-Spoke briefly to Robby, and the problem was a left front hub,burned the bearings right out.NOT a tire problem.What caused the problem,will NOT be a issue on Sunday.The tires looked good after each pitstop,and RG is very happy with the pitcrew.2 new tire changers. Said car drove great,sucked up awesome, and when it is time to go on Sunday, it will be time to go to the front.Also, Robby made it clear, he did NOT touch the #2.Things look good for Sunday,and again, the problem with the left front hub has been rectified and no worries at all.
