I'm not saying that it isn't a trailer-specific tire - it is, and that's what the Goodyear website says. My point is that, unlike the Goodyear Marathon, it is labeled as an LT, not an ST, tire. The Marathon carries the ST prefix on the sizing label and is rated for 65 MPH, the G614 does not and, as you say, is rated for 75 MPH. I've had 2 sets of the 614s before I got rid of them after 2 tread separations and went to 17.5" Michelin XTAs.
