"ST" is a Special Trailer tire. As in ST235/85 R 16.
ST - tire type. In this case Special Trailer. As opposed to "LT" Light Truck or "P" Passenger.
235 - tread width in MM.
85 - Aspect ratio. Sidewall height compared to tread width as a percentage.
R - Radial construction.
16 - wheel diameter.
Others will say differently, but after fighting defects in ST tires for six years (long ago) I switched to U.S. made LT tires and have had no problems since. (LT245/75R16)
IMHO almost all ST tires are made overseas (in the far east) where quality control is less than outstanding. DOT does not require any excess capacity beyond the load rating on the sidewall for ST design and the max speed rating is 65mph.
LT tires have heavier construction; safety factor above weight limit; higher speed rating; and a MUCH better reputation in RV service.
Let the rebuttal begin!
