The tread. Normally, the tread wraps around to the sidewall abot 2-3 inches, these tires show the tread riding only on top of the centre belt. If they were to wrap the tread like a conventional tire, it would separate from flexing. Those are multi-compound tires, the centre belt under the tread is heavy thick steel weave, which also makes the tread stick out higher in the centre.
