I thought about the knife theory as well. But as has been stated if you've ever tried that you'd see its near impossible to cut through the tread belts of a tire like that. It certainly wouldn't cause the belts to come out as seen here. As for checking the pressure in the spare, yes checked to 80psi before a recent 1000mi round trip. The trailer is in storage but it's a private facility with only 6 other units. Ultimately, we may never know, but to me that's a rupture of a defective tire.

Nope! Never needed to or felt the urge to slice a tire. I do know that once a puncture starts it can rip itself open more and usually violently due to pressure. So there’s my theory - Rambo or not - its only a theory. But I now see another post about this happening in the trunk of a car. Glad I sold those 1 year old Trailer Kings (that I see I called Tire King... oops! ) recently.

Just another "wild theory":

I've got a Craftsman digital air pressure gauge that has a tiny button to switch between PSI, BAR and kpa. It's easy to accidentally change the setting while holding the gauge on a valve stem.... 80 PSI is 5.5 BAR... If a "multiple scale gauge" had been used AND the scale accidentally changed from PSI to BAR, and the tire inflated to 80 BAR, it would have had around 1100 PSI in it...

It would be "very frightening" to have that happen, and the tire might well have exploded with someone standing in front of it, but.... "is it a possibility" ?????

I honestly can't see a tire shop with a compressor capable of 1100 psi..

No. Not possible.

Think about it; all those staples blown thru the wall, every screw you can find stripped, the self tapping screws all under your trailer stripped....that has to be it.

Just got my trailer back a couple of days ago and finally had an opportunity to "crawl under it" and pay attention. Underside, J wrap, supports and other paraphernalia SO much better and stronger than my Cougar. Feeling impressed but started to just "look around" under there. Hmmm, HOW do you screw those 1/4" retaining screws in so tight that they actually shred the aluminum wrap? Can the Amish not see, hear or pay attention? It was truly unbelievable. Spent an hour going to the hardware store to get more self tapping screws and fender washers to repair the "flopping" J wrap and other loose pieces. Yep, can't think of anything else other than that 2000psi compressor letting those "craftsmen" inadvertently run a screw, at 2000psi, right thru a piece of aluminum. Once we understand that, we can easily see how they would put 1100psi into an 80psi tire....they just got lucky before they sent it out. Now we know the rest of the story....

Before joining this forum in 2012, on the Artic Fox web site before that people posted lots of spares blow up with cover on. Poster said it was a new tire, well really it was what ever date is posted on the sidewall. If used or not they still rot.
I have checked the siding of my trailer here sitting in the sun. The air temps could be close to 100 and the TT siding was 130- 140 f. Could that be enough temps transferred to the spare sitting inches from the trailer side. I do not keep the spare mounted on the trailer. And I agree spares with covers on them should not blow up, but it has and does.
Common theme heard before was all or most blew up while in the summer and in the south/southwest. Back than the China Bombs on those TTs where named Trail America as I recall.
Unless I missed it we still do not know the age of that tire.

Just as a follow up for those wondering. The tire is a Trailer King, produced in the 43rd week of 2019 as evidenced by the attached photo. There is no circumstance under which I would consider this situation acceptable. I have an appointment with the dealer Friday. I am posting a claim with the tire distributor tomorrow. More to follow...

Good luck and keep us posted. Wishing you well but I'm always amazed at the excuses some of these outfits come up with.....

That's the right thing to do, many just move on and the dealer, tire company and government never hear about a problem with a tire.

They need lots of pressure so that all those pantry shelves that they staple underneath the end rests instead of on top of them will stay fastened.

Very interesting. Look where that tire was built.

B4 = TAURUS HUNGARIAN RUBBER WORKS - BUDAPEST - HUNGARY

I wonder what percentage of recycled carbon black is allowed to be used in the production of new tires in Hungary?

China about 20%. To be fair, Bridgestone uses 20%.

I'd be interested in knowing the temp difference under a "dark-colored" or "black" spare tire cover versus a "light-colored" or "white" spare tire cover.



Is it possible the black spare tire cover sitting in the sun every day would cause high enough temperatures to wear out the tire any faster than a white spare tire cover?

LOL - my Harbor Freight hotdog barely gets to 100

Good info. I will at least be monitoring my "China Time Bombs" and checking the dates.

Dealer should be cooperative and reach out to Trailer King. My buddy got all 4 of his replaced when 2 showed signs of tread separation (Castle Rocks).

John,
This makes me think about the other four tires... you know the ones kept covered with black vinyl slip covers when at home. Black because they look good and hide the dirt. Hmmm.... guess I’ll be considering white covers for the new Carlisles.

The tire covers I purchased are silver as I considered that last year my TT sat in front of my pole barn all winter... the left side faced south, nearly in full sun all day (when sun was out)... figured silver would reflect some of the heat...took spare off completely and put in the barn.

Tire DOT Code

Look at the DOT Date code on the Tire.. If the tire has Never been used but is 5 Yrs old It is still Expired they rot from the inside out. When you replace it look at the Date on the New Tire. Sometimes they go on Sale and then you find the date and see that you did not get a deal.

My 2014 Cougar 28RLS came with trailer kings & were replaced in 2020 due to age not wear . Spare had never been put on the ground.
