Re: [ST] Tire break-in (was Battlax BT020 and the rain)

My experience with heat cycles in auto racing tires is that they make 
the rubber harder with each heat cycle; undesirable. Street tires are 
cured differently and are not changed by heat cycles.

 From Bridgestone's website:

Break-in Period

In order for your new tire(s) to provide optimum performance, tires 
should be ridden very cautiously for the first 100 miles in order for 
the tread surface to be ?Scuffed-In? and work properly. Directly after 
new tires are mounted, sudden acceleration, maximum braking and hard 
cornering must be avoided. This will allow the rider to adjust to the 
?Feel? and handling characteristics of the new tire and for the new tire 
to be ?Scuffed-In? correctly in order to achieve optimum grip level.

No mention of mold release compounds, but they have to be using 
something to promote release.
