During the "test K1 + K2" (see other post) I started mulling over what features should have a rubber based on usage, beyond the publicity of the case and advice (more or less interested) of your tire .
do not know if you've ever: choose the latest model of rubber "sport-touring" X reviewed by the magazine and go to the tire shop to order it, usually makes you "but made a nice soft rubber grip that does not which has the !, then you propose the latest gem soft bi-compound with silica, and he makes you "for heaven's sake, those are for the track, are very hard." So!?
the end I tried to rationalize the distinguishing between what behavior in steady and cold. Evidently, the parameters are different: it is said that a compound, a regime that is soft, go necessarily in temperature before a hard (do not know if it can depend on chemical composition, carving, thickness, etc.), that the thermal inertia of rubber and the equilibrium temperature are independent variables.
If so, however, should reconsider the classical division Racing / Sport Touring / Touring, and to consider all combinations of these two parameters, namely:
- Racing: slow and soft (should be warmed beforehand)
- Sport: Fast and hard (can be used soon, but should be stressed to keep them in temperature)
- Sport Touring: fast and smooth (go lower temperature stress of Sport)
- Touring: slow and tough (not stress or go to the limit, nor cold)
That then this to have a practical sense is another speech ....
