What is tire doping in dirt racing? Is there a chemical that can't be detected?

It's been well circulated about special Hoosier ump tires over the years to certain teams so no different. Tire rules can work if have fair rules and for that you need specs so anyone building a tire can compete. I'm all for different manufacturers but "same" tire.

To the hard tire comments, are you sure they dint work? I look at imca mod rules and the racing good but they say they're bricks. I haven't full clue as imca isn't my area but sure do like some things I see over time from imca divisions

Fortunately tire prep is mostly legal and encouraged in RC racing. This should be the same in big boy car racing as well.
