I had the 250 DA, ran the max cold press. for those tires i had, 50 PSI, and no problems. My 280 DA however has 65 max cold PSI, and i run them there w/no problems.

Another vote for max cold inflation listed on the tire. Since you have blown 2 tires there is a possibility the tires that remained were overloaded during the blowouts. I have seen the remaining tires last a very short time after the initial blowout on that side of a trailer. You definitely want to carry spares and be prepared.
I found it interesting reading several comments about putting "E" rated truck tires on the trailers. I tried to do that in WA and nobody would do it. I checked with several different tire stores and they all said the same thing. Apparently there is a difference in the tire bead between trailer tires and truck tires and they all refused to mount truck tires on the trailer rims.
Do yourself a favor and do a lot of reading on the Marathons vs Maxxis E rated. My rims said on the inside 80psi max so I changed the stems to metal and run 80psi. Made my trip two weeks ago to Miami with no problems for the first time:smt038 The Maxxis are just a little more but well worth it! I scaled my set up (weight slip posted here somewhere) only to find out that my boat and trailer fully loaded is 14 and change:wow: The Maxxis tires are rated for 2830# each! I'm a believer in using tires well above what is required to keep the heat in check. I towed over 600miles all together with no issues! My outside temps were 96-98 and I towed 65-70mph. That wouldn't happen with the Marathons or Carlisles.How timely. Last night I blew my first tire on a trailer in 15 years of towing – good thing it was still light out as I watched the “rubber fly” otherwise I probably would have destroyed the wheel/rim and had “sparks flying”. I am running the Goodyear Marathon ST225/75R15 (D) on a dual axle Heritage trailer (tows the 290 Sundeck at approx 10K lbs. for boat/trailer/gear). These tires have about 3.5 seasons on them with >16K miles on them. I always keep at full pressure per the tire specs – 65 lbs. when cold. I had just checked them at a gas stop and 15 minutes later it blew. This heat is brutal on tires!! – no matter the manufacturer. Looking at the tire, the roadside service team agreed that blow out was most likely heat related after checking brakes and other tires. I plan on replacing the other 3 now and getting back to 4 fresh tires – planned to go with the Marathon’s again as all of the manufacturers seem to have positive/negative reviews.
What load range tires do you have? I run load range E at the max cold PSI and never have a problem.

My local tire owner told me at 5 yrs. (from date of manufacture) your riding on borrowed time for a blow out. I too have used goodyear marathons w/o a problem. Alot of tires are already a yr. or two old before they are even mounted.I inherited a mismatched set of LT tires on my trailer and was going to replace them, then my trailer guy suggested letting nature run it's course and be prepared for the failure. Just ran 3 hours between 60-80 mph in 90 degree heat with no heat up, while having two brand new tires as spares. Checked tires and hubs twice in route by IR.
I have used Marathons for years on multiple trailers with nary an issue. I think some failures are the tires and some external factors not easily pinpointed. The variables are considerable. I do know that tires often fail when you are least prepared for it, kind of a "karma" thing. Did I just say that? Ooops! MM
MM, where did you find 90 degree heat this time of year?
