Unless you have a 23 with 14in original equipment wheels. Then you have to replace the 14s with 15in wheels before you can install that sweet tire. Note this tire is a XL P tire, which is an extra load passenger car tire. It gets derated by 10% when used for trailer service. But since the 23 gross weight is around 1500#s per tire, there is no problem with a capacity of 1967#s per tire.

Travel safe. Pat

Actually I think a C load rating is 50 psi. A D is 65 psi.

The new Michelin Defender tire 235/75R15 has a higher load rating than the current Defender, so even after the derating of 10% it will de a better fit for all 23 & 25 ft Airstreams. It hits the market this month & that's why I'm holding off buying the Maxxis ST tire, just can't decide!

I just upgraded to the 16" wheels and Michelin tires and besides the reasons already mentioned I'm looking foreword to the increased ground clearance. I've drug the rear skids once and that wasn't a good feeling.

\MY Michelins are rated for 2100+ lbs. each, for a 30 Flying cloud that grosses at 8800 lbs. leaving me short about 400 lb.s at gross.
Means that I cannot load the FC to max, although I seldom do anyway.

Remember, all of the trailer weight does not sit on your trailer tires.

Great point.
So in Mel's case a trailer with GVW of 8,800 lbs., less tongue weight (carried by TV) of, say, 1,000 lbs -- so his tires must carry 7,800 lbs -- a 600 lb. safety margin.

No need to change wheels because overall diameter is just .1" larger than the 15" Marathons. Also a few hundred pounds of Xtra weight carrying does not hurt.
Except that, in order to gain any benefit from the additional capacity of load range E tires, you will have to run them at the higher inflation rate of 85 lbs. Run them at 60-65 lbs, and you will only have the weight capacity of a D rated tire. The minimal suspension travel that Airstream trailers have requires that the tires absorb impacts to protect the trailer. Running E rated tires at 85 Lbs will not provide the cushioning needed by your relatively light trailer.

There are so many threads about this stuff... I'm still scratching my head, though. I don't understand why everyone wants to max out their tire inflations.

I have a 28' 2013 International, which is dual axle, with the stock Goodyear ST225/75R15s. I had my trailer weighed at a truck stop when we were loaded up on a 6-month trip. It came in just under 7,000 lbs.

If you divide 7000/4, you come up with each tire being loaded with 1750lbs. If you look at Goodyear's inflation guide for those tires, it recommends 35lbs of pressure for 1760lbs of weight, cold—even thought the tire can take 65lbs of pressure, for a max rating of 2540lbs. Airstream says the trailer's loaded weight is 7500lbs. Divide that by 4, and you get 1875, which would be 40lbs cold. So, I should be running between 35 and 40 lbs cold, if I want to error on the cautious side. Why are people jacking them up to 65lbs?

Is there something I'm missing?

Good questions, and I am curious to find out. Here is a link to the information you referenced.

Don't forget that the weight on the tires is NOT evenly distributed. I'm using a 15% variation until I find better data.

Also, don't forget to provide a margin of unused capacity - commonly called "Reserve Capacity". I use 15% there as well!

Ok, I can understand the minimal suspension impact why the 60-65Lbs instead of the 85 Lbs. In our case since we do not travel with any liquids in any tanks & put most if not all of our travel needs in our tow vehicle which is a Nissan 3500 HD cargo van I am not concerned with the xtra weight. I just want to get away from the Goodyear brand hoping the added 2 ply will give a little added protection from a blowout & still stay with a tire designated for travel trailer use. I am also thinking since the added weight we would add to the dry(empty) trailer weight will not exceed a few hundred pounds maybe its better to go with a Michelin 15" that just meets the load capacity in which we travel with ...... any thoughts ???

We installed the 15" Michelin LTX (P) 235/75R15 XL tires on the stock wheels of the 2013 25FB with no problems. Going from 14" tires and wheels to the same 15" tires on the 23D required new 15" SenDel T03-56545T wheels as well with the five hole pattern for the 10" brake drums.

Going to the 16" tires and wheels on our 2014 Classic required new wheels as well and we acquired the same tires and wheels Airstream is now installing on 2015 and later Classics and the Eddie Bauer models.
