Trailer Tires ????

Like what the heck. The sidewall is obviously larger then the sidewalls on the others. All 4 were from the same place installed at the same time. Y'all think maybe that I got a pair mis branded somehow and they are actually different tires?.................

I saw a photo of another person's matched tires; exactly the same issue. The outer belt(s) on the tire have failed and the rubber has expanded, same as a balloon getting larger. How many miles on these tires? I'd take them back to the selling dealership. If one has the problem, they all will, IMHO. Go with Sailuns, Goodyear, or Maxxis, in that order, if you can find a good fit.

Just installed Carlisle radial trailHD this week. 225/75/15E They have a speed rating or 81MPH. Hope they hold up well!!!

I'm thinking it's about to blow as well. It's not possible to find a tire to fit these rims not made in the C word. The one I picked up yesterday has the C word on it.

I might see if it will hold 100 psi if the wife aint looking.

The European option are not E rated.

RE no wheels.
How many bolts? What is Bolt Circle and what is the center bore minimum for trailer axles?

Better not to have to work on the traffic side in the event of more old tire trouble.

Yup Larger, round tire looks like possible defective. Get it replaced.

Be sure to capture the DOT serial and file a complaint with NHTSA.

ALSO how about posting the DOT serial so we can learn which factory made the tire.
It's easy to change the name on the tire sidewall by modifying the mold but maybe if we stopped blaming every tire company in a country and simply identified the suspect tire plant we might get an improvement.

my son in law purchased a 32 forest river trailer now two years ago...He has probably used it ( Florida only ) about 1000 miles over that period. Labor Day weekend we made a trip with them of 125 each way, most on the interstate...He had three blow outs during that period...and one on the way back...Also, had one flat tire last year...All the tires that blew were the tires that came with the trailer at purchase...Al blew across the thread, not the side walls....It is parked on a cement slab in the shade while not in use...Has anyone experienced similar incidents...btw...he always has checked his air pressure prior to using it...thanks

Sure! Just about everyone that hauls a trailer without knowing it's road weight and how it's balanced on the axles. Contributing factors are excessive speed and low tire inflation pressures. Another factor could be how level the trailer was parked while out of service and again tire inflation pressures in that state. Some people use their trailers as storage facilities while out of service with a complete disregard of tire overloading conditions.

Did he check the pressure regularly while it was parked? Tires have to be inflated all the time that they have a load on them, not just when rolling.

RE: Bad Tires???

If your SIL will just weigh the trailer as loaded to travel and compare against the tire capacity, perhaps he will get a clue why they blew. Mfgs are known to put the least capacity legal on a trailer/fiver that will pass regulations. I would guess he is close to capacity, and also a lesser quality chinese tire.
Solution is fitting a higher-capacity tire on the trailer.

1. What are his actual tire loads (each tire) as measured on truck scale?
2. What type, size & Load Range are the tires?
3. How old are the tires (DOT serial data?
4. Has he confirmed his pressure gauge is accurate (+/- 2 psi or better)?
5. Does he ever drive faster than 60 mph?
6. What is the lowest pressure he has ever measured?

& Has he made the basic effort to file a complaint with NHTSA for each failure?
