. How do Hoosier compounds compare to other manufacturers?

  

Hoosier
Compound

Cold
Durometer

Cross
Reference

 
   D10 35 Burris SS11  
   D20 42 Burris SS22  
   D30 48 Burris SS33  
   D40 60 Burris SS44  
   D50 64 Burris SS55  
   A40 53 Dunlop DBS/Firestone YFA  
   A50* 56 Firestone YFF  
   A55 55 Firestone YGF  
*The A50 compound will eventually be phased out and replaced by the new A55 compound in the 35.0/7.1-6 & 35.0/8.1-6 tire sizes.
"D" compounds are designed for dirt racing.
"A" numbered compounds are designed for asphalt racing.
Both types of compounds can be used for indoor racing as needed.   
  
6.   How are the Hoosier Kart & Quarter Midget tires sized?
The kart and quarter midget tire nomenclature is defined as follows: 
Circumference/Tread Width - Bead Diameter Size. Take for example a 35/7.1-6 size tire. The "35" is the circumference of the tire, the "7.1" is the tread width, and the "6" is the bead diameter size. All of these measurements are in inches and are measured on the recommended wheel width. To view each tire size and their specifications, click on the section marked "Specs" located under the Kart & Quarter Midget section of the Hoosier Tire website.
