For those running ST tires (as opposed to LT tires)...they are rated at 60 mph max. That's what I do!
Hmmm... I always thought ST was 65mph max.
I tow around 65mph... sometime a bit above, like 67, but never more than that. My trailer weight is well within the capability of the trailer tires, and they are inflated properly. Haven't towed in the mid-USA, but had absolutely no problem towing down the east coast on I95 to Florida at 65mph, or up in Maine at 65mph.
When a friend first got his TT, he told me how well it towed above 70mph...! I told him to look at the tires of his TT, as they probably weren't rated for that.
After a few camping trips, he was complaining at how his Duramax got such poor fuel mileage towing. I mentioned he might want to try slowing down to 65... he scoffed at that. Later that year, I noticed him towing slower, at 65mph. He sheepishly admitted that I was right, and his fuel mileage jumped when he dropped from over 70mph to 65mph.
Having been in the fire department for awhile now, I have just seen too many accidents caused by 1) cell phone usage and 2) speeding, for me to do either one of those while towing (or driving in general).
