Why do some Busch teams just 'start and park'

There is a fibre imbedded in the rubber that carries information like a microchip. It can be scanned to identify to which team it was assigned

I believe they put the car numbers on the wheels. I'm not sure if it's the teams, Goodyear, or NASCAR doing that, but if it's not the teams, then I'm not sure it's legal.

NASCAR stopped letting teams buy tires when they decided that tires could be used as leverage in testing.

Goodyear's not happy at all with that rule. It didn't stop testing, it just sent their tire business to Hoosier, BFG, etc.

Plus teams still have HUGE volumes of old goodyears that have never been used

How good can they be after 2-3 years of sitting around?

Tires have a 7 year shelf life.

Which is why I get worried when the Busch Series threatens to use those 10-year-old rain tires.

That's illegal. Teams only get six sets from Goodyear from the time they check into the door until the end of the race. You cannot get a "start and park" team's tires. You must return all tires once you are out of the race.

I believe you're probably right. I knew that the teams only get 2 sets of practice tires and a set of qualifying tires before qualifying and NASCAR does check to see what is on the cars before the go out onto the track, every time. S & P teams used to used some older tires from their primary team but I guess not now. So an S&P team would have to buy 2 sets of tires in a weekend-one to practice on and one to qualify and start the race on. My bad.
