Very accurate - as in it's been tested and proven many times ... In fact RoadRacing World did a pretty comprehensive test a couple years ago that was very interesting.

The best and fastest way to build heat into a tire - ANY tire (I'm talking the carcass, not just the outer layer of rubber) is to flex the caucus through either compression or extension.
Now on a Motorcycle, "weaving" doesn't flex the carcass much, if any, especially at lower speeds.  but Heavy braking and acceleration do.  Which is almost the opposite of a car tire in which because of the shape of the tire, suspension design and weight of the car - weaving flexes the sidewall putting more heat into the tire.

that is how it is, wgtt. the ideea is that tires are heated mostly by the flex of the tire, and in a much smaller ammount due to friction. you must have flexed an aluminim wire and noticed that it gets -really- hot. when braking/accelerating fast, weight transfers to front/back, and tires flex due to this, thus, they heat up. doing burnouts also won't help very much. tires don't heat up fast enough, and you waste a lot of thread, especially with narrow tires. of course, best way to heat them is with the electric tire warmers. they also have the advantage of keeping the tires warm between races, so with race-only tires, you don't loose a heat cycle every time you stop for fueling/a drink/break. as i think you know, race tires have a given number of heat cycles before they start loosing their grip (the oils that keep them soft seeps out and they harden, behaving like a very old tire)

darn it, didn't see jason replied on the next page :P
