and optimum flaps are being used in most of the cases
Optimum flaps often requires higher takeoff speeds; therefore higher tyre speeds. Higher VR speeds than necessary increase the chances of tyre failure. High speed tyre failure on limiting runway length increase the chances of an over-run if the pilot decides for whatever the reason to abort the take of run. Especially as loss of braking efficiency will occur with tyre failure. No brainer for the safety conscious pilot especially if runway wet
