What happened exactly to this tire?

Google Plug Patch. This is what we use, recommend by tire mfgs. It's a patch with a plug in the center, must be installed from the inside, plug pulled through to the outside. The plug fills the hole and helps keep rocks and water out, the patch seals the hole, keeps air in. The first thing that should be done when patching is to use a liquid buffer-cleaning fluid and a scraper to clean the silicone release agent from the inside. If the tire is buffed before this is done the silicone will be buffed into the rubber and the patch won't stick.
I remember seeing the "Speedy Plug" brand of those at the Dot shops. They used them on our tires if it was just a nail hole.
The state got what they always thought was a good deal on Goodyear Wranglers. 20,000 miles tops on vehicle I was driving.

Well I keep the local tire shop employees supplied with Ghost peppers and carolina reapers when i have them so when they see me coming they run out to see what i need done. 1 of them just said, "old tire". and that was the response I got when I ask what happened.
40 bucks for a used spare tire and to get my 2 tires mounted and balanced. Yep.I balance trailer tires so I don't have the vibration and the wear and tear on the bearings.

Several things come to mind. Tires over 5 years old, insufficient pressure, wrong speed rating, and mis matched sizes/brands.

I had a tire delaminate on my trailer last year. pressure good, tire about 8 years old. Entire tread came off, nearly ripped the fender off with it. No slapping, just BOOM, and it was off and gone. The tire stayed on rim and did not deflate. I was on my way home from Jacktown, On I-80, and the tire came apart on the Hackettstown hill, about 30 miles from home. After pulling what was left of the trailer fender off the tire, I drove home, keeping under 40 MPH. I didn't have a spare. Drove home on the steel belts, then another 20 miles to my sons shop, to get a new pair of tires. The other tire still looked good, but I pulled it off anyways. The tire never did go flat!

I was told that true trailer tires have a better sidewall design than auto tires, and need more pressure to take the loading required. Most auto tires only take about 30 to 36 PSI - which makes the sidewalls flex and build heat. My trailer tires take 45 PSI, and are 8 ply rated.

"I'll never go back to that store again!"

Yeah, but those guys probably will be fired from the shop, so when you go to the next place, you'll see them there instead!

My 1989 Mazda truck has three of the four tires date coded 1989. A bit checked, but seem to be fine. I do limit my speed to 55 - 60 mph however.

I have found that the newer the tire, the shorter the lifespan. On my 1964 Ford I have all bias plies, including, gasp, retreads on the back. Our climate here is cooler and wetter than most however, which I think greatly helps rubber life.

I have had three tire failures on cars over the years - all on radials, and newer ones at that. None was dramatic, the cars just pulled hard to one side so I pulled over. Probably the reason trailer tires fail so dramatically is because it's harder for the driver to feel when the tire starts to fail.

The tire compounds in todays tires is way different than those made years ago. yeah, they fail more quickly, after all the tire companies want to sell tires!

I bought two Carlisle ST rated tires for the trailer. Sorry to say Chin made. $73 each mounted and balanced by my local tire guy.

*FYI Most Goodyear trailer tires were made in Chin but due to bad reputation they brought production back to the states last year. $140 each for them.

Tire compounds have changed , my friend said due to the EPA off gas rating of new vehicles. I know we are talking trailer tires here . my 25 YO carlisle tires on my car trailer show no issues , but I doubt I'd road them today.
now my 4 YO marathon ST trailer tires blew out , one did just in the yard !!.
friend said speed plays a part in trailer tire life ,along with age, fixed sitting position, inflation. I did buy some china bias ply tires , GAWD they stank for a year outside !! still running and working 3rd year now .

overall not to happy with prices or choices and lifespan :mad::mad:

In Memory Of
During my brief stint of work at a company owned Standard Oil gas station, I was told that NO tire of ANY type was to be plugged. Cold patches were used.

This was back in the late 50's when tubeless tires were fairly new. Of course, all tubes were patched.

Tubeless tires were dismounted, the area around where the patch was to be applied was buffed then washed with gasoline. After it dried, the "glue" was applied and allowed to get tacky then the patch was stuck on and thoroughly rolled into the area. We never had one come back.

I never let a shop plug a tire for a car or trailer. It's getting hard to find a shop that will patch a tire or even has the stuff to do it.

We were taught that a plug, unless it is absolutely centered on the hole, will leak air into the sidewall. Plugging also damaged more of the cord.

Having said that, I haven't had a flat for years. Now, I'll mention that we had a motorhome that suffered several blowouts, all with tires that were properly inflated. Different brands, even the highest pressure/load rated ones would just suddenly explode. I think that was caused by something wonky about the chassis, although for as long as they lasted, the wear patterns were normal. Those tires always ran hot!

Tire heating is caused by 3 things. 1) most important - improper inflation pressure. low pressure causes heating in the sidewall. that will cause either thread separation or sidewall failure - a blow out.

2) too heavy a load. An overloaded tire will fail without warning. Check load rating and weight you actually have. A ford 350 with a heavy camper weighs a lot more than an MT truck! many people overload their trailers without recognizing it. "The tires look OK" does not mean that they are overloaded! When I bought my single axel trailer, new,, the load plate stated 3500GVWR. When I looked at the tires, they said 6 ply, 1100 max load on the sidewalls That meant that the tires were only good for 2200 pounds. That's 1300 pounds under the trailer load rating! :eek: I now use 8 ply 3600 pound tires.

3) Another thing to note - do not use passenger car tires or certain low weight truck tires on a trailer! The sidewalls are constructed differently for trailer tires, to deal with the stresses generated during turns, especially on multi axel units. If you do not have manufacturers ratings needed, see a good trailer shop for recommendations. I said "A GOOD SHOP". Not a box store.

Although not a trailer, I bought 4 new tires from Costco for my dodge ram 1500 pick up. it was equipped with a towing package and a V-8 engine. I had all 4 tires installed, with new stams and valves. All tires were balanced at installation. Within 2 months, I blew out 3 tires! The first, I thought was just a fluke. the tire shop made good on it. The second pissed me off, as it blew 2 days later. the shop tried to tell me I hit something, and that's why the tire blew. I asked the shop manager to show me where the tire was damaged so it went flat. he could not. As I was driving the truck out of the shop, the 3RD tire blew, right in the shop!:eek: scared the crap out of all the mechanics (me too!!). I then asked the manager "So - what did I hit now?" no answer. As he looked up another tire, he asked me "Did you order those tires for your truck?" "No, I brought it in to the shop and the tech looked them up and recommended them." They were installed right here in this shop, not more than 2 months ago, I still have the original receipts in the truck." his reply "the reason for the blow outs are that they sre the wrong tires for the truck. They are meant for the light weight, not for the full sized truck." "So now what?" I asked. Since it was their screw up, they finally made good on the proper tires, AFTER I threatened to sue them. Their failure to install the proper tires to begin with actually threatened me and my family. What if one of those under rated tires blew at 70 MPH, with a trailer in tow? the result could have been a horrific accident. BE AWARE of the tires you use!
