Here is a picture of how the speed rating is displayed on this particular ST tire. Even though the tire service description is not the official weight description for LT & ST tires they are still allowed to be on the sidewalls for reference purposes. The letter "L" behind the 113/108L is for a 75 MPH tire.

No such number/letter combo on my tires. I've not been able to find anything on these tires that resembles the speed ratings that I've seen on other tires during my research. I can find all other information except that. It's just ST225/75/R15 followed by H178 and that's it. So I think I just have to assume that they are rated for 65 mph.
