Having run LTX for 12 years (indoor storage, no cracks, no issues no rebalancing) I went with Cooper HT3 as replacements 3 years ago. Driven from midwest across the Rockies a few times as a “road test”. I highly recommend them. The LTX and HT3 both have a similar tread design in the center blocks but the Michelins (old and new) have separate blocks on the inner and outside rows. The Coopers have more of a continuous rib in those areas. I find slightly better linear tracking with Coopers during truck push and crosswinds as there are no separate “N” shaped blocks to “crab”. Ride comfort and balance about the same, I don’t think you could tell in a blind test. Visually, I would think the Michelin would vent out deep water better, but hydroplaning isn’t much issue with our weight anyway. I have been stuck on wet grass on flat with LTX (GMCMI Berrien), but did rock out. I have been stuck in the wet grass with HT3 but with nose high backing down to my home septic on wet grass so not a fair comparison. The new Michelin pattern looks like they went to a finer pattern for light snow/ice/frost conditions, just my guess. The big difference is price. I payed around $120 a tire for Coopers on sale. So the money you save is substantial on a smooth great riding tire made in USA. I’d buy the HT3s again without a doubt. I run 63 rears and 65 fronts. I have not been weighed. I might be able to tweak more exactly if I knew that.

My coach came with LTX and I too need to change my tires mainly due to weather cracking. I probably wont buy them again mainly because of price BUT i will say this about them....we put 800 miles on these weathered/ badly cracked tires last summer when we drove it home after purchase and i had no worries in my mind that they would fail us because of the Michelin quality.
So if your going to drive alot, which we dont because of winter here, i wouldnt be to quick to discount them.
The Coopers HT3 would also be ok i guess....Michelin owns Cooper so the tread pattern similarities mentioned. JmHO.

How about these Nokian tires :
Nokian Rotiiva HT All Season Radial Tire-225/75R16 112S
on Amazon for $115 almost half the Michelins
I've had them on mine for 4 years and am perfectly satisfied.

Minimum Hydroplaning speed for a given tire is 9 times the square root of the tire pressure.
That’s a minimum number, and tread design plays a significant role in increasing that number.
Commercial tires tend to sacrifice ride quality for high pressure and safety.
60 psi = 69 mph
70 psi = 75 mph
80 psi = 80 mph
90 psi = 85 mph
It’s one of those facts they beat into your head when you get a pilots license, and the light bulb goes off because you realize why the 18 wheeler is blowing by you in the rain, and it has 110 psi tires…..

I wondered about that when I saw the posting. They use to be headquartered in Findlay, Ohio I believe. I know I went by the HQ once a long time ago. After that posting, I thought maybe they got bought out like Firestone - Bridgestone or Goodrich - Michelin - Uniroyal

There are 2 "versions" of the Cross Climates: A symmetrical tread and a directional tread. If it's listed as 90psi max pressure, you are looking at the symmetrical tread Cross Climates with a service description of 115/112R. The directionals have a service description of 120/120R, but only take 83 psi.... I guess the directionals must have a stronger case, as they are rated to carry more load at a lower pressure.... 3195 at 83 vs 2680 at 90 psi, for our 225/75/16 size....

As an aside, neither my pilots license - '68 nor G.I. license - '70 mentioned that formula or any other for hydroplaning. If memory serves, you were taught to land gently and slow equally gently on a wet runway to avoid hydroplaning.
A lot has changed over the decades, most if it in my opinion not in the student's best interest. No more spin recognition, and stalls are only flown to the onset of buffeting. I was taking a checkride at the Keesler Aero Club some years ago in a Skyhawk and the kid who was the instructor called for a departure stall. I banked it and cobbed the engine and hauled back on the yoke, and when it started bucking and rattling kept pulling and he's like "What are you DOING???" So I rolled it level and got out of full power and said you told me to stall it. Do you want me to or not? That's when I found out about the change. Now it's my contention that a pilot who has never truly stalled the airplane in different configurations, and who has never seen a spin is a ticking time bomb who will get in a tight one day and kill himself from ignorance.

a litle off topic, but... Years ago my instructor decided the day my wife came along for the ride was a good day to practice stalls. Like full drop and catch stalls. I was having a good ol' time until we hear this weak desperate voice from the back: "I'm gonna be sick." OOPS, forgot she was there.

Hydroplaning speed.........9 times the square root of the tire pressure.
That is what they taught at B-52 flight training.

And when I was in F-101B's at the time hydroplaning first became a "thing"
in about 1963-4.

Follow-up 2020-05-12.
Since creating this post I wanted to give you all an update.
I purchased the Michelin Agilis Cross Climate 225-75-R16 Grade E tires from Discount Tire.
The price was fair. I have owned several varieties of Michelin tires in the past and have been more than satisfied with their longevity and service. They have stood behind what they sell. The fact that this is a new tire line (2019) to replace the LTX tires so common on the GMC's was another factor. This way if I do have an issue with these tires in the future, I hopefully will be more likely to find them available as a direct replacement rather than an obsolete tire. Another reason I went with Discount Tire due to their large service base. Based upon the Michelin marketing material with improved stopping distance compared to the competition was also a consideration as well as the beefed up side walls.
As for driving. I have just completed putting about 1,000 miles on them on a variety of road surfaces. 500 miles of this was in a one-day 11.5 hour trek. This includes smooth highways to bumpy and pitted highways. Overall I am satisfied that they perform as delivered. Quiet on the smooth surfaces with good tracking. As for bad roads they did not change materially different than the Goodrich Commercial T/A's they replaced after 10 years of use and nominal tread wear.
I am satisfied with the purchase.
