Goodyear Endurance tires
Greetings
First post.
Looking to replace tires on my 2014 Avalanche 355rk. I have four successful years with Trail King tires. I do run a tire monitoring system. I would like to install GY G614 but price is extreme. Anyone have experience with the GY Endurance. I guess it replaced the Marathon.

You are comparing apples to oranges when you compare the Goodyear G614 to the Endurance line. The G614 is a Load Range G tire (not available in LRE or LRF) while the Endurance line is only available in Load Range D and E.
There is no "direct replacement size/load range" correlation between the two tire lines.

If your wheels are rated for LRG tires, put Sailun S637 tires on it. These are all steel ply tires that come in two sizes. ST235/85R16G and ST235/80R16G(to match the diameter of china bomb maypops LRE tires).

Not an issue with that one. Has a better tract record than the GY G614.

I have the GY Endurance load E. About 2000 miles so far. I like that I could put 80lbs and the higher speed rating. Its a nice cushion compared to 65lbs/65mph rating.

The Sailun S637 tire is as good as the GY G614 at way less cost. I’d buy them over GY any day if the week and take the wife out to dinner several times on the money saved. Made in a foreign country is not the issue. Except for Traier King tires. They are junk

The GY Endurance line-up includes a new - to the market - tire size. It's the ST255/85R16 LRG with a maximum load capacity of 4080# @ 80 PSI. However, IMO, it's not going to fit well in many of the existing Keystone wheelwells. The OD (33.1") may also hinder many applications. Also note that it's minimum rim width is 6.5".

It would help if you could provide:
Current complete tire size including the LR
Actual scale weight reading for the load on each tire
Vehicle Certification Label (aka Tire Placard) tire size & Inflation and GAWR

Abbot, you let Trailer King tires satisfy you for four years, why would you want to change? They can be had on most Craig's List for little or nothing taken right off new RV's. You did some research and learned that Sailun weren't for you because they are built in China. Dozens and dozens of experienced RV'ers on this site and many others go to bat every day for Sailun but you wipe that off the list because of China. I believe you need to return to Google and extend your research a little further.

I have 2+ years on Hartland 235R85/16 tires that are load range G, made in China. Rated for 81 mph. I have been very happy with them. Cost less than $200.00 each. My TPMS has kept me out of trouble from 2 flat tires on the TV, but on flats on the 5er tires. Seldom have to add air to them.

His specs are;
GVWR: 15,000#
GAWRs (2): 6,200#
Tires: ST232/80R16E
There is no strong reason for him to increase tire size. The current size and load capacity at 80 PSI are providing about 12% of load capacity reserves above GAWRs.
However, using a replacement size ST235/80R16 LRG inflated to 90 PSI would increase his load capacity reserves without changing the designated tire size on the trailer's placarding. (The PSI limit on the current wheels would have to be verified for the higher PSI capacity LRG tire).

Load range "E"
Pay attention to the specs on these new Goodyear tires.
In a 235/80R16 (which I assume is what OP needs), Goodyear is the only tire on the market that has REDUCED the max load to 3420lbs instead of the industry standard 3500lbs. That's 160lbs per axle reduced carrying capacity.
It may not mean much to some, but in my toy hauler I needed 3500lbs per wheel (7000lbs axles) and only caught this detail at the last minute. I mean, shopping for Load range E, you'd think they'd all be the same.
Even my tire shop was surprised at this change.

What is the official GAWR values on your trailer's certification label.
There are three official load capacities for LRE ST235/80R16 tires. 3420#, 3500# & 3520#, all at 80 PSI. There is a FMVSS standard that covers that situation and reads sort of like this; Without documentation, they all default to the lowest value, 3420#. When the trailer's axles are certified at 7000# the vehicle manufacturer must show NHTSA documentation that OEM tires sized ST235/80R16E having at least 3500# of load capacity were installed as OEM. The 3420# tire does not qualify. When Keystone - or any other trailer manufacturer - uses the ST235/80R16E tires as OEM on 7000# axles without documentation, they MUST officially derate the 7000#axles to 6840# or less and certify the value used on the vehicle certification label.

GY Endurance
I had to china bomb load range D on my trailer. I’m pulling a sprint 296 RLS fifth wheel. I put the GY endurance load range E on it. I haven’t had it on the road yet but I’m going to Kansas next week. I will have over 2000 Miles on them when I return. I run a TPMS so here’s hoping I’ll not have any problems.

Tires take a minimum of 5 years to earn a good or bad reputation. Endurance is looking OK as reported by those paying to test them. A 5er with a GVWR over around 13,000# and especially around 15,000# should have a LR G tire IMO. The LRG tire with the best rep is the Sailun S637. Made in China at 1/2 the price of 2nd best GY G614.

Our Avalanche is a 13 and I too had good luck with the Trail King tires. However, when it was time to change them out I went with the Sailuns. Two years later I couldn't be happier. Unless they really decline in quality I probably will not run a different tire.

I am looking for the published Tire & Rim Yearbook that shows multiple load capacities (single application) for a single size tire and single Load Range for ST type tires. In my 40 years as a tire engineer I have never seen this so am looking to learn something new.
