Question Tire Blew Today on the Highway

We were heading home from Gulf Shores, AL to Texas Today and I blew a tire on the highway at 65-70 mph.

Anyone have an idea why this blew based on the pictures of the aftermath? Maybe someone can help tell what the failure mode was by how it looks?

Also, what’s the best route to getting it repaired? Insurance claim? Extended Warranty? Something Other?

I did triage repairs on the side of the road to get going. I didn’t want to wait all day for roadside, although we called into insurance roadside just in case I couldn’t get her done.

I’ve always been diligent with keeping them aired to 100 psi cold, max per the tire. Doubtful it’s overloaded, trailer has 5k pound cargo capacity and my last scale was around 10k on the trailer axels. 2-3k under GVWR.

I was just curious if this is a typical China bomb failure, or maybe it developed a leak in transit and the sidewall failed, or maybe it took a hit to hard on a bridge joint/pothole, etc.

Again, just curious what the tire experts would think caused it.

It looks like, from the first photo you posted that the blown tire is a Trailer King, 225 80R16. Your RV is a 2018, so the trailer may have been produced as early as March 2017, which means the tires could be as old as "late 2016/early 2017"... If you post the manufacturer's date code, located on the tire as a 4 digit number "branded in an oval", we would "know for sure how old the tire really is.

Using "worst case" that tire could be nearly 4 years old. It is also a "brand with a TERRIBLE reputation and is commonly referred to as "China Bombs"....

You are one of many who have experienced a blowout with TK tires...

As a "precautionary consideration" you might replace the other tire on that same side. When your tire blew, the "other tire on that side" was carrying "all the trailer weight" and was "critically overloaded"... It may have made it home, but it's only a matter of time before it "gives up the ghost"... It would be a "shame" to have your trailer repaired, have the blown tire replaced and to have that remaining tire "blow on the way home from the repair shop" causing the same damage again !!!!!

It's time to upgrade tires on all 5 wheels and go with something other than China Bombs.....

Good to know you realize you're towing on borrowed time. Looks like tread separation to me. May have been caused by low pressure and hot temps combining to create the failure. the tire experts on this forum will likely have a more detailed response to your question.
A new set of quality tires all round would be in order. Also I'd highly recommend adding a TPMS so if there is a tire pressure or temperature issue in the future you'll have sufficient warning to safely get off the road, hopefully before any catastrophic failure or damage occurs.
As for covering the damage, that will fall to the insurance company. Extended warranty will be worthless for this issue.

It is hard to diagnose from a picture, but it looks like the tread cords failed as opposed to the sidewalls. It is a factor of age and construction with a bit of road hazard thrown in for good measure. My friend was on a trip last year and he lost 3 out of 4 tires within 100 miles. All were about 3-4 years old, under the rated weight and were aired to required pressure.

Time for a TPMS system. Glad you're ok.

Definitely an insurance claim!
Also time for 5 new tires, yes replace the spare at the same time, it's the same age/brand as the rest. With a toy hauler I'd recommend Sailun G rated at the minimum & if you're independently wealthy the GY 614s G rated.

Looking at my picture the date code is “2617”, so about 3 years old.

Thanks for the tire recommendations. I’ll be figuring out the insurance claim and replacing all 5 tires before it’s taken out again.

According to your trailer's specs the OE tires are/were ST235/80R16 LRF. Maximum inflation for that size tire is 95 PSI. Should your vehicle certification label recommend something higher, you should inform Keystone so they can initiate a recall on that certification label and pay for the tires and all damages caused by the failure.

It's nearly a normal condition for large fivers to have a single tire overloaded, especially on a toy hauler. Without individual weights from some scales, you just don't know. Your failure is very reminiscent of a classic tread separation caused by tire overload or under inflation.

My recommendation would be to use the same designated size (ST235/80R16) as replacements and step-up to an all steel LRG.

Tire itself says max cold PSI is 100 PSI along with the tire label sticker on the trailer.

Where is the best place to look for replacement tires? I’m not finding a lot of good options for 235/80r16 on places like discount.com, tirerack.com, etc.

I see more tire options listed for 235/85r16? Could I run these?

Russ was on to this from the beginning. It was a Trailer King and by RV standards it was just old. They are trash tires, period. Just as was suggested, ALL your tires need to be changed including the spare. I also recommend the Sailuns.

OK, my guess. Trailer King has mistakenly used an old tire inflation chart for Bias Ply tires. Bias ply tires will have a designated size like this ST235/80B16. For a LRF their maximum inflation pressure is 100 PSI.

Let's look at this (as if) from a retailers stand point. To replace a LRF radial tire, the maximum inflation pressure is 95 PSI. Your certification label says 100. What's the retailer going to do? They cannot inflate a 95 PSI tire to 100 PSI.

If it were me, I'd do some serious homework on those tires with 100 PSI on them, if they are also described as being radial tires (ST235/80R16.

Complaints don't get to be official unless filed.

Tires without recalls can be from very bad to very good but not trash.

It would be a lot more accurate to post the plant code for unsatisfactory tire performance. It seems to be very hypothetical to say something about a tire such as "China Bomb" and follow it up with; "Sailun's are a great tire".

A trailer King recall reference.

your issue with your blowout was due to a very large toy hauler with E rated 10 ply tires made by the "Worst" brand on the road...

You should be running ST235/85x16 14 ply G rated tires.... go up from the OEM stock size because you will pick up a lot of load capacity..

Verify your rims are rated at 110psi by looking on back side of rim.. psi rating will be stamped there.. And install all metal valve stems

Sailun is what Id buy... but any 14 ply G rated ST tire will outperform and outlast the OEM Trailer king 10 ply tires

upgrading your tires will give you more headroom capacity for load and the 14 ply steel cased tires are ten fold better than any E rated ones

I would not consider GY Endurance E rated tire for your toy hauler... it will not last well either with your load

GY G614 tire is over priced and doesnt have the load rating the Sailun tires do... or any ST 14 ply series tire for that matter

Check out the Sailun S637 ST series tire and increase the size as I stated provided you have adequate clearance for
the slightly taller tire.... you should

Tire itself says load range F radial tire. Along with the tire label on the trailer matching the information.

I’m sure it’s a classic china bomb scenario.

How do I determine if I can safely upgrade and run 235/85r16 tires?

Yes, and hypocritical also! That's why I didn't use the term "China bombs."
I believe the main point we have tried to make for years is that Trailer Kings are garbage tires. Some owners are not believers. Good on 'em, and we're waiting for their tear-filled stories in days to come.

Just as a note.. a two day old tire can blow out from a fence staple...

My practice is new tires every two years... I've never worn a trailer tire out and never will... The price of 4 or even 6 tires is cheap insurance against the damage you just suffered..

I replace them and sell the old ones like clock work..

Just to provide a little information here.....the Westlake "G" rated tires are seldom involved in the "China Bomb" theory. Yes, the "E" rated as well as some of the "F" rated tires are very well known for issues like the O.P. has. The "G" rated Westlakes are actually a very good tire and if you do some google searching, there are not many complaints about them.

Obviously, as a preventive measure, alway check your cold tire pressure before travelling....AND use a good quality TPMS system to monitor the tires for both temperature and pressure.

Oh, something else I forgot to add when I posted originally. Even though the Westlake "G" rated tires are very good tires, they are usually priced more than a Sailun "G" rated or a Goodyear G614. Because of that, lots of folks, when it is time to replace the "G" rated Westlakes, go with the Sailun "G"
