Taxiing, in and of itself...
Taxiing, in and of itself, creates heat in the tires....thereby transferring heat to the wheels (because the tires are attached to the wheels)....and, with hot wheels, brakes become hotter....because, when applied, brakes touch the wheels.... You get the idea.
There was an accident several years ago....can't remember....I'm thinking it was out of LAX....because the guys were taxiing a long distance, at high speeds, not following SOP with regard to brake use during taxi. (Can't really remember the details, so if I'm wrong, I'm sorry.)
The faster you taxi, the hotter the tires, therefore the hotter the wheels, therefore the hotter the brakes. This also goes for the farther you taxi.
Planes were made to fly, not taxi.
Anyway, I'm thinking they had one or more tire failures during takeoff, rejected the takeoff (usually a bad idea, depending on the speed at which all this happens)....couldn't stop (because they had fewer tires/brakes to stop them).....anyway, another statistical RTO accident.
All because they were heavy, taxied too fast, taxied too far, rode the brakes, rejected the takeoff because of tire failure....all mistakes.
(Well, how heavy there were wasn't their fault, neither was the distance they had to taxi....but, the rest of the mess was.)
So, the Boeing chart is correct. Follow it. If you don't understand, ask your friendly training department. That's what they're there for.
Fly safe,
