Douglas is the trademark for a line of tires owned by the Goodyear Tire and Rubber Company, which manufactures the line and sells them exclusively through Walmart. Goodyear registered the name in 1992[1] through its subsidiary Kelly Springfield Tire Company.
The actual location [2] of manufacture of a Douglas tire can be determined through the first two characters following the "DOT" of the DOT code molded into the sidewall and consulting the NHTSA Manufacturers Information Database.
