Too Heavy for E's Tires..either LRF/LRG or 17.5 tires

I put goodyear g614 tires on my trailer. 7k axles as well. I needed new rims for the higher pressure. I have about (3 axles) 24k of tires on 21k of axles on a 18.5k trailer. The g614's are also rated to 75 mph, so no issues running the desert at speed in states with higher then a 65 limit.

Has anyone located the Goodyear position on the speed rating for the g614 235/85r16? I am having a hard time finding it, but I thought it was a 65mph tire. It is what I am running now, but just experienced a blowout (claim open with Goodyear).

I tried the link below, but could not locate the content. I'm pretty good at the google search but must be missing something.

Thanks for the clarification.

just a quick thought..When I weighted the 5er last year on my trip the camper axle weight was 12,540lbs...now even at a equal balance between the axles that mean each axle comes in at 6,270lbs...that 500lbs away from my tire max..now my 5th wheel is sitting up slightly higher in the front,which in turns puts or shifts more weight on the rear axle/tires. Well now my rear tires are at there max...getting ready for another tire failure...thats way to close of building a camper to its max capacity from a manufacture...so its either spend 650$ for Hercules Comercial H-901 LRG 3756lbs and Puncture-resistant tire... or thier "Power STR" trailer tire with a 36month warranty and has a LRF og 3960lbs @95psi..(smoother ride vs. 110psi.)...then from Rickson Wheels the 17.5 wheel package for 2400$ with Forged rims and Sumitomo tires..Now 2 type of tires change the capacity..1st is 4800lbs or the 2nd of 6,000lbs(too much for my needs)...if I speed the 1500$ for goodyears G G614 tires which is only 3700lbs I rather go for 4800lbs 17.5 tires

What's a "axle tag"? If you meant tag axle the Montanna 5th wheel does not have a tag axle, it does have dual axles.

I replaced my 7 year old G614's last fall because of age, tires were in good shape, I had 4 years and 20,000+ miles on them don't know total mileage as they were on the trailer when purchased. Replaced with the same , 12,500 on trailer 7,000 axles run em at 110. I know kitchen/entertainment side carries more wt which would merit rated pressure.

I re read the post. Yes that would be too low of air pressure. I thought he said total RV weight. I stick by my statement of using the inflation charts. Call GY they will tell you the same if you are going to a higher load rating. They said to use the chart and add 5 psi based on the heaviest tire. Also they said if you over inflate the tire, wear and tire contact to the pavement will suffer. I would not worry about using 80psi aluminum wheels with using higher pressures.

The new Winnebago flagship in the July trailer life has E tires. I guess the rv companies know the rv folks are un informed. I wanted to say stupid but choose not to.

Agree with running 110 psi in the GY G614's..It's recommended by my 5er manufacturer as well as Goodyear...My 5er has a GWR of 16950# with 7,000# rated axles...the 5er came with GY G614's as OEM....Have had one tire failure from tires that had an 0606 manufactured date, but my tire failure was caused by a weak spring pack...I've towed all through the mountains of WV, TN, NC,SC and VA, run my tires at 110 psi and zero issues...

Get the GY G tires they have been VERY trouble free since 07. Don't worry about your rims run the G's at 85psi that is the lowest pressure on their inflation chart. Weigh your axles look at the chart and you will see you have a safety margin at that pressure. I did the same on our Avion Platinum E to GY G's 5 years never a problem. Several trips from Palm Springs to Phoenix at 75+ mph across I-10.

Contact GY they will help you out changing to the G's.

Yea...85 psi in G614 at your weight is not good advice....that puts you down to 3170 lbs of capacity per tire. You are trying to upgrade, not downgrade your capacity.

IF you have 110 psi rims, then the G614 is a good choice for your existing weight. Run them at 110 psi...despite these charts, Goodyear recommends running trailer tires at the max capacity psi listed on the sidewall...110 psi. IF you don't have 110 psi rims, you may want to consider the 17'5 option as your cost will be about the same or less. And if you go with new rims, make sure your research the approved offset for your specific axles.


The below is the goodyear position on trailer tires....

Special Considerations
Unless trying to resolve poor ride quality problems with an RV trailer, it is recommended that trailer tires be inflated to the pressure indicated on the sidewall of the tire. Trailer tires experience significant lateral (side-to-side) loads due to vehicle sway from uneven roads or passing vehicles. Using the inflation pressure engraved on the sidewall will provide optimum load carrying capacity and minimize heat build-up.

in central Oregon I would guess that 40 % of the guys with 245/75r16 tires have upgraded to 265/75r16 tires .
most of those are on the stock 6.5" wheels .
my friends and I have done that for a decade with no issues .

I have seen that also on many Chevy's. Tire really rolls in at the bead. Most trailer wheels are only 6". And a wide tread is not the best trailer tire.

I quit commenting on Goodyear tires about 10 years ago as no one seemed to listen. I had nothing but grief out of Goodyears, 8 or so blowouts, $25,000 rig damage, etc. I went to Michelin E Ribs, which were theoretically over weighted by a hundred pounds or so, but never had another blowout/rig damage.

No.... you didn't (quit commenting), LOL!

The RV forums are full of GY Marathon -mfg in US & China- horror (failure) stories - and not just on 5th wheels.

"Fool me once" folks get "more of the same" free replacement tires from GY, and (usually) trailer damage repairs paid for by GY.
(Of course, nothing for their down time)

They happily come back for "fool me twice".

BTW - better "G" tire options than G614....but why comment?..:B
