    Being in the US I’m not familiar with the JAA’s advice about taxi speeds. But based on standard practices here, slower taxi speeds reduce tire wear and brake pad wear. If you’re going fast and have to stop quickly, that friction between the tire and the surface slowly grinds down the tire, as well as brake friction wearing away at the brake pads, compared to slow taxi speeds which require little to no braking. Going around a curve will also have more tire wear at higher taxi speeds because of the horizontal shear forces of the friction helping the airplane turn. It’s the same as with car tires.

    I’m not sure how taxi speed affects the forces required to fight a crosswind and how that translates to tire wear, but for strong winds a slow taxi speed is always best practice.
