Still haven't had a look at actual tire for where its made (keep forgetting ).
Checked out the tires and are stamped "made in USA" this the 205/75/15 size in a "D" rating.
The Micheline tire is rated as an all position tire so, cannot see why it would not suit the bill.
Yes the weight rating is lower than the ST but the ST 235/85/16 is IIRC a 3500lb tire. The axles are only 5000lb axles , so the XP Rib still has a good weight safety factor and is not going to blow at 70mph.

Have We Answered Your Question
(OP) Quiroule -
Has your initial question, Do you know of any North American-made tires that would cut it?" been satisfactorily answered yet? The thread seems to be somewhat out of alignment.
If so, let us know as we seem to be spinning our tires here.

"To maintain tire safety, purchase new tires that are the same size as the vehicle’s original tires".
I'm guessing this means that if Keystone puts tires on a trailer that are barely able to carry the trailers weight and of poor quality. You should continue to pay for trailer damage from their failures and not replace them with superior tires with better weight capacity. It should read " To maintain profits, we have used the minimum tire to meet government standards. We have not tested better tires on our trailers so we can not legally recommend them.
That's My opinion only and everyone should do what they see fit for the safety of their families and trailers. I was concerned with the capacity and quality of the tires on my trailer so I upgraded them. I no longer tow with white knuckles and sleep like a baby at night. Hope you all travel safely and have a great holiday season, Hank

Well stated, Hank. I had not been concerned with our Towmax tires (225-75-15D) Kept the pressure at 65psi and always towed below 65mph. The DW was helping with maintenance by applying some 303 to the tires when she noticed some significant checking on the sidewall of one tire. All the tires are date coded within two months in early 2011. We have put approx. 3500 miles on the trailer (add to that the trip from Oregon to the So. Cal. dealer. Our 15in wheels are designated 2830 lbs. Given that there aren't many tires available in our size we will probably have to settle for the ST maxxis. I would like to put michelins on but they unavailable in our size and E rated.

I upgraded my 22575R15 Towmax Ds on my 2830 rated keystone factory wheels to Maxxi 22575r15 Es. I am running the new Maxxis at 80psi with no problem and have much more confidence with this set up.

I have a set of Taskmasters on a small flat bed and they have been the trailer for over two years now and show no signs of dry rot in the sidewalls.

Some additional tire info. During my recent tire research efforts, I visited the Carlisle website. They are advertising an ST225-75R-15E tire. The lower left hand corner of the ad states "made in the U.S.A."
I have read in numerous posts on this and other forums that Carlisle ST tires are built in China. Carlisle's website, in fact, shows 2 or 3 plants in China. 
I guess this tire company can do this because they do, in fact, manufacture tires in the U.S. - just not all of their tires?
I guess I will have to agree with the other posts calling for the DOT or the NHTSA to get involved. Without the sharing of knowledge and experience on this forum, I would have thought that these tires were US made!
Thanks to all who contribute to the flow of info

That goes on to say: " or another size recommended by the manufacturer".
