How fast do you tow?

That's about it 2 lane good road 65 ish, interstate 70. If I'm in a hurry I'll push it 75-80, but don't like to.

Look at your trailer tires, I bet they have a speed rating lower than 80MPH. I donít go faster than 67. Best mileage and at 60+ yrs old I really donít care about being first. If Iím on a two lane road I watch my mirrors and will pull over when safe if I see more than 5 cars behind me.

It's inappropriate to pass judgment on someone I don't know and have never met, so I'm not "passing judgment" in this post, but a few things strike me as "glaring problems"

Speed rating on ST tires, barely adequate safety margins on ST tire weight capacities, "sub-par breaking system" on most RV trailers, 14 year old tow vehicle (typical mechanical wear/metal fatigue from being used for 14 years) to name a few. Towing at speeds in excess of "around 65MPH" places not only those in the tow vehicle in potential jeopardy, it does the same those who unknowingly share the road as well......

I do 100 KPH (62 MPH) on Carlisle HD 225R75/15 speed rated at 81 MPH. Legal speeds on most highways in our area is 55- 60 MPH. Not in a hurry.

Here's the deal to me; pulling a large RV at 80mph is not only dangerous, it's derelict and is a huge danger - for anyone. It's hard enough to control them at 65 mph, but to pull one at that speed with a 14 year old ( it will not be like new OR have the modern braking, sway etc. controls) is just "off the charts". Am I passing judgement? Probably. Is towing a large trailer at 80mph glaringly "dangerous" (polite)...absolutely.

Well I will tend to go with the flow to point, two lane state highway 55 to 65, interstate 65 to 70. Seeing how the LT tires on the 5er are speed rated to 106 that is not a worry. Package handles, and stops well I don’t see an issue. Not likely to do 80 as I like decent fuel mileage.

The sweet spot on my Duramax for towing is right st 1700 rpm which is approximately 68 mph. I have more than enough truck, disc brakes on both 5er & truck, H rated Sailun tires on the 5er & at that speed I'm not impeding every other vehicle on the highway.

I two a 9200 lb 5er with my Ram 2500. I'd run 70+ if I didn't like the fact that I get terrible mpg's at anything over 60 mph. My setup is rock solid and good for 80 mph if needed. My tires are rated at 81 mph. I would never tow a TT over 60-65, but I'd sure to a 5er over 65 mph. 5er's are way way more stable. Now stopping is no better for either so I only tow fast when out in the open by my self.
