There is a mold-release compound that is basically a lube, but it's gone within a few miles of driving. For track tires, it's gone within a lap. First flying lap at temp is the fastest lap for most tires.I have no doubt there's some technical truth to that (although who knows what conditions that true under), I'll bet that's mostly legal ass-covering.
Most high performance tires are stickiest when new (assuming they're hot--which is true for any tire).
The 500-mile breakin is for extremely hard all-season compounds and/or just legal CYA.
