The 2013 Right rear tire is the same tire that was used in 2012 The Hoosier 106-16 MEDIUM tire. A hard tire will still be available as well.
The great news is Hoosier has offered SOD lower pricing for 2013!
Right and Left rears will be $198 fronts will be $165
Tires are now available at Hoosier Midwest if you would like to get some tires.
The 2013 rules will be posted on the SOD website this weekend, there are very few changes or updates so there is no need to worry about major changes to the cars.
NOTE: Typo on the tire from the first post corrected from 106-15 to 106-16
