I perhaps need to clarify a bit;  I entirely agree with Ed here, Dean, though all we can offer is opinion based on photos and not personal inspection.  Whatever the cause, if the apparent sidewall damage is as severe as it appears in your pix, I certainly would be replacing the tire right away, and probably both front tires to preserve a wear and age balance up front.  At 5 years though, that is your call to replace both or not.  I sure wouldn't be using a freeway to get to a dealer - maybe even see if he can come to you.

Regardless, a Goodrich rep. should be consulted in case the nature of things provides any warranty benefit in the process.  And take advantage of the opportunity to have the other tires inspected, if not strictly for the advisable timeline noted in the links from my previous post, but also in case the damage is from a road hazard that impacted the rears in a hidden manner.

@Joel: did you get your air leak resolved, either at Henderson's or BCS? Our red tank is also emptying much faster than it should. Had it into Bend RV repair and he found a few leaks, but not the major culprit. Thinking about taking it into BCS, and wondering how many hours it took them to find your problem. At their labor rate, I know it's going to cost me a few $$ to track down and repair the leak.

Bill-
Henderson's found a cracked fitting, but fixing that didn't do the trick.  BCS found a bad air horn connection, but the red needle still tanks overnight.  Don't know where this leak is, but it's not making itself obvious and is costing some in the labor dept. 

I have noticed that the back of the coach doesn't seem to go down when air leveling, or when I dump air;  hard to ascertain as I can't hold the dump button and watch the back end, and potential helpers so far are always busy.  On leveling, the front is inevitably low on sites I've been to so far, and it airs up in lieu of the back dumping.  When I deliberately (manually as opposed to auto-level) try dumping the rear, I get a repeated psst, psst, psst, psst rather than the usual steady air release.  No one that's heard it so far has explained it, which is a bit discouraging since the sound I'd expect to be revealing to someone in the know.  Hate to think I have to travel back to HWH to resolve it.  At least it levels and seems to stay there for awhile.

Whether this has anything to do with the air loss from the secondary tank, I have no clue.

Soooooo... here's the deal.

I have access to new Goodyear 505D Fuel Max tires.  They are 295/75R22.5 and they are a really good price.  They are a long haul commercial truck tire.

Here are the specifications as best I can determine:
     Load Range G  -  I think that means 14 ply
     110 psi max cold
     Rim 8.25 inch
     Max speed - 75 mph
     Single max load  -  6,175 lbs at 110 psi
     Duel max load  -  5,675 lbs at 110 psi

I have 315/80R22.5 Dunlops on the front.  If I bought these Goodyear tires, then I would need six.  I have 295/80R22.5 Michelins on the duels and tags, and one of them was replaced two years ago.  I had been thinking I would get five new Michelins or Toyos or whatever - all 295/80R22.5.  I could not run five Goodyear 295/75R22.5 tires with one Michelin 295/80R22.5 on one of the tags?  I am thinking not!

The difference in price between getting five Michelin Advantage (FMCA) and six of these Goodyears is about $1,500.  But I am afraid the Load Range G / 14 ply rated Goodyears are not heavy enough, meaning weight bearing capacity, for my coach.

What y'all think?

David,
If the weights of your coach are similar to the 00 Marquis we had, it is too heavy for the Goodyears. My front corner weights were ~6200 and ~6400 lbs on that coach.

I thought my post was clear in that I have 315/80R22.5 Dunlops on the steering axle.  What I need to replace is five of the six tires on the duel and tag axles.

Sorry about that. In any case, unless you post the weights on the corners of your coach, we're all guessing.

I just replaced my Toyo tires with Double Coin tires. I had never heard of them but truckers use them and they have a very good reputation among truckers.  Another very tire is Hankook tires.
