Popping (Exploding) Trailer Tires

I have popped at least 4 tires in the last 3 years. The last one was 2 hours ago in the middle of nowhere. That tire could not have been older than 3 years. When I mean popped these things don't just get a hole, they explode and disintegrate. Does anybody have any ideas? The boat is a 1995 200 VRS w a single axle factory trailer.

This trailer for sale is my exact trailer.

As usual, any help is appreciated.

What brand and model tire? Size? Are they ST-rated?

Agree...a lot of variables that can be attributed to failure.


OP...tell us more...please.

Tire Brand

The tire that just popped was a Power King ST205/75R14 Load Range C (1760lbs). The spec is ST 215/75R14 Load Rating C.

I replaced the popped tire w the exact same tire I have on the other side. I am now running 2 Greenball ST215/75R14 Load Range D (2200lbs).

I have been thinking that the problem was the trailer bounced around as we drove and that the fender well was hitting the side of the tire. I just had my 220 lb son jump up and down on the swim platform as I watched and the fender well does not really move that much in relation to the tire.

Could the problem be that I was running a 205 instead a 215? The tire wasn't wide enough? I don't know much about tires but that would seem unlikely.

Or was it that I was running 2 different width tires? That also would seem unlikely.

Thoughts?

Thx,
Kelly

Inflation Pressure

Probably 5lbs under full inflation and running 65 to 70 mph.

As someone with a heavier 200 VRS on a single axle trailer..
I haven’t found a reliably good tire. You need the highest load rating you can get - my boat is 2500 pounds dry, plus 1000 pounds for the trailer, plus any/all equipment in the boat; I use 4500 pounds as a WAG at the real world weight being carried by the tires when we’re going to Powell for a week.
I currently have Goodyear Marathons on the trailer; they’ve lasted three years so far with no issues. There were a few years where Marathons had a bad rep; but they seem to have gotten better recently.

Run them at the max pressure on the sidewall - 80 PSI on mine. This reduces the heat buildup in the tires.

Check your trailer axle to make sure it’s still straight. It’s possible that it’s been bent; if so, the tires will get abused badly which can lead to failure. Perhaps pull into a trailer repair shop and have them take a look.

Check your brakes. If they’re dragging (or you drive on long downhills which will have the same effect), the rims can get hot enough to cause a tire bead failure.

Good luck

^^^THIS^^^

What pressure were you running? A lot of people mistakingly air their trailer tires like they would their car.... say +/-35psi... which is usually way too low for a trailer. I can't say that's your issue, but it's definitely worth consideration if you weren't running the previous tires at the max cold sidewall rating.

Bummer. Ive had blowouts and they suck!

Gotta be way too much heat but I can only guess why

You put gear in the boat when you haul it, is the gas tank full? Id run it as light as possible.

Do you have trailer braking? Might wanna try locking out those brakes. If they are slowing your whole rig down that would do it.

Could be bearings, might wanna jack up the trailer and check that the wheels spin freely/easily.

Might wanna buy one of the cheap harbor freight infrared temp guns. Tow it 20 miles and then use the temp gun to investigate where this heat is coming from?

Good luck! Interested to hear what the problem/solution ends up being.

Might have a partial answer. I was running one 205 and one 215. The 205 is the one that popped. The tire guy said that the actual height of the tire is dependent on the width as well as the height rating (hope I got that right). He said since the 215 was actually slightly taller it puts stress on the sidewall of the 205 resulting in the blow out. If that is true, it would explain why the tire apparently disintegrated.
