Tire shine question

[13BlackGT]

Is it ok to use products like ArmorAll tire foam on the sidewalls of drag radials? I ask because my last ones developed small cracks at only one year old with about 1000 miles and 15 passes.

Just got email back from Mickey Thompson, they are going to warranty my old ones

Ive always" shined" them. No problems.
