I think this largely depends on the tire&#x27;s &quot;side surface&quot; as well.<p>For instance, my motorcycle&#x27;s tires are not race tires, but street tires. The bottom of the tire only goes up the &quot;side&quot; for a limited distance. If I lean too far the side of my tire no longer touches the ground<p>Also, the lean angle would have to be related to the foot peg size. My current foot peg is quite long--even for mild lean angles somestimes I can feel the road scratching on my boots and the foot peg.
