Anyone know where Hercules tires are manufactured? They have a G rated tire that seems to be comparable to the Sailun's. I know they made by Cooper but wondering if made in the US or overseas.

Just so happens I know one of their Plant Superintendents. I'll ask my son. He is at the Findlay Plant. If he is slow to respond I will see him right after the Rally.

He keeps playing the 4 kids and crazy hours card for slow responses.

Had them on a tag along, rock solid.

Used frequently by ranchers out here and I've had them on a truck years ago. They're a tough tire, but at least the truck tires were stiff and did ride rough. On the other hand, the Sailuns that came on the new rig seem to ride rougher than the 614's on the old one. Not a good comparison since it's different rigs, but it's all I've got.

I've run Hercules tires on my dually … they're a bit stiff, but wear well.

Exactly which Hercules tire would you suggest? I need to replace the GY on my Montana 2013 3582RL.

I would suggest Sailun S637's , with all the great reviews why bother with another brand. I wouldn't think even price wise, without checking, the Hercules can compare to the Sailuns.

I'm running Hercules on our 2010 295RKD Mountaineer. Have put about 10K miles on them. Thinking I'll get another 10K miles before I need to replace them.

Trailer axle/wheel alignment is such a pain.

Is this a G rated 14 ply tire? Made in China??

Yes that is it. Over the last several years they have gave the members here great service. After the service they have gave and the price I donít see any reason to try anything else. Tires are one place I wont someone else test them for me.

They are, and arguably the BEST G rated tire for our fifth wheels on the market.

I know there are some that frown a little on this china made tire, BUT here is my take on trailer tires. My last set of G tires for my fifth wheel were the Goodyear G614's, they served me well, they had at one time, not the best reputation , but they have improved ,BUT at TWICE the price of Sailun S637.

I feel the price of a Goodyear G614 is outrageous, and no where near competitive , and I for one refuse to pay that kind of money for arguably an inferior tire.

Tire Description:
The Sailun S637 ST is an all-steel highway rib tire designed to provide the ultimate in performance for trailer applications. The heavy duty all steel construction delivers low rolling resistance, superior strength and durability while providing sure-footing and straight tracking. The S637 ST is perfect for all high load capacity trailer applications.

Features & Benefits:
All steel construction for maximum strength and load capacity.
Multi-sipes improve traction in wet conditions and dissipate heat for prolonged tread life.
Five rib design for improved stability.
Solid shoulder to resist irregular wear and improve fuel efficiency.
Requires special high load capacity wheel. Consult wheel/ RV manufacturer for proper application.
This is the size tire I have on now so I would guess I would go with this same tire: S5541960 ST235/80R16* 129/125 L 14 10 6.50 30.8 9.3 14.7 4,080 3,640 110

But what does it mean by "requires special high load capacity wheel???
Also the current goodyear marathons that came on the fifth wheel have a PSI of 80 these say 110? Does this make a difference???

Kelly,

To get the full benefit of the G rated tires you need wheels and valve stems rated for 110 PSI. You can run them with 80 PSI wheels but they will have less load capacity. Your wheels should be marked on the inside. I believe Montana went to 110 PSI wheels in 12.

I am pretty sure your wheels are rated for 110 psi. I wouldn't mess with any G rated tires other then Sailuns, they been out now for several years, with great reviews.

Check your wheels on the backside, pretty sure you will see the 110 psi rating. Simpletire online is probably your best buy, and free shipping.I bought mine locally ,and got a price match from them. So out the door was the same as Simpletire, and then paying to have them mounted ,and balanced at some tire dealer .

I believe all recent Montanas come with 110psi wheels. If you're going to change over to load range G tires running 110psi, better make sure you check the wheels first.

Ok. Thanks so much for the info. I am a tire/wheel dummy but I am learning. Knowledge is power. If you have a cardiac issue I can fix you up but wheels and tires are another beast.

Ok so I know I need to check the wheels to see if they are 110 PSI wheels so can I do that with the existing tires on or do they have to be removed? Will the valve stems note the PSI as well? Can the valve stems be changed if the wheel is fit for the 110 but valve stems are not??:blush:

Kelly,

There is no need to remove the tire from the wheel to check the PSI reading - it should be stamped on the inside of the wheel. For valve stems you should have metal vice rubber stems. Metal stems can be installed on an 89 or 110 PSI wheel.

Yes you will. My 2014 HC did not have a stamp on the back. I was told by Keystone they were 110PSI but I donít believe them. I had 80 PSI tires. I switched to the Saliun and run them at 80 PSI. These are heavy tires and probably over kill for my RV. But I am scared to death of a blow out. Side note. I had less than 10K on the other tires and they found a bulge on the inside of the tire I never saw.

If hercules has anything to do with cooper, forget it. My local cooper dealer doesn't even recommend cooper tires, and for good reason. If tires are regularly compared to goodyears, there is a reason for that.

Maybe his profit margin is less on the Coopers. Although not exclusively, I have run Cooper tires for many years on pickups with ZERO problems.

Ok so what about that stamp on the side of the Montana just under my Lippert level up system that "Tire and Loading Information"? It tells you the tire size and cold pressure which says "ST235/80R16E" and 80 PSI! Does that mean that 80 PSI should be all I run on the Montana? Still have not located that PSI stamp on the dang wheel! It also says the weight of the cargo should never exceed 3330 lbs. This is so confusing. I normally just pull up the the tire dealer in my SUV and ask for tires and they put them on. This is ridiculous.

The label you refer to applies to the FACTORY installed tires on your specific unit and does not apply to any tire upgrades you may do. Our 2012 3585SA had 110 psi wheels.

You need to verify the the psi rating on the back side of the wheels, one of your four should be rotated to where you should be able to see it, take a flash light, and get under there ,and take a look .

The 3330 is given so you don't exceed your GVWR ( Gross Vehicle Weight Rating ) You have a dry weight plus this 3330, which is your GVWR, which I would guess around 16,000 LBS. So your actual trailer weight is around 12,500 before its loaded.

You have to divorce yourself from anything you've previously known about tires. Nothing about P-metric or even Light Truck E-rated tires for SUVs applies here.

The example ST E-rated tire from the placard carries a max psi rating of only 80, as are all E-rated tires. Put more than 80psi in and you'll blow them up or exceed the wheel rating, and yes, wheels can crack. What does that mean with respect to the placard, provided by RV mfgr.? All it means is the RV mfgr. reviewed the tire mfgrs. specs for that tire and has determined it can carry the load it has computed on the axles, plus your stuff at 3,330lbs. They can say they did their due diligence, and any failure is then on the tire mfgr.

The problem with ST tires, until very recently, has been cheap Chinese knockoffs that are not tested to US standards since they're not intended for passenger use. The result has been a significant number of failures with damage to RVs, busted vacations and increased driver stress.

Let's take a 14,000 FW as an example. With an avg. 20% on the pin, you're left with 11,200 on the axles (14,000-2,800). Dividing that 11,200 by 4, each tire can carry 2,800lbs. We're still within avg. E-rated tire specs (3,500-3,700lbs), but let's throw in the 3,330lbs of your stuff, 833lbs each, so each tire is now carrying 3,633lbs. Oops.

Until very recently, KS and other FW mfgrs. have installed the most minimally rated tire, which I'm sure is related to their bottom line.
Coupled with a poor tire, it's a recipe for disaster.

So, what to do? If you have a heavy FW, it certainly can't hurt to upgrade to a good, ST G-rated tire, and 110psi wheels. It may be, at your weight, you don't have to use max psi (using the tire mfgr. load table). The Sailun has proven, at least anecdotally, to be a winner. The GY Endurance is getting good reviews, too. There are a handful of other ST tires being talked about positively (Hercules, Cooper, etc.), but their track record is not proven, IMHO. Hope this helps.
