32o driver,
Flight crew training manual will give you such info about NOSE wheel tyre wear during fast taxi...(B737).
Concerning the line up thing,here is the copied info taken from boeing safety guide:
2.3.6.3 Runway Lineup
Positioning the aircraft on the runway in
preparation for takeoff is an important element
in maximizing the amount of pavement available
for a possible RTO maneuver. Correction to the
available runway length can be made to the
takeoff analysis on those runways where it
is not possible to position the airplane at the
beginning of the published distance.
Correct runway lineup technique should always
be practiced regardless of whether or not there
is excess runway available. Even if an allowance
has been made, it is up to the crew operating
the flight to align the airplane on the runway
using the shortest possible distance. If they
can do it in a shorter distance than taken into
account by their company, then there is that
much extra margin for the takeoff.'
As i said i let the wear/tear for the airline to check, Im concerned about my flight,my passengers on the particular day.

On a 737/800-900, a 9 kts entry followed by a 6-7 knots turn will get you lined up without thrust.10 kts into the turn is bit too fast i think.
