Michelin Tires - Agillis 225-75-R16

[RF_Burns]

I clicked on your link and checked them out. One thing that stood out in the specs was 90PSI required for max load (2680lbs). That's 10psi higher
than other 16" load range E tires. I wonder if the ride would be more harsh?

I went from Michelin LTX to Toyo Open Country because at the time I couldn't get the LTX ASAP. I found them quieter and less harsh ride. They are 7
years old and I'll likely do them again.

Hi Bruce
Yes the ride would be harsher at the higher tire pressure but there would never be a reason to put that much pressure into the tire.
That is really just an indication that it is a stronger tire. Your motorhome would rarely be loaded more than 12,000 pounds or 2000 pounds per tire. So 60 to 65 psi per tire would be more than enough. You should never load a tire up to its maximum pressure. Check the specifications of your tire and determine the pressure for the load you expect to actually encounter. It will likely be less than 65 psi. That will give you a softer ride than a tire which has a maximum load of 65 psi.

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.

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.

Hi Emery,
You are correct that I would never need to run them at full pressure. But I was thinking why would this tire need 90Psi while most others need only
80Psi at the same max load capacity for the same size tire. Would this mean I'd need to run near 10 PSI higher to carry the same load than what I am
running now?

I run 65 front and 60 rear on my Toyo's.. I was just pondering if that would be true and how that would affect ride. I guess I should have checked to
see if there was a tire pressure chart for that model.

[adolph santorine]

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…..

Rich, Michelin does Not own Cooper. You are probably thinking of Goodrich which they now do own. Cooper is a USA company.

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.

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.
