I would say the tires were there for the mud from the water runoff. There was no where else it could go. Not having those there would have led to more cars getting torn up because guys getting the LF in the mud and not being able to turn.
All the rain had to collect somewhere after removing the tarps. The helicopter was the best. Gotta give them an A+ for doing whatever it took to get that race in. They could have easily pulled the plug and didn't have to deal with getting a track back so that they could put the show on.
