So you got some things right.... specifically the things you said were incorrect.
Unfortunately, most of the things you then went on to say were the truth are myths as well...
First off, DO NOT put warmers on street tyres.
You will burn the crap out of them and cause all of the oils that are in the rubber to come out, severely reducing the life of the tyre.
Warmers are for track tyres only. No if buts or maybes about it. And yep, around the 160 mark is correct, but it changes significantly for different tyres and riders.
Next, warming of the tyres has almost nothing to do with surface friction.
Doesn't matter if it's the result of swerving from side to side or braking and accelerating it doesn't make squat all of a difference to the heat of the tyre.
The heating of the tyre is caused by deformation of the tyre carcase. To be more specific, that deformation causes internal friction within the structure of the tyre generating heat. Imagine the rubber of the tyre as a whole bunch of individual pieces, as you accelerate, brake and go around corners you cause those pieces to move in relation to each other, friction happens between them.
The reason accelerating and braking does a better job of heating the tyres is because 99% of us mere mortals can't achieve the same sort of deformation by cornering as we can achieve by getting on the throttle or the brakes... it takes the likes of a GP rider and balls big enough to make en elephant jealous to get the same result by cornering.
Next, car drivers (be it stock, F1 or any other) do warm their tyres by swerving from side to side. Next thing is why? Simply because what they are driving has mass
. A car thrown from side to side puts a massive load on the outside tyres causing a significant deformation, heating them up (again, it has almost nothing to do with surface friction)
. It's much harder to achieve the same result by accelerating and braking in a car as the weight transfer from front to back isn't as significant as side to side, although it can still be extreme when they aren't stuck behind a pace car.
Crap on the tyre (in the case of race bikes and cars)...
Swerving from side to side doesn't remove squat. The low speeds and high temps that are reducing will in fact do nothing to remove stuff, and may cause it to actually sink further into the tyre as a result of it being between the tyre and the ground and the tyre cooling and getting harder. That stuff is being vulcanised into the surface. What removes the crap is getting it hot by going at race pace and the sheer centripetal forces in play at +250 km/hr. The softer tyre means stuff isn't stuck to it as well and gets thrown of easier.
On the other hand, when it comes to road tyres that aren't melting, swerving can remove stuff as the abrasive action between the pavement and the tyre will knock it loose.
New tyres are slippery
. Always have been and likely will remain so for a good bit longer yet. The thing that makes them slippery is the mould release compound on the surface of the tyre, it's designed to make the rubber slippery so that it will come out of the mould easier and it doesn't magically become sticky once it leaves the mould. There have however been significant improvements over the years that mean it takes a lot less time for it to wear off the surface of the tyre. Don't absolutely thrash your bike till the shine is gone... depending on how you ride, that could be 2 miles or 200. Having said that, you don't need to baby it either, tyres are still pretty good even with mould release on them (hence if you are aggressive and good enough, it will come off real quick). And yep, you are correct in that heat plays a big part in how fast this actually happens.
Hope that clears a few things up.
