This week the Goodyear Knoxville Nationals coming up;do you think the trick tires for WoO regulars will manifest themselves or will it be same for all?How about ten or twelve years ago when Goodyears 30's won it.;

Supposedly, all Speedweek tires will have the 50th Anniversary logo molded into them.
That doesn't necessarily mean someone won't tinker with them though.

If they don't check them, I sure guys will be creating there own tire hardness with softeners. Many of the average fans have no clue about it but it is very popular at your weekly tracks.
