M/T Tires are compounded by size and application. The following points are general application suggestions. Mickey Thompson and First Choice Wheels and Tires are not responsible for misapplications.

To identify the compound of your current M/T ET Drag tires look at the serial number on the sidewall of the tire:

  • ST - Suggested for manual transmissions (medium compound)
  • W - Extra tread width (please note actual tread and section width on spec sheet)
  • S - Stiff sidewall construction aids in quicker reaction time due to less tire distortion. Also good in high horsepower applications and for heavy cars (Over 3,000 lbs)
  • C - Sport Compact
  • R - Radial Construction
  • * - Stiff Sidewall
  • High Growth Tire
