Scott.. I read somewhere the Goodyear marathrons made an "improvement tire" awhile back and the tires have circle with a "S" in it on the side wall, right next the word "radial". I think this affect only the 15" tires. Just out of curiosity, do your tires have this "S" on them? ( my 2002 TT has the "S", good so far).

Maybe it's time we all invested in a tire pressure monitoring system for our RV's. The Goodyear Marathons enjoy a good reputation and I think they are good trailer tires. If it gets a hole and looses pressure I guess it does not really matter who makes it.

If your going to continue to use Marathons that would be a good idea. OR, upgrade a 16" LT tire/wheels. Searching around on Goodyear web on Marathon tires shows they are have a narrow tread with shallow tread depth and only 65 mph rated. The sidewalls are built to have a good ride. If you look at them the sidewalls are shaped like a basket ball which we learned a long time ago that with a narrow tread with the sides bulging out farther than the tires tread your very suspect to sidewall damage. Pulling cattle/emplement trailers on rocky roads/pastures will show up real quick how easily ST type tire are suspect to tread/sidewall damage. We use only 16" LT "E" rated tires on all our trailers and haven't had tire problems in years........JIM

A few things can cause a good tire to blow.
1- running the tire beyond the loaded rating. (OVERLOAD)
2- running the tires higher than the speed rating they are inteneded for. (Typically speeds over 60 or 65mph. )
3- running the tire on really hot days. (the hotter a tire gets the softer it becomes. Heat, speed, load, and road friction all work together to wear a tire out.
4- old and aged; a) high mileage b) sunbeaten c) winter frost/thaw seasons with load on the tires.
5- road hazards

We just got back from a long weekend on Sunday(11/13/2005) I had two Nankangs on the rear axle when I bought the trailer, two Marathons on the front axle, all ST225/75R15 LRD.
Trip before last, the first trip with the Pressure Pro/Doran Tire Pressure Monitor System. On the return leg the right rear (a Nankang)tire started losing pressure and the monitor sounded off loud and clear. By the time I was able to get to the sholder of I-64, the monitor showed 20 LBS remaining. I stood on the sholder (right rear) of the road and and watched the tire go flat. There was steel belt hanging out between two tread bars. Airstreams are not cheap to repair. The monitor paid for itself right then and there.
This past weekend (one Nankang on the left rear) I discovered a belt seperation (tread distorted and ugly) on the remaining Nankang. Changed it and drove home. Then I weighed each wheel with portable scales. The right rear was carring 1400 lbs and the left rear was carring 1200 lbs. In my personal opinion I learned two things, one that a tire monitor is worth the money; two, Nankangs are garbage.
This weekend, with the use of the two portable scales, I will endeavor to balance the weight between the two axles more evenly.
Anyone have any experience with the Cooper Custom Trailer Plus, a relitavely new tire?

The valve stem is still intact and in the rim so I think we will rule that out. I have weighed the trailer on a few different occasions and I am running about 5,500lbs on the trailer axles. The trailer GVWR is 7,500 and I have about 800lbs on the hitch. I think I can rule out running overloaded. My TV is a 3/4 Suburban and I use the EAZ Lift hitch without sway control. Seems to handle real nice.
I check the tire pressure at least monthly with a gauge; although not every trip.
One of the posts mentioned a max speed of 65mph which might be the problem. I like to pull between 65 and 70 most of the time. If 65mph is really a max speed rating for these tires then I have been running overspeed almost all the time. I'll want to look into that.
Prior to the blow out I did not notice any vibrations that might indicate a tire out of balance. It might have been and I just did not notice it.
I have "E" rated tires on the Suburban and they are great...did not really think about putting them on the trailer. Good idea.
I do intend to replace both tires on that side just to be safe...thank you.
Happy Trails...

haulin' cattle in a stock trailer can move big weight from one side to another especially a load of bulls or cows with calves. Enough that the trailer leans sometimes. I wouldn't worry over 200 lbs from side to side. Just pullin' in a strong side wind can make the down wind side tires/wheels/bearings run hot when on a long trip.....JIM

Road Trip,
A while back I phoned the customer service number at Cooper and ended up speaking with a tire engineer there. He was really positive about their Custom Trailer Plus and had nothing to say about their Custom Trailer tires. I'd give the Custom Trailer Plus a try if it came in my size. By the way, his strong recommendation for a 14" trailer tire was their commercial truck tire, the SRM II, which also would be a good 16" choice.

All men over age 50 should get an annual PSA blood test. Mine had a low reading, but the yearly jump was significant. The biopsy showed cancer just entering the aggressive stage. Dr. Hackenslash removed it.

In an earlier thread I described a huge "blister" that developed on the sidewall of one of my 3 yr. old Marathon TT tires. That happened the first part of Aug. Just got the adjusted bill on the replacement a couple of days ago. I was charged $67.97, the listed retail price being $106.25.
