Ok- Just talked to Robby, and he has informed me that he had ZERO issues with the tires during the 2nd practice. He said he did a 20 lap run,no problems,car sucked up very well, and he is very excited about the Duel 150. Main objective, keep the car in 1 piece and he is taking a play it by ear strategy as far as his racing goes,so don't assume he is going straight to the back.So in conclusion,the tire issue he had during the first practice was NOT an issue during the 2nd practice,
