Tires for a 2024 Minnie 2500FL?

[machunt]

We have a 2024 winnie 2500fl. currently we have st2257515 endurance tires on her. Alot of mixed reviews as to the dependability of these. I believe 8000 lbs is max weight for rv. we are makeing a 4000 mile trip and want to put odds in my favor of no blow outs

I'm not familiar with your type unit but the tires aren't aged out for sure. You read a lot of BS on forums about tires in particular and I try to ignore most of it., however, when it comes to feeling uncomfortable about something, I usually try to remedy that. A blown tire can prove very costly.

Just to clarify, you have 2024 Minnie (not Winnie) and the tire size for your travel trailer is ST225/75R 15E.

The axles are both 4,400lb rated and the gross weight of the trailer is obviously 8,800.

Goodyear Endurance are made in the US and are about $180 each and Hankook Vanstra tires are made in China and are about $120 each. People like the Goodyear's and I hear good things about the Hankooks, as well.

I see you mentioned you have "endurance" tires I didn't take that to mean Goodyear Endurance tires. But perhaps you did.

But unless you've traveled a LOT of miles since 2024 I'm not sure what benefit you'd get changing them now???

I know these goodyear endurance are poly carcaas. was wondering if there was a steel carcaas/

Here's how Discount Tire describes the Goodyear Endurance ST Tires:

Its enhanced inner liner provides extra air loss resistance and its sturdy internal polyester construction (reinforced by steel belts) helps increase your trailer’s hauling capacity.

I think this combination of GVWR,GAWR' s give almost no tire related failures.
Most TT have axles and tires, with yust enaugh capacity to law , so need full pressure to carry the loads.
This is where the general rule of max pressure of tires for TT comes from.

But some exeptions I found .
Airstream and OutdoorsRV, who have comfortable reserves in axles to the GVWR, and comfortable reserves in tires to the GAWR' s .

I found 225/70R15 in D load R speedrated with only 1 loadindex step lower then the 113 of ST225/75R15 D load in the goodyear list. So that 1 step is explained by /70 instead of /75.
So the maxload of this size is not 6 loadindex steps upgraded to LT, because of lower speed, as most 16 inch ST are done.

So the 2830 lbs maxload/ loadindex 117 for E load used for your TT, dont need to be derated for speed. So 2830 lbs maxload AT 80 psi have comfortable reserve to the GAWR's of 4400 lbs each 5660/4400= 28% reserve, so comfortable enaugh.

Both axles together can theoretically carry the complete GVWR, so reasonable reserve, (not comfortable), because 10% on hitch is minimum to law in US.

For those reasons I expect that you can leave these tires on your TT, and wont have tire related problems in the years.
A pucture can always happen.

Mayby I can put the Minny Winny in the exeption list with Airstream and OutdoorsRV.
Mayby the larger Winebago's have less reserve.

So your concern about the tires is based on failures on most TT because of to poor reserves. Your TT and tires are the exeption to the rule, so no failures to be expected.

1 STOP GUESSING
2. You need to read your certification label to learn the MAX load it can be
3.. With the RV loaded with as much stuff as you ever expect to carry (full fuel, water, tools, cloths toys etc Get on a CAT scale and learn the facts of how much you weigh. Hopefully your axles come in at no more than 90% GAWR
4. Confirm the MINIMUM inflation required to carry the load you have. ou should run with at least a +5% on that minimum inflation

Given that over half of RVs are overloading their tires I think its reasonable to feel that many of the reported tire problems come from overload/Underinflation.

Stop guessing

If you are 100% certain you NEVER ran with inflation LOWER than specified in the GY Load/Inflation charts you should be good.

Do you run a TPMS?

You should.

I do not think any GY Endurance ST tires have Steel body. Very unlikely in a 15" tire. Steel body, in itself is not going to prevent a failure if you overload and underinflate your tires.

not a fan of tpms. by the time you get a warning prob to late

Yes, it is possible to have a tire failure due to "Belt Detachment" and not receive any warning, as TPMS are designed to warn of a loss of air and Belt Detachments do not manifest with air loss. Belt Detachments develop over 1,000's of miles and can be discovered if you do a "Free Spin Inspection" at least once a year after year 2. It's like complaining about a blood pressure test not identifying a broken leg.
