So, coming home from our recent boondocker, I decided to stop about 40 miles in to grab some food. My habit when I stop, is to walk around and look at, and feel, all my tires and hubs. I noticed that the RR trailer tire was significantly hotter than the other three. Made me stop and look at it more closely and I saw that the tread was rounded across the tire, instead of flat. So, tread's separating, but it's a "symmetric" failure, all around the tire. Rather than risk another nearly 100 miles, I changed the tire. DOT date of 2616 on all 5 tires, so > 5 years old. Now, my rig's placarded for D tires, which really are plenty of tire for a 10.5k GVW rig, given that an 8-ply D tire is 2540 lbs capacity, so over 10k lbs total. I'd probably hold my nose and buy Endurance (not a GY fan), but they don't make them in a D range in this size, at least that I can find. I did run a couple sets of the newer Carlisles on my old Komfort, but they were E rated. I liked them and had no issues with them. Almost always run at 70 psi instead of 80. Are there any decent D rated tires out there? Usual 225/75-R15 size. Should I just save some money and go with E rated Carlisles again, since I'd probably only run them at 65 or 70 psi? Should I bite the bullet and go to 16" wheels/tires? There are just so many more options with 16".

OMG...tires!!

Good to hear that report Lyle! I'm glad you noticed the issue before any damage. I know that Endurance do not come in that size. Another great option, from my personal experience is the Provider tire. It is the original new, design tire, been out the longest, proven, and comes in your size. They are speed rated 81 mph. Read about them at etrailer, or read reviews.

Go with the Carlisle HD tire and update to an E rated if available. They are doing well for many of us. You don't need to go to 16" tires IMO.

Huh?

2,540 x 4 = 10,160 lbs max tire capacity. I've got at about 1,500 on the pin, so 10,160 - 1,500 = 8,660 on the axles. 8,660 / 4 = 2,160 lbs on each tire...give or take. 2,540 / 2,160 = 1.18, or about 18% below the max load rating. Pretty good, if you ask me. If my pin load is more, then there's even less load on the tires.

Thanks, Jerry. I've seen Provider tires on a =lot= of trailers. Shoot, I think we have them on our 30' PJ gooseneck; G-rated, triple axle.

Later: Wow! Etrailer's =very= proud of those Providers. Higher than Endurance! :-)

Just talked to a sales guy at Discount Tire, and asked about "freshness" of the Carlisle HDs. He said that the =newest= tires they've seen lately are dated 2019 and =Discount= only has about 1200, total, in the U.S. Seems that Carlisle has discontinued the HD and is coming out with a new model...sometime. So, I my be buying Endurance, if I want to do some more camping this year. :-(

I plan on contacting Carlisle and seeing what they say. I'll update if/when I hear back from them.

Later: I just spoke with a =very= nice lady at Carlisle CS (>25 years working at Carlisle), and she informed me that the HD =is= still in production, but they are about 18,000 units behind in production of HD model tires, alone. So, I'll probably order some and hope I can get some fresh tires. Discount will let me refuse to take them if I feel they're too old.

She also informed me that Carlisle =will= cover damages if one of their tires blows out, or tosses its tread, so long as a road hazard is not involved. I had not ever heard this.

I agree, but I suggested read about. There are cheaper places to purchase that exact tire, even Walmart, at one time, not sure right now.

"Huh?"

Yes...LR E for the OP IMO. I don't want to be close on tire weight capacity. My TT can use Cs.....but I use Ds.
