Spare tire blew up! By itself!

Ccmano · 10-21-2020, 02:51 PM

Can't say I've ever seen this before. Went to winterize my 2020 Cougar 24SABWE and walked to the back where the spare sits. At first I thought an animal had chewed up the cover. Then noticed tire cords sticking out! Removed the cover and saw the tire (it's brand new, never been on the ground) ruptured from the inside out with tire cords sticking out. My guess is the cord structure was defective and direct sun on the tire with 80psi (cold) in it caused the pressure to build and rupture. Still it shouldn't happen! Glad I didn't have to actually use the spare! So off to the dealer to see what they will do....

should be interesting. ��
Has anyone seen this before?

Interesting, but even more so if the tire brand, manufacturer, date of birth...(build date) were known. Odds are your dealer will tell you to 'sit on it and spin.' Try the tire dealer if you get no help. By the way, your tires build date is usually on the back side, a four digit number, i.e. 2618. This would mean the 26th week of 2018.

a good reminder to get those junk tires that came with your trailer off immediately, get some carlisles, and put the old trailer king junk(assume) on craigslist.

Good point, I'll check the tire make and build date and post them. It is a Trailer King I believe. My guess is the dealer will be of little help, but who knows.

Not sure what caused it but my brother had one do the same thing under his Toyota pickup. It was less than a year old. I would love to know the cause. My 99 Chevy still has the factory spare under it and never had a problem.

You might refer this "incident" to TBC Corp. for their resolution/guidance.

So now they're "China Time Bombs" too.

Sarge2 · 10-21-2020, 04:12 PM

I'd be curious to know how much pressure it would take to do that? How warm in your area was it getting? At 80psi the pressure would have to rise substantially in that tire to cause that... unless of course the tire was defective in the first place..
After I bought mine I took tire off the mount and inspected it to make sure it didn't seem to have any bulges or waves in the sidewall or splits in the tread areas... Mine has Trailer Kings on it... wish they were 15" but they are 205 75R 14's.... Hate to think about changing wheels but I'm not convinced that 14" tires belong on this trailer...and there isn't much of a selection of tires for 14" the 14" wheels are sharp looking but safety comes first...

LOL!

Since I last parked the trailer temps have not been over 90' degrees. Mostly low to mid 80's and now 70's. Even if the ambient temp had been in the 100's with direct sunlight on the tire this should not happen. There wasn't even any load on it.

I can't imagine that the working temperature on a spare can be worse than the working temperature on a rolling tire in the same vicinity on the same day; and even though you weren't rolling yours, other people were.

Gegrad · 10-21-2020, 05:38 PM

Wow! Can't say I have ever seen that.

**flybouy** · 10-21-2020, 06:17 PM

Looks like they forgot to put the pin back in the handle on that grenade.

**sourdough** · 10-21-2020, 07:03 PM

OK, after looking at that pic of the spare all evening, and it being so "odd"...are we sure that the black cover isn't showing the long hair of an "older one" whose head just exploded over ??? and their hair is sticking out

Don't think I'd use that 21 year old spare under that Chevy.

What are the chances that happened right on top? This looks too strange to me. Yeah it’s a Tire King, but still. Are you sure someone didn’t come by with a buck knife in hand, stab straight down, and slice and tug on it to destroy it? When you said you “went to winterize” I took that as the trailer is in storage?

**flybouy** · 10-22-2020, 05:58 AM

One question that I guess the answer to. Have you ever checked the air pressure in that spare? Anything is possible including someone at the dealer pumping that tire up to 100+ psi thinking they are doing you a favor in case it "leaks down". Seems to me that if there was enough pressure for whatever reason that the valve stem would have failed before the tire but like I said, I guess anything is possible.

Bill, your buck knife theory... have you ever tried to slice a tire tread? The sidewall maybe but if someone did a "Rambo" on that tire I wouldn't want to mess with him!

Back in 1978 bought a new Ford Granada. Lived in Junction city Kansas at the time. Summertime and one morning noticed my trunk on the car was sprung. Tire blew up just like yours and destroyed the trunk deck. This was way before china bombs so it does indeed happen. Also seen a few when working road construction on heavy equipment.
