View Full Version : My take on the 614 debate

Seems to be a lot of debate on the price of the 614's and any cheaper alternatives that are out there. Speaking for myself and myself only, I think I will stick with the 614's since I have had zero problems with them on the last two rigs covering 4-5 years of use (two sets - because of trade). I was even more impressed after we began the last trip to Hilton Head. On my pre-trip inspection, I was dismayed to see a couple glimpses of shiny metal about a half inch from the edge of one of the tires. Knowing that I had picked up a couple of nails, I went to get pliers and screwdriver to remove the nails and fully expecting to hear the sound of escaping air when I got them removed. During the removal process, I discovered that the nails were about a half inch long and went in at an angle. I pulled them out and never heard a sound. Soaked the remnants of the holes with soapy water and not one bubble. Being impressed was an understatement even knowing that the nails were on the edge where the tread was the thickest. To be safe I estimated the penetration depth and checked the tread depth and further convinced myself that I had either been totally blessed or these were pretty sturdy tires and then settled on the knowledge that both were true. I am confident that the tires suffered no ill effects after the 1100 mile round trip to NC and bath with no problems. Going forward, I do not think I will experiment since I am confident that I have found a reliable tire. Other opinions may differ, but I just wanted to give a report as to my experience. I am totally satisfied with the 614's!

Some times the most expensive turns out to be the cheapest. Buy a cheap tire that tires the side off of your camper and you got an expensive tire.

I think you look at it in the right perspective. It all comes down to owner confidence, satisfaction, and peace of mind when you select the tire brand and load range for the rv that you own. Sure, crap can happen no matter what tire you have...but less likely for most issues if you are running a higher load range with reserve capacity than the "delivery" tires put on by the factory. Long may you tow in safety. John

Bingo you do have a point. Back in 2012 I had a IS failure on one wheel on my heavy side while in Elkhart. Thought something was wrong but couldn't figure it out till we stopped to camp near Indianapolis. That 614 carried all the weight from the heavy side of the trailer all that way over all those bad roads and RR tracks and three years later is still on the same wheel. Your right, I won't be looking for another brand when these are done.

I too have been very happy with my G614s. People like to vote with their wallet but I still like buying things made in the USA (I know, my diesel engine was assembled in Mexico. But I have the satisfaction of knowing the company is still a US company and not Communist Chinese.) When I did a recent cost comparison, the G614s worked out to ~$.04/mile for a set of four (based on ~$300/tire and 30,000 miles per tire, which is less than what I have on my G614s). The Sailuns priced out at about half that but unknown on tire wear. For the ~$.02/mile difference, I too will stick with my G614s knowing the money is staying here in the USA.

I'm with Bingo. No more troubles after installing G614s on our first Monte. We have had this one for a little over a year and have them set at 110 and they have stayed there except for temperature changes making them move.

After running 614's now for quite a few years with zero problems we will usually default to what has worked so well for us in the past our good old 614's.

I just replaced my G614s had 40,000 miles on them over 5 years. Cost me $%1,800 mounted and balanced with a life time warranty. If it can't be repaired I get a new one free. I got them from America's Tire and I am satisfied. You get what you pay for.

I have considered the G614s and have spoken with others that like them but keep them at 80 psi. Does that defeat the purpose of paying the extra bucks for the best? My lousy Marathons probably are adequate at 80 lbs but fail at every other measure of durability.

Goodyear bought my Marathons back after one year of use with about 5-6000 miles on them. I complained to them that they were underrated for my rig and felt a disaster would be immanent had I continued to use them. Traded them in on G614's. The G614's are a substantial tire compared to the Marathons and much heavier. I keep them inflated at the recommended 110 psi at cold temp. I have a TPMS and it shows little variation when traveling. I have had much greater confidence in pulling the Monty now. We plan on trading our Monty in about a year from now and if the newer Monty or SOB has an ST or a different LT tire, I'll switch them out. Dealers will admit that they're the "gold standard" and the best tire out there, period. There may be other LT tires that could handle the speeds and weight, but it's not worth it for me to experiment.

I am on my second Montana and my 3rd set of G614's. It all comes down to can you sleep good at night. If you can with stock OEM bombs wonderful. I prefer the extra security of the Goodyear tire, it was created for heavy trailering, and when you pull a Montana that's heavy towing.

We had tire problems before we got the G614's. Did I pay more? Yes! Am I sorry? Not one bit. Did 13,000 mile Alaskan trip, including a broken spring, but no tire problems.

When I got my Monty, this forum advised the G614 upgrade. I did and have had only one minor issue; a slow leak. Turned out to be a loose valve stem core. Tighten it and now it's been over a year since I even had to add air. TPMS shows everything is fine. 9000 miles so far.

Hi Bingo

I put 40,000 miles on my first set and now have about the same on the second set. The only reason I got the second set was because they came on a set on 110 PSI rims I purchased from the form and they were only a year old so I kept them instead of using the older tire.

And FYI the first set including the wheels are on an equipment trailer my partner and I haul antique engines on.

Rating is stamped on the back of the rims, but you should be good with the recent model year.

I had a set of Toyo LT tires come apart on me. Lost two tires in 4 days on a trip to the west coast and not a hot day. Tires had 20,000 on them and had recently completed a trip to the East coast. Tires still looked good, but when looking at one of the remaining good ones, there were cracks between the treads. Les Schwab, took all four back and gave me 71% of what I paid for them towards any tire I wanted, didn't have 614's in stock so those weren't a choice. The manager had good things to say about the GEOSTAR's so went with them, 7000 miles on them so far, keeping finger crossed.

I should of said that when I upgraded to G614 I did it before I picked up my Monty. The dealer swapped the rims and tires as a set. They worked with Tredit to trade out my original rims and tires with the G614 option rims and tires. Since Tredit supplies Keystone with those tires already mounted on the rims, I got the official G614 package.

If you have the Marathons, as I suspect, things can get worse in a hurry. I didn't like having to replace my new tires on my Montana either. But, it is peace of mind now that is very valuable. The expense is a distant memory.
At the very least, invest in a tire monitoring system. At least that way you'll know when the fur flies.

This tire issue is making my blood pressure go up. Keystone says the tires meet the specs designed by the engineers... Goodyear says the ST235/80R16 is sufficient for the Montana .... Plus they don't make G614s that fit the "80"s.... Not sure where to go from here....

Any suggestions please?

Thank you!!

rohrmann
08-06-2015, 11:21 AM
Many of the Montana models, if not all, were available with the optional G614's, which only come as an 85 series tire. There is a very minimal difference in physical size, so there should be no problem with fit. Your wheels should be rated 3750 lbs and 110 psi, which is perfect for these tires. If cost is an issue, the Sailuns seem to be a good substitute, but the reason we went with the G614's was availability.

mlh
08-06-2015, 11:47 AM
This club is full of people who had ST tires and thought if they did every thing wright and did a little tire dance to the tire gods they wouldn't have a blow out, only to take the side of their camper off with a blow out. Skip the tire dance and get rid of the ST tires.

614's will fit your rims just fine and should give you a good 6-7 years of trouble free life. What you have say their ok on the sidewall, but have not proven to be so for many owners.

Anna and Jim ... you can read pages and pages of Marabomb tire failure stories. They simply don't hold up on trailers of our size no matter what Keystone or Goodyear say. Farm trailers and 6K RV's seem to get along with the Marabombs. Get something else like G614's or Sailuns for peace of mind. With the Marabombs it's not if it will happen to you ... it's when will it happen to you. There's really no decision making here ...

I only got 2 1/2 yrs on my Marabombs (about 12,000 mi). I have one of the lighest trailer Keystone makes. Replaced them this summer, as we were traveling, and noticed one was starting to seperate. Replaced them with Michelin LTX/2.

I guess it will have to be something besides G614s since they don't make them to replace the 80s we currently have.... Weight wise we are good - we've done the calculations several times and verified with several official sites. My concern is that the RV sat on the dealer lot almost a year before we bought it.... The sun is a killer on tires I'm told.

We appreciate all the guidance and are doing our research. Thanks to everyone!!

A Goodyear G614 235/85/16 can replace your 235/80/16 there is no size difference to worry about. Only issue you might have is if your rims are not rated for 110 psi, and that easily checked by looking at the back of the rims to see what they are marked for 80 psi or 110 psi

I would be for sure getting those ST tires off your fifth wheel as soon as possible

The 80 aspect ratio is a ST tire thing. The Goodyear 614's are LT tires and LT tires come with an 85 aspect ratio. Montana offers both ST (Trail Kings or some such trash) and LT (Goodyear G614) tires when the rig is ordered. Either tire type use the same rims.

So Montana supplies G614s on their trailers, 100's of MOC members use G614s, and most everyone in this posting and the hundreds of other tire postings recommend G614s and yet you just don't get it. In that case, stay with the 80 aspect ST tires you have or buy any one of the other 80 aspect ration ST tires available from the various Chinese (and some USA) manufacturers. This are the *ONLY* ones which meet the perceived need to have an 80 aspect ration tire.

I saw a couple at our Camper World today. Guess what they had just come off I 81 with a blow out. The man said he never did like the Trail King tires they were made in China. I told him as far as I knew all ST tires were made in China. I told them with their heavy Aspen they would continue to have problems until they got rid of the tires on their camper and got G614 tires. Did they listen? Probably not but they will remember what I told them.

Finally making the change again. While we were in Prescott we has tire issues and were told to go to Vanguard 235/85 r16. Two short trips later, the tires are falling apart. Now recommendation it is to for Goodyear 235/85 R16. They giving u some credit back, but was not expecting another tire change. Lost count in changes. Anyone thoughts on these before I bite the bullet here? Fortunately the tire failures were caught at the tire shop for a nail in tire. Is this the right choice?? 2007 3500RL 4-slides

There are many tires of that size. What is important is the load rating, not just the load range. If you put an LT tire on in that size, it could be load range 'E', and that most likely will have a load capacity of 3042 lbs. The tires that have been talked about are Goodyear G614, which are load range 'G', and have a load capacity of 3750 lbs. The 'E' tires are called a 10 ply rated tire, where the 'G' tires are called a 14 ply rated tire, and in the case of the G614, the tire is 100% steel cords, much more durable than the 10 ply LT or ST tires.

While getting new truck tires installed the Costco employee looked at a little bigger tire 285/16 and just by going to a wider tire I could pick up three or four hundred pounds more capacity still in a load range E. My stock rims were to narrow to support the wider tire so that was a no go but they are still rated at 3340 if I remember correctly. I think the G load range tires are a great tire, especially with the extra plys. I also think if people check their rim width they might be able to get more capacity with a bit wider tire if the rims will support it. Similar to needing rims that will support 105 lbs pressure for the G rated tires. If I looked correctly at $350 dollars plus or minus a tire these 614's are pretty pricey.

Spending the money on the G tires is like the old saying, 'pay now or pay later'. If you feel lucky, stay with the 10 ply ST tires. We went through 5 of those tires, and were very lucky that I caught all of them prior to total failure. After the 5th one, decided to bite the bullet and got a set of G614's. I can now cruise along without constantly looking in the mirrors for tire debris flying off the trailer.

Dam Worker
08-15-2015, 11:10 AM
I understand what you are saying Bob and I am sure that for piece of mind the 614's are great. If your trailer weight is not to high or your rims would need to be replaced to run the 105 lbs pressure than there could be other alternatives. Similar to buying 19.5 rims and tires for all the TV's that don't already have them. I would have to say that having 19.5" tires on your truck would be the safest route compared to the 16",18", and 20" tires. I was just trying to let people know that they can get higher load rating in the same series tire if they broaden their search. Some rigs weigh a lot more than others. My 3160 happens to have 7k axles but is shorter than a lot of other rigs so I have a lot more load capacity than some others and if I don't use that net weight than my axle weight is way less. There is no totally right or wrong (except maybe Maribomb) just different senerios of weights, travel distance and peoples budgets.

Have you verified your certified axle loads depicted on your trailer's certification label (GAWR)? It's found on the LH FWD external section of the trailer.

Unless there is a notation on it as to the specific tire load capacity, the certification label probably says it has GAWR axles certified at 6750# or 6850#. That's because some of the ST235/80R16E tires only provide 3420# of load capacity and that disqualifies them for service on 7000# GAWR axles.

Tires for RV trailers are fitted to each GAWR. They must support the GAWR not the GAW.

Dam Worker

Not only have I read the weight I have stopped at two different scales to see actual weight by certified scale. What I am trying to say is everyone is screaming about trailer axle weight but nobody is talking about TV weight. I guess I am not sure what the difference is? To me they are both important. My guess is that a lot of people are really worried about trailer weight and going to G rated tires but I do not see the same worry about their TV weight? More people need to stop at some scales and actually see what their setup weighs. Most highway scales are open even if their is nobody too actually verify what you way. I myself will not worry about G rated tires for awhile because I know that I am not even close to what my axle weight is. It is almost funny to read about trailer weight but when I look at the polls there are more SRW tow vehicles then dualies. This is like the 62 MPH that some people follow like a state law. In my humble opinion people should be able to tow their rigs at a speed that they are set up to tow verse a random number somebody chooses.
I am sure that some will bash me for being actually honest. Some people should probable never go over 45/50 because they can not handle any problems above that. Other people can probably go a bit more than that as they are able to handle different speeds compared to other drivers.

We have IS so we weigh each wheel seperately and on our rig anyway there is a significant difference between side of trailer and each wheel on that side are different also. For us, the 614's are a no brainer. As to driving speed, reaction times and ability to control the rig during a tire failure or other road emergency is greatly impacted by every MPH you increase. Even more so in the high speed ranges.

I understand your point. My HC weighs 9200 pounds and my truck weighs 8400. Take 1760 pound pin weight now my truck weighs 10160 and my camper weighs 7440. All dry weights. Even then I will not run ST tires. Those that ignore history are doomed to repeat it.

First, tires and brakes are the most important items on your rig. Even if you were to replace them every year it would be far less expensive then a funereal.
Second, the faster you drive the faster bad things happen. There are far to many drivers doing crazy things that you have no controll off.
Third, take care of what you can controle. Tires, brakes, speed and seat belts.
