increased tyre wear?thats funny!
Can you confirm that you actually believe that such a turn will produce no tyre wear. If so I am astounded.
A sharp 90 degree turn WILL produce tyre wear on any type since the inside wheel will be rotated to some extent about its contact point and will scuff just like a car tyre when doing a low speed turn. On a bogey type there is also a substantial sideways force on the wheels as the bogey turns (Boeing officially recognise this). Perhaps an idea to check the technical details before you laugh.
