National Staff Greg G. Posted November 27, 2011 National Staff Share Posted November 27, 2011 TECHNICAL BULLETIN (11-27-11): Beginning with the 2012 TT, PT, and ST seasons, the Hoosier 255/35-18 (A6 and R6) will be assessed points based on its actual 275mm size. This assessment will be for both modification points in Section I.a of the PT and TTA-TTF Rules, and for modification factors in the calculation of Adjusted Wt/Hp Ratio for TT, PT, and ST. (note: Under the current Rules in TT, PT, and ST, there is no functional change in the calculation of Adjusted Wt/HP Ratio. It will only become an issue if there are changes in the tire Modification Factor rules in the future.) Link to comment Share on other sites More sharing options...
