The steeper the track the more you wear the sides of the
tire. T-town is relatively flat. At Alpenrose the right
side of tires wear and the left side never does. The side
wear is very obvious and much more than you would see on
any road tire. If the tire label is on the right it will
generally be worn off quickly, something that you rarely
see on a road tire. The angle between the track and the
riding surface is more often higher than it is on the road.
In tight turns the tire may see a high lean angle briefly
on the road but on a steep track it will see a high lean
angle for much more time.
