But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government.
Yep, you sipe a slick for a drying track normally.

I'm not sure if you get what we've got from experience.
Radials don't produce the heat of old bias ply tires that we used to race on. A radial can have situations where they can't get enough heat into them even on a completely dry track and even with tire warmers.
One can cut grooves in the surface to produce heat by reducing the contact patch just a small amount, forcing the available contact patch to work harder...developing more heat.
I've siped lots of tires on sprint cars, I know what it's about. Also shaved them, shorter blocks generate less heat due to less squirm.
On bikes I've seen it done normally for drying tracks, but of course it can be done just if it's cold...or the surface is cool/damp like Laguna often is this time of year.
Also, I would guess most of the heat is generated by the edges impacting the ground, and a loss of rigidity in the tire allowing it to squirm, not the small increase in load across the blocks. You do get competing effects here with the air also cooling the channel.
