Both of your tires are "right". The specs that I attached to message #14 are TIRE specs.
The specs you are quoting as 11.2x24 are for the WHEEL that tire goes ojn. .
All 11.2 x 24 tires will have those same exact measurements. They are industry wide standard measurements for the size of wheel that tire was made to be mounted on.
In inches, the 11.2 measurement is the distance between the beads - i.e. the inner mounting surface of the wheel. The 24" is the wheel diameter measured either at the nominal or the outer edge of the bead mounting surface....I'm not sure which is used... probably the outer edge.
