \tag{1} $$ $$ \rightarrow^+ \sum F = -f_{fr} = m a_{cm} \tag{2} $$ Combining ##(1)## and ##(2)##: $$ a = \frac{ -c_{rr} m g R^2}{ I + m R^2} \tag{3} $$ This at least has the characteristics we should expect of a wheel coming to a stop under its own loading. The OP in [I]principal[/I] could use a [B]modifed[/B] version of this measuring the stopping distance ## x ## at a certain tire pressure ##P##, and make a ## c_{rr}## vs. ##P## plot? [/QUOTE]
