I need 1 or 2 Firestone or Bridgestone 24X8.5-12 new or used. If not, anyone running any other substitutes that meet the 4wd ratio with 13.6-16 rear tires ?
You won't find that tire, its not made any longer. A excellent substitude is the Carlisle Turf Master 24 x 9.5-12.00. Its the same height so your rolling ratios will stay the same.
