A couple of years ago my SIL had a tire go on his toy hauler before he realised
it,the rim was destroyed.He notified the mfgr of the rim and was told they would need to make a new one to match what he had.When they found out what he was using the rim on,they refused to OK the use of that rim on his trailer.It ended up with the trailer dealer eating the cost for 5 new rims and tires.
The trailer manufactures are always looking for a way to save a dime.In this case it sure seems to me that the dealer/manufacturer owes the OP a new set of wheels at the least.

understand, but in my view there is not enough headroom on most trailers...
This forum is filled with blowout stories.. take away the ones caused by under inflation, poor care,, excessive speed etc... and I still bet a fair amount would be eliminated by one step up in tired rating...
my TT might well be within the weight boundaries of four D-rated tires, but don't personally think they were appropriate. Should have been E-rated from the factory...

An over-rated china junk tire is still junk. These blowouts are caused by poor quality and defects, not borderline weight ratings. If you truly want to rest a little easier, just go to a properly rated quality USA tire.

Actualy my tires and wheels are plenty rated for my rig. My rims are 15x7 and rated for 2800 lbs each and my tires max at 2873 lbs at 65 lbs max pressure but the rim is stamped 60 psi. It don't say that its the max but I bet it is? My camper weights 7502 with 2240 cargo capacity so my tires and rims cover this weight.

I discovered that the rims on my new camper are only rated to 60psi but the tire pressure decal applied by Coachman states tire pressure to be 65psi. Don't the rim max trump the tire rating? Like I can't run 80 psi in the tires if the rim only rates to 60psi.
If my GVWR sticker said 65 psi minimum and the wheels said 60 psi maximum I would be back to the dealer for a warranty adjustment.

Much worse! The rim then becomes square making for a rough ride.
Actually I have talked to long term tire men locally and they just laugh about rim pressure concerns +/- 25 PSI. I know I have a 12" China rim ($12) that is aired to 90 PSI because of a sticker on the rim that said air to max PSI stamped on side of trailer tire. It is a 2,000 pound axle and has not been over loaded.

Since THEY recommend the tire pressure and didn't provide you with wheels that can handle that pressure they OWE you the correct wheels for your trailer.
Good luck / Skip
In fact, this would be subject to recall.

A tire that fits on a 15" rim that has a load rating of 2873 pounds at 65 psi? What tire is this? There are a whole bunch of people with ST225/75R15 load range D tires that will be interested in upgrading to what you have. This tire sounds more like a load range E tire.

Slow failure will be a tire/wheel assembly that is a leaker and proper inflation can not be maintained. On a sudden failure the wheel comes apart.
Steel wheels usually have cracked welds in the rim contour.
Aluminum wheels usually fracture.
