exploding tire

[Beaker]

Well, I joined the blown tire crowd over the 4th holiday.

I had just installed a TST monitoring system and within 120 miles, tire exploded. As the monitoring system was new, I was watching tire pressures and temps closely, nothing unusual when the tire blew. Was luckily near a closed rest area, pulled over quickly, and changed tire. The tire did some damage but I have repaired it.

I have had flat tires on cars before but not on a trailer. This thing just exploded; don't know if the tire went over anything or just blew up. Just happy it happened where it did.

Was glad I carry a 12 compressor with me because the spare only had 20 lbs in it. Although the compressor takes a while it is nice to have.

And before you ask, 225x75 15 ST, about six years old(mfg date 08).

On return trip while accelerating on the on ramp, a truck with a Cardinal fifth wheel let us in and quickly disappeared down the road. About 20 miles later, saw pieces of tire on the road and the Cardinal pulled over a little bit down the road with the left rear flat. He was just onto the shoulder with his left wheels on the shoulder with no more room to pull over at that section of highway. Hope he made out alright.

Consensus says Maxxis E-range is likely your best bet for a 15" ST tire. I've not seen anything about the newer Carlisles, though, which is what I ended up with, though I wanted the Maxxis. Given that the Carlisles have a 87 mph speed rating, for an ST, that's saying something. YMMV...

You better recheck that speed rating with Carlisle. I think they are no longer playing the bass boat shell game. All ST tires have a 65 MPH speed restriction, that is how they get here inflated weight ratings.


From Carlisle's web site:
Best Practices
– Any tire, no matter how wel constructed, may fail when in use because of punctures, impact damage, improper inflation, overloading, or other conditions resulting from use, misuse or neglect.
– High speed towing in hot conditions degrades tires significantly.
– Best practice. Do not exceed 60 mph while towing a trailer.
– Most ST trailer tires have a maximum speed rating of 65 mph.
^^^^ Did you miss this one, Chris?

– Load carrying capacity decreases as heat and stress generated by higher speed increases.
– Time and the elements weaken a trailer tire.
– 3 to 5 years is the average life expectancy of a trailer tire, regardless of mileage.
– It is estimated that in approximately three years, roughly one-third of a tire's strength is gone.
– After three years, depending upon storage and conditions of usage, consider replacing trailer tires even if they have tread depth remaining.
– After five years, trailer tires should be replaced in al cases

CYA policy, Chris, just as any tire company that sells Z rated tires tells you to obey all posted speed limits, or U-Haul's 45 mph max stickers on their trailers. You go over 45 mph towing a U-Haul trailer and have a blow-out, you pay for a new tire; you go over the posted speed limit in your Corvette and lunch a tire, so solly, not our problem. I'll have to check my tires when I bring my FW out of storage in a week, though Discount shows them as a N speed rating, which is 87 mph.

seetweil is right. I forgot about the high and low pressure setting that will set off the alarm as well as the fast leak alert that sets off an alarm. I just read the manual 3 weeks ago and already forgot some of the most important information....I like the system even more now! I hate getting old 😞

the sensors themselves don't know anything about the alarm settings, so my opinion is that they broadcast their info continuously, and the monitor is the one smoothing the info display

I agree on the getting older part..

[NC_Hauler]

Agree with Chris, I've not seen an ST rated to 87 mph, not a Carlisle...normally Max for some of these ST is 65 mph....which is about as fast as I want to tow one, get good mpg and be safe.

I was running I26 yesterday evening coming home from work and a 1 ton SRW Superduty was towing, what I perceived to be about a 35' Montana...speed limit on that part of I26 is 60 mph, just before it merges with I40 in Asheville...I was running about 63 mph and he went by me almost like I was standing still...was almost out of sight before I knew it....had to have been going 75 mph at least, I ran up to 70 for a bit and wasn't catching him....that's scary...Just don't understand what the hurry is..:h

I'll have to look into seetweil's comment on the over ride. That would be good and makes sense that it should.

[Beaker]

They are not perfect. The fault with it is that the sensors only transmit pressure and temp EVERY 5 MINUTES. (Page 2 of Instruction Manual)

I will have to check my manual in the morning. My system is new and I was watching it quite closely and was not taking 5 minutes to show changes in psi and temps.

It may have taken 5 minutes when first turning the system on.

Thought it was a bad monitor at first.

Sounds like OP had sudden total loss during the 5 minute where no signal was being sent.

the TSTs override the cycle on quick loss of pressure, and transmit immediately (least mine does)

to test, get the readings and unscrew a sensor..

Much depend on if you need a C/D or a E 15" tire as their isn't much of a selection in 15" non ST tires.

There are several brands of LT235/75-15 C at 1980 lbs capacity.

Goodyear Wrangler HT in a LT215/75-15 D load range at 2095 lbs.

Maxxis has a commercial U-168 Bravo in a few 15" LT up to 2337 lb load D tire.

A all position Vanco 2 in a few 15" sizes up to 2470 lb D tire.

Yokohama has a RY 215 for commercial operation in a 700R 15 D tire at 2040 lbs capacity.

Your wheels need to handle the pressure rating of the tire your going to use and have proper clearance .

The ones on it now are 225/75/15 LR-D

Whichever tire brand you decide upon, this is worth a read ST to LT.
