We bought it used and tried a long trip from Houston to Phoenix and then back thru El Paso, diverting toward Big Bend before the final stretch back home to Houston.

We had a tire blow out near Marfa, TX --> Middle of No Where! We had a sliced hydraulic hose, destroyed wheel, destroyed fender skirt. Counting RV Tech and replacement parts, it cost us about $1200.

Hi Spec Warranty Dept, promptly sent me a new tire and rim and they were easy to work with.

We are leaving in 2 weeks on a 6000 mile trip from TX to Glacier NP, Yellowstone, and Grand Tetons....and yes we decided to upgrade. Almost went with Sailun, but decided on the Trans Eagles.....
This is not intended to be a rebuke of any sort. I just want to get a recommendation on record and it's about this situation.

No matter how well tires look on the outside they may not be telling the whole story. Used trailers of any age are suspect for damaged tires. At the very minimum, I recommend having the tires inspected internally. The inner liners are going to show damages not being able to discern from the external inspections.

Tread wear and mileage are poor indicators for trailer tire conditions. Trailer tires age out. Age is not common from situation to situation. Tires that sit around underinflated/overloaded degrade and age much more rapidly than tires properly inflated and used regularly.

All the above is true....it is up to each person to know and understand if their tires are safe and up to par for the rig they haul. One would have to write several pages in order to cover all the variables and factors related to the subject of tires.

-we just purchased an Avalanche 312RS and I'm looking for a load rating chart for air pressure.
Do you have a load inflation chart?
Thanks

There is no "built in reserve capacity" with ST tires like there is in LT tires.

Load capacity is based on air pressure (not ply rating), so it's the air that gives you the "ability to carry more weight".

All manufacturers of travel trailers take that into account when fitting specific tires to their trailer. The recommend tire pressure placard on the front right of the trailer should be followed.

Is there a reason you don't want to tow at recommended pressures???

I believe you would consult both the label on your rig as well the #'s on the tire themselves. Use the MAX PSI rating to ensure the tire walls are at their strongest to prevent blowouts when you inevitably hit a pot hole going 50 mph plus.

The intent was to have HiSpec refer me to their load rating chart.
Thanks

HiSpec doesn't monitor this forum.... You might try their website, at the bottom you'll find a "Contact" link. http://www.hispecwheel.com/contact

Good Morning,

I have attached a sheet to give you some general information on ST tires. I hope this answers your question. If not we are happy to help any way we can.
(Please note that it is recommended to try to keep your tires at the pressure listed to archive the best performance from your tires.)

Two flats/ one day

We have traveled about 20,000 miles in our 2020 Laredo with HiSpec 225/75R15 117M Load E tires. Yesterday we had two flats caught by our TMPS. First flat we had stopped for lunch and returned to an alarming TPMS. Installed the spare.
At 9pm, TPMS alarmed on slow leak. I could hear the air escapingwhen I investigated.
First tire was a cracked stem.
Second tire was a partial delamination of the tread requiring replacement.
Manufacture date is 1919 - 2-1/2yrs old
I haven't contacted HiSpec yet but I'm looking to replace all tires.
My history with tires is once one starts tread separation the rest are close behind. I've had similar issues with a Chinese OEM tire and Hercules tires. I'm looking at Goodyear Endurance tires.

We use Carlisle Radial HD Trail in the same size as is on your camper and I am on my fifth or sixth set over the years. Perhaps Goodyear Marathons come to my mind when I consider spending the extra for the Endurance.

Welcome to the forum.

The cracked valve stem you can't blame on the tire. I have the same size tires and replaced my OEM tires over 5 years ago with Carlisle Radial Trail HDs. Don't know the miles but typically they age out before the tread wears out. Personally, I'll be replacing them next spring with the same tires.

Thanks. I'll look at Carlisle tires.
The attend will be replaced with all steel stems. TPMS recommended steel. Mine were steel on rubber base.

Can you link the forum?

I just purchased a 2022 avalanch with Hi Spec tires and want to research what is happening with these tires. Thanks!

Because the Chinese ST tire manufacturers have no problem changing molds for brand names, a lot of USA wholesalers want a name recognition. Hi-Spec is a well recognized wheel provided and they may have wanted tires to match their wheel name.

To investigate who the real builder of the Hi-Spec tires is, you can get the manufacturing plant code off the tire. Part of the plant information will have the tire manufacturerís name. You may be surprised to find that they may manufacturer more than a dozen brand names from the same molds. And thatís one of the primary reasons I donít like to get involved with name brands.

Because they use the same mold does that equate to the tires being the same? It's common practice in all forms of multi-brand manufacturing to make a product to the customer specs, not just a difference in labels. So while the outside may look similar or even identical what's inside?

Nobody knows. Those materials are confidential.

I would speculate that Hi-Spec is not in the tire business, just using tires they have ordered to standards just like other non tire building wholesalers.

IMO, the most important subject about foreign tires, is, who does the testing. The plant builder, or a 3rd party of their choosing?

Don't forget, I do a lot of reading.

Glad to know you're an avid reader, so am I but not about tires. The point is, your statement "...You may be surprised to find that they may manufacturer more than a dozen brand names from the same molds..." may lead a "lesser read" person (on the subject of tires) to assume they would be the same.

Good Afternoon,

We at HiSpec want our end-users to know that we stand behind our tires and wheels, if you are having any issues with either our wheels or tires, please contact us at [email protected]. HiSpec does not use a house brand mold for our Oracle or Sonoran tire brands. Our team of engineers designs all of our wheels and tires in our Indiana facility where we have an onsite test facility and use third-party testing facilities for our products. We strive to provide safe reliable products yet at some point issues will occur and we try to handle issues in a fair responsible way to the end user.

When made at the same factory/plant and having identical tread patterns we just don't know if the internal structure materials are also identical.

But, the bottom line here is name brands, how important are they? If they or their builder has a history of defective recalls, raised eye brows. Otherwise, it just may boil down to anecdotal information. Flip a coin.
