Load rating for bike tires.
I understand most tire failures to be heat related in the auto industry. Higher loads increase displaced tire and sidewall distortion causing heat accumulate... But this requires a lot of speed.
Why are there load bearing capacities on bike tires? Where does failure come from?
70psi in a wide city tire means a bike carrying 140 lbs would create a contact patch of only 1/2 inch each tire.
Seems it would be easy to handle almost 3-4x that load and contact only 2 square inches each.
Anyway....
