Replacement Tires

[Cummins12V98]

Let's just say your guy is full of "Barbra Streisand". He did have some info that was true on the ENDURANCE.

I did a search and the only mention was a couple times on forums a couple years ago. The tires are still sold and available.

GY ENDURANCE available tires now for 2 2/3 years.

Thanks for the reply.

That BS Goodyear story has been around for years. At least since 2016. And your GY dealer bought into this?

Had Goodyear G614's on mine. Just put a set of Sailun's on mine and very happy. Higher speed rated and running less pressure in them per inflation chart. Got mine through Walmart.com., but they come from Simple Tire. Free shipping to my house. Had Discount Tire do install. Walmart has them at $132.00 a tire right now. https://www.walmart.com/ip/Sailun-S6...Tire/430853805 Price will vary daily so keep checking their site. I have saw a low $114 a tire to $154 a tire.

What did Discount Tire charge for the install?

$20 a tire.

Stories start and even the managers get caught-up in the frenzy.

Let's look at a fact that could have started it.

In the RV trailer industry the G614 is commonly found on vehicle certified 7000# axles. When the new 10% reserve load capacity above vehicle certified GAWRs was introduced by RVIA, 98% of all USA trailer manufacturer's were effected. Applying that 10% recommendation would make the G614 ineligible for OEM fitments on such 7000# axles. Goodyear loyalist consumers would want another qualified tire from GY and that tire could be the Endurance ST255/85R16 LRE.

Here is a clearer pic of the ENDURANCE options.

VERY intersection the G614 RST "G" at 110psi capacity is 3,750# and the same size ENDURANCE 80psi capacity is 4,080#.

Look more closely, the Endurance is larger and using TRA standards for building ST tires. IMO the G614 RST has always been a bastardized LT tire, hence, a Regional Service Trailer tire. 98% of the RV trailer industry will no longer use them on 7000# axles because the do not meet the 10% load capacity reserve criterion for those axles.

Now I see that! But the same size tire is listed at 110psi for a load of 4,400# unless it's a typo???

At 80-psi they are rated at 3,640# "E" 80psi VS 3,675# "G" 110spi.

The chart is correct. It just needs to be updated as new tires have been introduced since it was printed.

When Sailun set a new standard for ST tires with their ST235/80R16 and ST235/85R16 steel cased tire they got a firm grip on that portion of the ST tire market. Since then, numerous "off shore" ST tire manufacturers have entered into the competition in that section of the market. New steel cased sizes are being introduced almost monthly. Below is a listing of some of the manufacturer's I've been tracking.

The following all produce steel cased tires in sizes ST235/80R16 LRG and ST235/85R16 LRG.
Sailun -- BlackLion -- Gladiator -- GreenBall -- Carlisle -- Hercules .

The Discount Tire Store brand Heartland, comes in size ST235/80R16 LRG.

Two have ventured into the 15" market with steel cased ST225/75R15 LRF tires. (3195# of load capacity at 95 PSI).

Hercules & GreenBall.

Another innovation without, steel casing, is the all new to the market tire designed with durability features for those off-road adventures .. It's the ST235/75R15 LRC with 2340# of load capacity at 50 PSI.

Because RVIA is pushing very hard to get all bias ply tires off the RV trailer, Kenda has - and this is the correct size - a 12" ST145/R42 LRE radial with 1540# of load capacity at 80 PSI.

If it's true the GY G614 is going out of production, I hate to hear it. I've run those tires on both my Cedar Creek and DRV 5er's and never had a single tire issue. It's the only tire I would consider as a replacement; however, if they are to be discontinued then I'll need to consider an alternative.

Dutch, if you can still get a set of G614's, I'd recommend doing so.

[Cummins12V98]

I had great luck with two sets of GY G614's. Looks like they are still available, Discount Tire and Simple Tire about $282.

[Notanlines]

Tenbrooks, did you read the posts? You're buying into an old wife's tale....

should you run max air in a tire if you don't have max weigh on it?

[Cummins12V98]

NOPE!!! Per GY Tech Support know your tire weights, use the weight/inflation chart for your tire and add 5psi to what the chart says.

Do so and you will have perfect tread wear, better stopping and ride.

Exactly, but getting your 4 corner weights can be a challenge, but the most accurate way to know what each tire is actually carrying.

[Cummins12V98]

Go to your local scales along the interstate when they are closed. Plenty of room for doing so. Use the heaviest tire per axle to determine psi for that AXLE.

Their steel cased RV trailer tires (ST) have a very good reputation. Probably because they have not been used as OEM.

Here is a reference with the four different ST sizes, one 15" and three 16". Note that the most popular 16" tires have a minimum wheel width of 6.5".

You know when that commercial policy is used, almost all of the tire's load capacity reserves are not used and they are desperately needed for RV trailer axles. The best method is to follow the trailer manufacturer's recommendations.

Not sure your point. I posted EXACTLY what GY tech Support told me to do if wanting to use the Tire weight/inflation charts instead of BLINDLY running MAX inflation.

This is for up sizing load range or if you have a RV that has PLENTY of tire capacity to run less than MAX.
