Even though you physically have 2 7000# axles, I think Heartland has derated them to something around 6750#. The reference below is from a Heartland model very close to yours in GVWR and the axles are derated to 6750# ea.. The Towmax tires are rated at 3520# at 80 psi. But, other like sized ST...

Depends, most owners will just go with the OE rim marked for 110 psi not thinking about the rim size. If the OE rim is a standard 16x6 it should be changed to 16x6.5 because that's the minimum rim width for the S637 tire. It boils down to a personal decision. The tire manufacturer has listed the...

Have you had your trailer weighed? You may be in for a big surprise.

I think you should get a second look at the tire size. The ST235/85R16 LRE is rated at 3640# at 80 psi and would be excessive for an OEM fitment for 6000# axles.

In the following reference there is a picture of a normal size tire and another of the same size that is in advanced tread separation. It's amazing how far they will grow before they actually fail............(http://www.irv2.com/photopost/showfull.php?photo=27625).

The minimum rim width for those tires is 6 and and 1/2". TireHobby

I was at the RV show at Greenville, SC yesterdayroaming around and taking pictures. I thought this one of a certification labelon a Savannah Landmark would surely interest any prospective buyer. http://www.irv2.com/photopost/showfull.php?photo=27429...

I’m a little late posting in this thread. I’m just going to post the way it’s supposed to be. I know some will disagree but what I print will be from tire industry standards. The primary thing to remember when writing about tire pressures is they are set by the vehicle manufacturer, NOT the tire...

Probably caused by setting in the sun with water droplets in the tire. As the air permeates through the tire the water will follow and cause rot. Pretty soon, BOOM! You can service the spare with oil pumped nitrogen. No water, no rot. Or, rotate the tires with the spare in the rotation. TireHobby

Tires seldom give the appearance of “blowing out” without a cause. “Blow outs” are most often caused by some sort of road hazard. The appearance of a “blow out” can be caused by the tire being over loaded or under pressurized or both. The tire will get hot from the inside out until it starts...

I think you will find that your 7000# axles have been derated by the vehicle manufacturer to something like 6750# GAWR. Look on your trailer’s certification label to verify that. That’s one of only two ways the vehicle manufacturer can install any of the ST235/80R16E tires. The other way is for...

There may be helpful information in this link. http://towmaxtires.com/tires/Landing.aspx?application=warranty TireHobby

RV trailer manufacturers - like car manufacturers - will give you lots of information about your trailer but seldom tell you the specifics about how that information is applied. The published specs for your trailer lists your axles as 7000#. That's most likely a true statement. You can look on...

I see your new tire have the colored dots. Did the installers use them correctly? Here is the reference.....http://www.bridgestonetrucktires.com/publications/ra_v13_i1/PDF/ra_v13i1%20ask%20doc.pdf

A couple of footnotes: 1. The picture of the failed tire in post #1 is a typical example of a "zipper rupture" common to all steel cased tires such as the G614. http://www.ultraseal.com/pages/tbzipperruptures.html 2. A number of ST manufacturers do build the ST235/85R16F tire rated at 3960#...

The SpecialTrailer (ST) presents a challenge to the first time RV trailer owner. Most often they are just not familiar with the numerous design and specification differences between those tires and the ones they are use to. They are too acclimated to their experiences with their every-day tires...

In my research I've come to the conclusion that the triple axel fifth wheel toy hauler presents its owners with severe weight distribution problems. At RV shows, Rallies or other events where you can have your trailer weighed as you check-in I've seen triple axel rigs check-in with a single...

Daggonit I always take a lot of heat for pointing out regulations. But sometimes it needs to be said just because of the safety factors. Having a great feeling about tire strength can just go so far, then you're going to run into snags. The absolute minimum standard for tire fitment to RV...

I see you have used Discount Tire to find replacement tires. Here is a reference from their on-line web pages. http://www.discounttire.com/dtcs/infoTrailerTireFacts.dos Becoming more familiar with the ST tire design and their operating parameters may help your Maxxis tires last a little...

Let me qualify where this post is coming from. I don’t know the certified GAWR for your unit so this information is just informative in nature. RV trailer tire/rim fitments - by regulations - are determined by the GAWR the trailer manufacturer set during the certification process. That GAWR...

What I see in your picture is a tire sized ST235/80R17. That’s very disturbing because the TowMax STR isn’t manufactured in the 17” diameter. Just coping TowMax pictures when I noticed the 17. TireHobby

The new power King TowMax STR series of ST tires have an added nylon cap on all 15” & 16” sizes. The nylon cap is designed to help prevent early tread separations. The STR is a much improved tire and has a separate 4 year warranty starting with the 2012 production cycle. Of course those with...

In the reference provided below scroll down to paragraph S10. Those rules were part of the overall rules change that became law in early 2007. There have been numerous recalls for bad cargo information depicted on trailers cargo information placards. If there is a great disparity between actual...

Sorry, I forgot that going up in a load range is also considered “plus sizing”. Plus sizing requires the installer to set new recommended tire pressures for the plus sized tires. When using the same sized tire as you have, increasing the tire pressure is not necessary because the replacement...

An owner sets the stage for catastrophe when using replacement tires rated at 65 psi on rims rated at 50 psi. The only way to take advantage of the increased load capacity of the LRD tire is increasing the air pressure. Mr. Sawn Brennan is the east coast Maxxis tire representative...

The Power King Towmax ST235/80R16E has a diameter of 30.08". The Goodyear G614 RST LT235/85R16G has a diameter of 30.07". TH

You're not the first one to misunderstand the Michelin RV tire info. Michelin does not sell or market RV Trailer tires. Look in their Truck tire data book or maintenance manual. There are iconic depictions of all vehicles their tires are fitted to. There are zero references to RV Trailers. Read...

It would behoove you to carefully read the reference before using a Michelin LT tire to replace a ST tire. http://www.michelinman.com/mediabin/Approved/Michelin/Visuals/Digital/Owners%20Manual_Post_Promise_Plan.pdf TireHobby

You got me. I’ll rephrase my statement. The official axel ratings are found on the vehicle’s certification label. That label will be displayed somewhere on the LH side of the forward exterior section of the trailer. Tire size and load capacity fitment are driven by the vehicle’s certified...

According to the specs for Big Country models, Heartland is using the ST235/80R16E for both 6000# and 7000# axles. Perfectly legal and within the minimum requirement for the 7000# axles. However, a caveat is required. Heartland MUST inform NHTSA by letter when using the 3520# ST tire on the...

The only 16” LRF tires are all going to be “off shore” ST tires. However there are lots of very satisfactory LRF 17.5” tires. Here is an example. http://www.yokohamatire.com/tires/detail/ry103 FastEagle

RV trailer tire history is so important that you should never drive out of the dealers lot with anything less than new tires, put on at PDI. Then, check the tire pressures before leaving. Then, and only then, will the tire history be your responsibility. You know, at 30 psi, your tires were...

Here is a paragraph from a recent post on my tire blog. It explains how important I believe RV trailer tire history is to the owner. RV trailer tire history is so important that you should never drive out of the dealers lot with anything less than new tires, put on at PDI. Force the issue...

A tire “blow out” will almost always cause a big boom which may cause severe structural damage to the trailer. It’s important to troubleshoot the cause of such a failure to help avoid others like it. Most often it will turn out the condition was unavoidable. When examining the failed tire...

What caused the tire to fail? Did the guy that changed it have and ideas? Were all tire pressures checked before the travel day started? Were the exposed tire threads mealted? TireHobby

If your trailer and others like it also come equipped with the G614 tires and the high pressure rims to go with them I really do think you should press your dealer/vehicle manufacturer for a complete set of G614 tires . You are in the drivers seat here. The regulations clearly state that “at...
