It seems NHRA heard a rumor that some of the Pro Stock cars may have been using wheels an inch or so wider than permitted, so an effort was made to do some spot measuring.  In more than one instance, when inspectors arrived in the pits and teams were hard at work they announced their intentions, and said they’d return the next day!  Like someone who might have been using illegal wheels couldn’t have switched them overnight?  And people wonder why we write, “What were they thinking?” more than a half dozen times each year.
