Off The Road - Rock Service Tires
E3/L3 - E4/L4 American Contractor® Rock Service

Look no further than Specialty Tires of America for these hard-to-find, high durability tires. Built with a heavy-duty carcass and a special compound for a cut resistant tread, these tires offer unparalleled protection on sharp rocks in quarry uses. A deeper in-tread depth also allows for superior traction in off road environments.

With the worldwide shortage of the E3/L3 - E4/L4 tires, Specialty Tires of America is your source to get the tires you need with a greatly reduced wait time.
