    24 hour distance record on motorcycle shattered

    This guy averaged over 100mph for 24 hours, pretty impressive! My only question is why did he need a new set of tires half way through?

    24-hour motorcycle distance record absolutely smashed in Italy

    LONG list of previous bikes not listed here.

    Because the original tires wore out?

      Not knowing anything much about tire wear, really. I googled it - Higher driving speeds cause more heat to build up in the rubber, breaking down the tire more quickly than at slower speeds​.

      So, at sustained speeds of over 100 MPH would, I think, wear the tire much quicker than normal.

            Yup, higher speeds wear out tires a LOT faster. Harder braking and acceleration do as well. Plus, all the wear was on one narrow stripe of the tire.

            Also, sometimes OEM tires are a special variant that doesn't last as long. Not sure if that applies here.

              Rubber has come a long long way. On the ancient cars the solid rubber tires would melt at max speed. 9mph michelins no less.

                Tire wear is proportional to load applied parallel to the contact patch. More load (braking, cornering, acceleration) = higher wear rate in those axis. The aerodynamic drag of a moving object (like a motorcycle) increases as the square of its velocity. So, doubling the speed requires 4 x the force driving through the contact patch. Flat out in a straight line the load on the tread pushing against the air is a big number and the tire wears out due to the increased speed at which the tread is being abraded on the road surface.

                    Yup. A wise fella told me when I was a kid, that tires that don't wear, aren't doing any work.
