I spoke w/ Carlisle. The 15" RH Radials were indeed rated at 87mph, but due to our govt placing a tariff of 15" tires rated at 87mph they have been lowered to an 81mph speed rating. 16" are rated for 75mph, I think he said the 14" were 87mph but not sure if the rating was lowered like the 15" tires due to the tariff.
I have almost 3k miles on my set that I purchased and installed in late February of this year. I do not go over 65 and wouldn't recommend just by what they post on their website.

"How fast can I travel on Carlisle trailer tires?"
In the past, most trailer tires were rated at 62 or 65 mph. Today, some of our tires are "rated" (speed symbols) at 87 mph (N), some at 75 mph (L), some at 65 mph (J: ST tires) and some at 62 mph (J: non-metric tires).
Please remember that speed ratings are test speeds and not recommended driving speeds. The ratings apply only to the tire itself, and not a particular vehicle. The speed rating does not mean that the vehicle can be safely operated at the tire's rated speed.
We recommend driving no more than 60 mph when towing a trailer.Please always drive at a safe speed and abide by the posted speed limit.
Glad to hear you are happy with the Carlisles so far. While I didn't have that many miles on either set I had when we sold the trailer, I was happy as well. They needed very little air when it was trip time, even after sitting all winter.
As for the speed rating, to me it is peace of mind. The same as running an D rated tire in place of a C, or an E rated in place of a D, due to the extra "reserve capacity" or "reserve speed rating". This is the main reason I plan on replacing our stock tires in the Spring stepping up to E rated tires for the higher weight rating. But knowing I also have a reserve in the speed rating, priceless! Lol Sorry, couldn't resist!
I usually tow at about 65- maybe 68ish, but at times when passing someone due to traffic coming up behind, or on a downhill speed may creep up a little more.
I am sure a lot of the suggested speed is the lawyers covering the company's behind. I could see it now: the "crazy driver" - "Well..... Carlisle stated the tires are rated for "xx speed", not sure why I lost control of my 8k lb trailer....."
Just because your truck can tow at 80mph or so because you have the power, can you control it?
Safe travels everyone!!!
