My trucks happy zone seems to be between 65 and 67 MPH....that's where I can get it to occasionally drop down to 8th gear.

The local tire rep said the new 17 inch ones were "R" along with the info on Amazon.

Like the email said the ones without the "ST Radial trailer tires, without a service description" (without letter code) are lower speed ratings. If you tire isn't displaying the "Q"(or some other letter speed rating) it is rate to the lower limits. Until mid 2015 ST did not display any speed codes but do to new import rules in mid 2015 they now have speed ratings.

Here is a thread where I ask about the new speed ratings. Speed Rating on ST tires.

Too Slow is Dangerous

In graduate school for Transportation Engineering, they taught us that speed differential causes accidents. If everyone on a highway is going almost the same speed, then there are many less accidents. You'll notice semi-trucks are involved in lots of accidents, and also cause accidents. With a 10,000 lb truck, and a 4500 lb trailer, I'm not worried about driving the speed limit. I do get better mileage at 65, but I drive the speed limit on the interstate.

Refuse to buy tires that aren't rated to at least 81mph. sells Taskmaster tires with that rating. They don't seem to know that, but when you get the tires the rating on the side tells the story. I've read that soon all trailer tires will be rated for 81 mph. About time.

I tow at whatever speed the semi's are running in the slow lane. In Michigan if you tow at less than 65 they will be passing you. I will admit that I hate running behind a semi truck so I usually will pass them and just try to stay away. I really hate the 3 or more lane expressways when the semi's are in the 2nd or 3rd lanes passing you.

Depends on the traffic or if the cops are out . Have towed up to 85 . Just got to be confident in your set up and let it roll.
