This spare trailer tire got ripped to shreds, but why?

Folks, we don’t know the story about this spare trailer tire ripped to shreds, and neither does reader Dana Eulert, who sent this to us. But the moral of the story? Don’t do this at home… or something like that?

Dana emailed us and wrote, “Saw this at a Nebraska gas station while traveling cross-country. I don’t know the story behind it (the driver wasn’t present). I’m thinking that they didn’t have a TPMS? Maybe they’ll purchase one now.” Um, yeah, we sure hope so…

Our tire expert, Roger Marble, says, “That’s what happens when you drive a few miles on a flat tire. Obviously, that person did not have a functioning TPMS.”

And the real question here: Why is that still on the back of their trailer? You’d think removing it would be a top priority… (Or maybe they just like the attention it’s getting?)

What else would you do with your flat tire after you put your spare on???

I have not installed my TPMS yet. Metal stems, you say. Why is the tire outside, probably it stinks, and the owner doesn’t want it inside.

I have TPMS! I had 4 brand new tires & was traveling along, TPMS notified me I had 0 pressure right rear tire. I stopped & tire was flat. It blew out entire valve stem & TPMS sensor. Got it fixed, tow guy said it was due to rubber valve stems that were put on with new tires. I was back on the road & a car honked & said I had a flat tire. I stopped & a different blew, entire valve stem & TPMS sensor was gone. NO WARNING this time. The tire shredded & I was 5 miles from campground. Unbeknownst to me, it cracked leaf spring & tore underneath wheel well. I had all 4 tires replaced & METAL valve stems put on. At end of our trip, leaf spring broke & 2 2 new tires were destroyed! That is another story.

But reason for this is not all TPMS sensor warns you if they blow off with copper insert in stem.

When a rubber stem blows out of the wheel all the air will be gone in seconds. If you were driving when the stem left the wheel that means that the TPM sensor was out of range in seconds so while it may have been sending a warning signal I doubt that it had the range (1/4 mile or more) to alert the monitor. Your experience is a perfect example of why I strongly advise that metal bolt-in stems should be used in RV applications. I also suggest you review my blog post on Testing TPMS so you know your system is working as you expect.

I have had this happen. The tire blew and I put the spare on (although my actual rims do not fit on the spare tire holder). I drove to the next available town and replaced the tire. I do have a TPMS. TPMS only works if there is a slow leak, not a blow out. I have had 2 leaks the TPMS caught. I have had 2 blow outs (the tread seperated and then the inner tube blew), TPMS did not catch these. I heard the blow outs and pulled over quickly.

TPMS is designed to “Monitor” the tire pressure. I know of no commercially available system that will warn of a belt separation. That is why I advise a close inspection at least once a year or each 2,000 miles.

I’m surprised the aluminum wheel wasn’t damaged.

The only TPMS (popular brand that I can’t remember now) had me at the side of the road with a flat tire. The tire guy later told me the caps were too heavy for the stem and caused leakage. I bought another brand (this was 12 years ago). Same thing happened even after I had new stems put in. The reliable solution? My Class C doesn’t move without me manually taking the pressure of all six tires with a reliable reader. No exceptions. Never have had a problem since — and I would never buy another TPMS.

you need metal valve stems for TPMS and you will not have that problem

Not all rims work with metal stems. My local tire shop tried to install metal stems and they didn’t work with the rims. That was 5 years ago so I’m not sure of the cause but it seems like the aluminum rims were too thick for the stems to seat.

unless your aluminum rims are 5 – 6″ thick at the valve hole the problem is that your tire store doesn’t know a lot about bolt in stems. My reference book on stems shows dozens of options you can email me if you want help tireman9

I had a tire blow just like that one. All that was left was the bead and shreds. The tire absolutely exploded.

It probably a sidewall run low flex failure THIS blog post has many pictures of sidewall failures due to run low. When a tire sidewall lets go it does make a loud sound even if only 10 psi is left in it.

I also thought this rim seemed to nice for a RV. If this was on a RV and it blew, it would sound like a bomb going off. I’m sure they would have known it. I heard one blow as it was in the passing lane in front of me. Not everyone has the money to afford a TPMS system for their RV. If people think it’s to dangerous not to have one. Than they need to pester Dept of Transportation to force RV manufactures to install them at the factory.

A rim like that isn’t very expensive.

4 tire TPMS can be had for about $300. Other than the $2 batteries, they do not wear out so can give you improved safety for many years. Some advance warning could even save a tire not to mention $thousands of damage. What makes you think that the RV company would not include the price of a system in the price of your next RV if DOT required that feature.

Forget TPMS. Before TPMS systems drivers with trailers could feel, hear, see or in some cases smell a disintegrated tire . . . . and you still can. TPMS is great, I plan to own one some day. But if you’re aware and master of your trailer towing domain you will know when you lose a tire. This person was not master of their trailer towing domain and drove on a flat tire for miles.

And as to why they kept it mounted: why not? You’ve got to put is somewhere! The wheel is probably as valuable as the tire if it will still hold a seal. And with supply chain issues today it may be months to get one the correct size, let alone matched to your other wheels.

Wouldn’t it be better to be warned after losing 5 to 10 psi so you could stop in time to save the tire? I don’t think that waiting till tire failure and damage to the RV is a good plan.

What a dumb story. Guy had a flat, changed it, put the rim back on the spare holder until he can get it replaced. End of story. The rest is pure fluff and a waste of space.

and if the tire was under warrantee he had to keep it to show the dealer or no warrantee.

I had the same reaction. I had a blowout, mounted the wheel on the spare tire mount because it smelled! Didn’t want it in the TT.

Anyone notice the label above the taillight? Maybe a rental trailer, then needed to return the rim to the owner.

Thats definitely flat. Looking at the second picture & there is something sticking out on the ground behind the right tire. Weird, as it looks like it could be a drive shaft, also the end of it looks rusty!

What you are calling a driveshaft is actually his stabilizer jack.

We had a cap blow off one of our trailer tires years ago. What was left looked like this, and we mounted it on the rear of our trailer in place of the spare we took OFF the back. It stayed on the back of the trailer for a couple of days when we got to the RV park where we were staying while I priced new tires. We made a joke of it to passing walkers who asked what happened. I told them it was a new “anti-theft” project we were working on.

I think it’s supposed to be a joke. Where are the trailer plates? Also look at the stickers on the back, and all the hand prints. What’s up with the sticker with numbers about the taillight? The wheel looks new. Maybe the guys owns the service station, and this is way to advertise you to look at your tires while getting gas?? Just some thoughts.

Hasn’t it occurred to anyone this might have happened a few miles down the road and they just haven’t got to a tire store to have it replaced? Where do you suggest they carry it, in side the trailer?

This was my first thought exactly. You still need the rim.

This is a good time to check your spare, you do have one? Bought a used RV, dealer installed 6 new tires. Never did look at spare. Lost the spare tire cover on rough roads. Spare was the original tire from 2011. Had about 9 years “cooking” in the enclosed compartment.

I’ve seen a few comments already about why is it that the carcass is still on the rim, my answer is at least these people aren’t throwing it on the side of the road and waiting till a place where it can be properly disposed of

That’s a pretty fancy rim for what looks like a travel trailer. I wonder if their tow vehicle had the flat and the trailer used the same size tire and rim. Maybe they had a tow vehicle like an SUV without a spare.

Also could have been a tire on their toad. That wheel definitely does not look like it belongs on a trailer.

It’s just a basic aluminum rim. Why can’t it be on a trailer? Some of you folks are pretty judgemental. You don’t know what the rest of the trailer looks like. A couple of aluminum wheels and a steel spare don’t cost that much.

I think it was driven on flat for awhile, like Roger Marble said. They finally changed it but couldn’t get the shredded tire off the wheel, so just mounted it there until they could get a new tire put on the wheel. Sure makes a good “conversation piece” in the meantime. 😀 –Diane

I agree about they mounted it till they could get where they were going. The part about driving on it may not be true. Just yesterday we had not one but two blowouts while traveling from TX to TN
One looked shredded and we stopped as soon as it blew. One had a piece of construction debris and other who knows. We had to drive truck and get two new tires. One for second blow out and one for the spare. Oh and we were 70 miles till home.. Don’t always assume someone drove on flat.

Thanks, Lisa. Yeah, it was just a guess on my part. Sorry to hear about your two blowouts! Wow! But I’m glad they didn’t cause you to wreck. Take care. 🙂 –Diane
