Everyone has valid points here an the answers are even tougher.I know tires r hard to police.I can say we have had little trouble with the tires.I can understand teams from hours away trying to get tires..I would not want to wait an mount tires on race day.
How ever i wouldnt want to go back an buy new for over 500 a set.I know some of the tracks we run at have tech tools all big10 has to do is ask them for help.Whistler, Tube, check cam lift.an so on...I know the tires big10 r using r supposed to be from lead lap cars an 100laps or so on them ...an then turned in an then we get them...How do we really know that,well we dont. The 1070s maybe a good choice but whos gona control them 100 percent.Whos car did they come from were they treated?I honestly think a chemist could come up with a 1 drop test on tire for any softner....Cause u sure cant tell a racer is tire smells funny....My 2cents fire away my friends.....
