I can't confirm or deny such a theory but I do find it interesting. I can tell you that in Nascars quest in making their product more exciting through tire wear has ended Newmans and many others race day in a hurry. Matter of fact, it has ruined many drivers chances at "The Chase" as well!
The tire theory if you think about it may be the little secret that hasn't been payed much attention to as maybe should be? I know, you have to deal with what ever tire is brought to each race track. There is no "tire menu!"
Then throw in all those famous I won't wreck you but I will "rub" your race car and create a tire problem for YOU! Oh yes, every driver knows this trick very well! Newman has been the recipient of this common practice many times.....trust me!
Drivers and anyone related to NASCAR in general have to be very "politically" correct in NOT disrespecting their tire makers or their tire products.(Tony) BUT YOU KNOW.........all race teams would rather have a kick butt tire at every track and just race!
Purposely making a tire "weak" for entertainment purposed is totally ignorant in my opinion. And if your watching NASCAR only to see cars wrecking.......find another sport to follow please!
