Every trailer tire will have a specific speed rating listed by the manufacturer. This can vary within the same tire size and design depending on the model and brand so there is not a general max speed recommendation for a 175/80D13 trailer tire. The speed rating will be listed right on the tire's sidewall. When there isn't a rating listed then the max speed is presumed to be 65 mph.

For an ST175/80D13 bias tire I recommend the Taskmaster # TTWTD17513C that features a speed rating of 81 mph (the highest we have available in this size) and a load capacity of 1,360 pounds at 50 psi.
