A secondary advantage is that the surface of the mold remains clean enough not to require refurbishing through at least 20% more curing cycles than is possible with a sidewall conventional sidewall compound without the specified tackifier and t-alkanolamine. Multiple washing of the sidewalls during a month of using the tire, fails to diminish the gloss substantially.
