Maximum tow speed for 6500 lbs Toy Hauler with two axles

I personally do not know, nor have been on any roads in Wa st, that have a towing, truck, vehicle over 10K gvw, not matter the type or style that is over 60 mph. Solo cars have upwards of 70 mph.......

I personally like to do in the 60-63 range. That is me...... yes I have done faster like South Dakota, eastern Montana where it is repetitively flat, wind behind me etc. Sure used the fuel!

I seem to recall Utah and Nevada were the states that set speed limits when there was none before.

speed limits beyond 65 for non comercial towing:
MT, WA many sections, OR some sections are 70, ID, UT, I could go on.
OR truck speed limit only applies to (a) comercial operators or (b) non comercial towing with a non passenger vehicle. E.G. converted semi.

MT, WA, ID, all have truck limits above 65mph on various roads.

IIRC from my last trip MT is 80 cars, 75 trucks on many interstate sections. other interstate sections are 75/70.

My Carisle tires are rated for 75 or 85mph. I am comfortable with my setup at 68-72mph. If your WDH is set up well and your TT tires are rated appropriately, then 75mph seems reasonable under ideal conditions with the flow of traffic or light traffic.

MY China bombs are clearly marked 75 mph maximum speed. The old "All ST tires are 65 mph limited" is no longer true.
That said, if I can get going and stay at 60-65 mph with the wind resistance and my current TV, I am literally a happy camper. Actually, when towing I'd even have to argue with the Red Rocker, I CAN drive 55!
There are a few ST tires rated at over 80mph. IIRC, Goodyear Endurance are rated ar 87MPH and there was another rated at 81 or 82, Carlisle I think.
Lots of variables.

I tow 75 if conditions and the road permits. Lots of wide open space out west. Just check your speed rating on your tires.

Your speed is your responsibility. If your rig is not violating any safety features I see no reason for not traveling at the allowed maximum speed of the state you're traveling in. However, you should insure that your trailer tires have a speed letter or other speed restriction identification on the tire sidewalls that will allow them to safely travel above 65 MPH. Almost all of them have some form of speed limiter on their sidewalls. In the speed lettering system "L" is for 75 MPH. The only current trailer tire manufacturer that I know of without a letter "L" or higher is Maxxis.

That's for radial tires. Bias ply may be 65 MPH or less. Carlisle letters bias ply with a "J", 62 MPH.

RVIA no longer recommends bias ply tires for any trailer fitments above 13" OD.

If you've upgraded your ST tires to LT to avoid the 65 mph speed limit of ST tires that would be a good first step. If you vehicle is capable of the weight your hauling/pulling and the conditions are right I don't have a problem towing at 70 or 75 mph. If the speed limit of the road your on is that high it's safer in my opinion than being a rolling road block at 10 mph under the speed limit.

I can cruise at 80 with my setup if I want to. However I set the cruise at 72. That’s if the limit is 70. My tires are rated at 80mph. Going out west on the uncontested imtersttate I have no problem cruisin along at 75. It all depends on the hwy and conditions.

I like to crusie around 70 to 72 mph, if the road conditions permit.
