Did you use an inflation chart to set the pressure in the tires or just the max as stated on the tires.

I have spent the last 2 weeks looking for a set of tires for my trailer . I have been using Tow Masters but they are now made in China. I have seen the Goodyear Marithons do the tread seperation thing, on a friends trailer, and have great reservations about them. The Cooper Customes, that I had considered, are on a 3 week back order which leads me to think they are still on the boat

I had hoped to leave next week for Newfoundland but not sure if I will have tires by then.

HowieE,

Since the trailer weighs in at 8400# fully loaded, I felt it was always best to keep the pressure up at 65 psi on all four tires to avoid overheating/separation issues. Maybe I was wrong? I always check tire pressure the day before leaving on trips, and have never experienced a significant loss (i.e., more than 2 psi) on multiweek expeditions. The ballooned tire currently shows 65 psi, so tread separation has not yet compromised the ability of the tire to hold air. The roadside rear tire, which exhibits less ballooning, still shows 65 psi. I hope this contributes to the discussion.

Michelin has an RV information packet they send out on request. Email them and ask for it.
My opinion was that the problem was the rubber compounds used in the ST class tire would not stand the heat, so along with Bob Thomson I went with the Commercial T/A.
I am in agreement with Andy of Inland RV in that high pressure tires will damage/beat up the trailers, that was another reason I went with the Load Range D tire. May I recommend that you decrease the pressure in the XCA Rib LRE to reflect the load on it as shown in the charts from Michelin. After all the speed rating of the Michelin is indicitive of rubber compounds that will maintain their integrity at higher temperatures.
The actual axle loading can readily be obtained from a CAT scale.
I'm carrying 3200 lbs per axle as per the CAT scale measurement.
I reduced cold pressure to 60 LBS from 65 LBS and there was a noticable difference inside the trailer upon arrival at our last outing.
Just my 2 cents worth.

Hi Beginner,

We plan to mount Michelin XPS Rib tires on our trailer, size LT225/75R16 LRE

What follows is the inflation pressure table for this tire and can be found at Michelin North America RV Load & Inflation Tables

PSI
40 45 50 55 60 65 70 75 80

LBS
1650 1790 1940 2060 2190 2335 2440 2560 2680

I plan to run the tires at 65 psi. This amount of pressure should be adequate given the weight of our fully loaded trailer. Not to much, not to little, and hopefully just right?

Paul

Heard of a lot of tire failures and blow outs during recent trips this season. Maybe a monitoring system would be a good addition.
Hi peegreen,

We lost two tires on the NEU Caravan (first blow out damaged the second tire, it blew within 60 miles of travel after we replaced the first one). But they were 6 years old and had spent much time in hot, dry, AZ so we figure we really should have replaced them before we started on the trip. We have replaced all the old tires now, with Marathon tires. We *will* be purchasing a tire monitoring system that monitors both inflation and heat. We don't want to risk any damage to us or our Airstream in the future due to tire problems.

Nice pic. RICKO provided me with ALL the details.

Yes, those are his little legs (and my sister's) reflecting in the shine of "The Tube's" side in the photo.

I replaced my OEM Marathons before I started my cross-country trip in June with new 16" rims and Commercial T/A LT 225/75-16 LRE tires......same size and spec that I have on my Sprinter (although they are Michelins.). Ran 3700 miles from FL to OR at 65PSI with Pressure Pro tire monitors AND Ride-ON tire sealant, and never lost an ounce of pressure. Running temps were exactly in line with the 4 tires on the van, and I have much more confidence in the T/A's than the Marathons!

Well I broke down and bought new 16 in wheels and Michelin LT XPS 225 75 R 16 tires. In my investigation I got good help from Michelin and great help from Scott at Sparks of Imagination on the selection of a good trailer wheel.
16" ALUMINUM TRAILER WHEELS FOR FIFTH WHEEL TRAVEL TRAILERS, TOWABLE RV'S, CARGO TRAILERS, HORSE TRAILERS, LIVESTOCK TRAILERS AND MORE

Now if UPS does there thing I will be off next Saturday.

#2 because it has a 5mm + offset that will move the tires 5mm towards the frame of the trailer and give that much more clearence to the fender. That was the recomendation.

HowieE,

I was worried that 16X7 wheels capable of 80 psi and 3200 lbs. were being discontinued throughout the industry. The eagle alloy rims (series 055) we purchased are hard to find, and I think discontinued by the manufacturer. I was worried about what we would do if in the future we need to replace a wheel for some reason and were unable to find one for sale. But then you come through with 4 stylish choices. Good hunting!!

Are you doing anything with the spare?

Of the 5 total Goodyear Marathon tires that came with the Airstream, 3 have failed within the past year. When the first one failed, we replaced it with the spare. Now that one has failed (with less than 2500 miles on it), as well as another one. All of the failures have been in the rear tire position on either side of the trailer. All of the failures have been due to separation of the tire tread from the underlying beltsPaul and Miriam
Wow, this is sobering since I'm pulling at least that much weight and sometimes more on my Classic. Since everything has failed the same way, and you have such an excellent example that yet had not blown out, is there any way that Goodyear can get to that tire and give you a report as to what is going on?

We've beat this Marathon thing to death in different threads and in most cases the standard line from most tire manufacturers is that you overloaded the tire or it was under inflated. Unfortunately by the time the manufacturer sees the tire it's in shreds and I question how they can make those assessments. Especially in situations where the owner did their due diligance before they pulled out that day. And I'm not just picking on Goodyear because I've talked to folks using other tires, even the Michelin brand.

I, like you watch tire pressures carefully, I don't exceed 65 mph, and certainly don't overload. I hope you can follow up on this since I certainly would love additional input to help guide me as to the brand I replace with next year.

I've had Marathon's now on three trailers all of which have been good experiences. We've championed these tires since as I've noted before, there are more Marathon's on new travel trailers than any other single make of tire. With that in mind it's not unusual to expect that the universe of reported failures would be higher. The key to this is when you hear of folks who take care of their tires, keeping inflation correct, not overloading or traveling at excess speeds, not keeping a tire beyond it's normal life, you just get that uneasy feeling in the pit of your stomach as to whether there is a quality problem.
