This is all I've been able to find so far on testing:

"Goodyear has scheduled a NASCAR tire test at IMS for April 22-23"

Notes: This is the first time Goodyear has brought this tire set-up to Indianapolis Motor Speedway . . . this combination of left- and right-side codes was selected after a tire test with Kurt Busch, Dale Earnhardt Jr. and Brian Vickers at the Speedway on April 22-23 . . . the chief tire issue expected this weekend is expected early in practice as teams put down a layer of rubber on the abrasive racing surface . . . as typically seen on the grooved racing surface at Indianapolis, tire wear is expected to be high during the early practice sessions . . . in anticipation of this extreme tire wear situation, teams will have two extra sets of tires for practice and qualifying this weekend (up to eight sets) . . . IMS is the only track at which Sprint Cup teams will run this particular tire set-up this season . . . as on all NASCAR’s ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Indianapolis . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

Last night, I spoke with friends who went to the race. They said all of the fans were just royally pissed off the entire time about all of the competition cautions. They said there were a lot of people that left early (explains the gaps in the grandstands we started seeing in the last 40 or 50 laps).

The most telling thing about all of this is that Johnson's tire blew during his little victory burnout. My friends that went said it sounded like a bomb going off.
