Very few coach owners "rely on where the rubber meets the road to put food on the table".
IMO any coach owner who thinks "outside of the box" about his tire pressure is making a mistake.

so should I be changing tire pressure loaded vs empty?, It DOES NOT hurt the Tire if max air pressure is run is my point, the ride will be different but if your not running a tire brand for the ride whats the difference?

Measure the depth and be done with it. I'll bet many, like mine, you cannot even measure the depth of the crack because it is on the surface of the tire only.

Cheers!

In the side wall of all steel radial commercial tires, there is only one ply. The tread area has 4-5 ply. If you read the sidewall labeling the "ply rating" is a throwback to the 50s. The actual number of plies will be listed on the sidewall.

Unlike trucks most coaches are loaded to the same weight, (within a few hundred pounds), whenever they are being driven...(I know mine is).
IMO tires run at the recommenced pressures, (per the manufactures inflation tables), will result in the best possible ride, handling and tread wear.
If you don't agree you are free to run your tires however you want to.

Typical, you avoided my question twice, few hundred pounds? 150 gallons of Diesel = 1350, 100 gallons of water, etc. if you ever roll out here in the Desert when it's hot, pull over and check your tire pressure....

What is your question?
I set my tire pressures to the recommended cold inflation pressures for the "loaded weight" of my coach... which only varies a few hundred pounds whenever and wherever I drive it.

Save your frustrations. Sometimes it's the quantity of posts......not quality.

I bought my class A last year with tires in the same condition. First thing I did when I got it home was buy new tires all the way around.
It's not cheap but my family's safety is priceless.

Please do everyone a favor and change the tire. The passengers and the people that are following you or passing you will appreciate it

Some of us have worn out many sets of tires, some have not.
When trucking I never really noticed a huge difference in ride when the truck was empty. Alot of the trucks I ran had spring suspension or rubber block suspension. May be my butt is paralyzed, but I call BS on weather you can feel a difference of 10 pounds of air in a tire when you are riding on air bags.
If you can then why do you need tire pressure monitors?
Before going onto trucking I spent several years in the tire industry as a repair tech. The golden rule of tires is under inflation builds heat and causes problems. That applies from a wheel barrow right up to a Large ore haul truck. Most motorhomes have a size of tire put on at the factory that will handle the weight when loaded. Tire manufacturers put a psi rating on the tire for a reason. The only tires I have ever had a problem with are ones that have lost air and ran low.
If some fell the need to run their tires at a lower pressure then feel free to do so. Its your dime.

We are missing the point. If the tires are inflated to the proposed psi per the manufacturer chart. Taken care of and kept out of uv light, they claim the tires are 10 year tires. So how after 3 or 6 years they are all cracking?

Yes definitely time to go tire shopping. Would even think of taking those tires on a trip. Sidewall blowouts on duels will sometimes take out both tires. Ekkkkk. Not a good thought.

It's always hard to judge from a smallish picture, but it looks like cosmetic weather checking to me. That is just a Michelin thing...my tires developed them in the first year, and I've put a ton of miles on them since then.

Tons of Michelin's are out there that look like that doing millions of miles a year. In my opinion, nothing to be concerned about.
