Also driving over the curbs at COTA can damage the tires too! I saw at least 3 other Pirelli slicks come apart that weekend on different GTR's. That's why I use Hoosier R7s. I didn't have any tire problems.
"Come apart" - literally?
I've only run Pirelli 305/690-19 DH & haven't had them come apart...curb hopping* at every opportunity. My fronts will cord first on outside of tire (@ -3.5*, slight toe-out), rears just inboard of center (@ -2.0*, slight toe-in).
*I would think that if you straddle curb in T8, but carry too much speed such that you're thrown back across curbing before apex, then the raised inside lip of the curbing would be pretty hard on the tire.
