I admittedly have not paid much attention to my tire pressure - primarily because I just haven't understood HOW to know when to make adjustments. Guys talk about making 1 psi adjustments to dial in their tires, but honestly I think it's a stretch for a weekend trackday rider like me to notice such a subtle difference in the actual performance of the bike (was it the tire that made the difference in the lap time, or was it just me figuring out the track...). I gotta believe every performance tire was probably tested on a fancy test rig that determined at what TEMPERATURE (not pressure) it achieves its maximum grip. The job of the rider/crew is then to get the tire into that sweet spot, which would occur from a combination of the rider working the tire on track, and from flexing/deformation. This last part is where the rider has some control over the tire temperature - less pressure = more flex = more temp. The question becomes "how do you know when you're in that sweet spot???". You can INFER the temp by looking at the wear, or by feeling it, or even by estimating the temperature by how much the pressure went up (seems flawed). But wouldn't the best method be to actually MEASURE it? I realize that it requires a special pyrometer but isn't that the right way to do it? And if so, do the tire companies publish their intended/optimum temperature ranges? I haven't found anyone that does. Is it because they don't trust non professionals to do it correctly, or is there something proprietary about the info? Or is there something inherently dangerous about it?
