Although it's nearing the end of winter and becoming perhaps less than an issue I'm still interested in this. I get that riding along, the friction between the road and the tyre causes it to heat up, and thats all well and good. But I've seen it written that a professional rider is able to get a tyre running a lot hotter than your average rider, what causes this? Is it harder braking? Carrying more speed overall? Are there anything a rider can do to cause a tyre to heat up before reaching some twisties? Enlighten me.
