As for not pushing someone in high gear, you never really know when you're going to get defended against, and not be practiced enough to downshift before the pushing begins.
To my understanding, that shouldn't matter. Friction (which determines your traction) does not really change based on surface area. There was a discussion about this in the Technical Discussion forum a few weeks ago. I think the linatex has a higher coefficient of friction (compared to the rubber gum or blue nitrile), which would result in a slightly higher available friction force, which would result in being able to push somewhat stronger. However, I don't think that the added torque from the third motor would really make a difference, as with the gear ratio already in place, your maximal torque would already be well above the maximal traction you can get.
