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.)
