GY told me they don't make a tire that will work. They could not say why their inflation chart shows 95 and 110lbs of air pressure. I believe my trailer has a GVWR of 15K with over 2500 lbs of that being cargo capacity. I am going to order the Sailuns an have them mounted by Discount Tire. I will have to install them because there is no way I can maneuver my rig thru their parking lot. I think I will do 2 at a time and actually only have one tire jacked up at a time. I will use the spare to keep 3 wheels on the ground at a time....not sure if I NEED to do that but I feel more comfortable having only one at a time jacked up.


15k with 20% pin removed leaves 3k per tire. Either of the GY tires I mentioned will be just fine and you won't have to support Communist China.

GY told you that because your RV came with "F" tires.

Thank you all for the advice. Maybe I will take all 4 at once, what ever tire I get. Maybe I will go weigh my trailer again and see the axle weights since it is loaded as if we were hitting the road...minus some food. You have all given me lots to think about.

Know your weights then decide.

It’s good to know your weight , but no way in the world would I run a Goodyear E or G rated tire on a 41’ fifth wheel @ 15,000 GVWR even if it is only 3000 per tire . I’d want my tires G rated and at least 4080 on weight rating . Those Goodyear’s just don’t get it done on weight ratings . There is no question on the Sailun S637’s in either the 235/80/16 or 235/85/16 . I run the 235/85/16 on my 15500 GVWR fifth wheel.

Quality US made Goodyear G614's the issues just keep on coming, as well as the Endurance , blowouts ,plus wear issues . Great tire for the weekend warrior or light trailers ,not a good application for the heavier fifth wheels, just don't meet the weight ratings nor do they last.


How much more simple can we say it, the Goodyear tires do not have a capable rating for the bigger fifth wheels, Big reason you are seeing Westlakes , Sailuns etc. on bigger fifth wheels, that's a fact.

Montana used to offer the G614's , no longer.

I installed Endurance on my 5th wheel back in early January and immediately took a 2500 mile round trip to Arizona and back traveling at 70-75 mph with no issues.

Whole different ball game , then applying the Endurance 16" E rated tires to a heavy 41' fifth wheel. Comparing apples ,and oranges here.

I totally agree with Cummins2014.....how heavy your trailer weighs makes all the difference in tire choice.

I love my Westlake G rated tires....when time to replace it will either be them again, or Sailun 637s.

I had new Westlakes on the new to us fifth wheel we bought a few months ago , was skeptical about them not hearing much about them . I decided to sell them and get the Sailuns . They were identical to the Sailuns , couldn’t tell them apart other then the name on them . They too were an All Steel radial .

There is several of these All Steel radials showing up from overseas, I have the feeling they are going to prove out being the same quality as the Sailuns. Westllake being one getting into the G rated game . Unfortunately there is not a G rated tire made in the US with the 4000 lb rating or higher that I’m aware of . Big reason you are seeing these overseas tires showing up as OE on the new fifth wheels . I know the 2020 Bighorns come with the G rated Westlakes .

Westlakes were being used on Redwoods and did do well, now they're using "Goodride" and so far don't sound any better, folks just see "Good" and thing they have Goodyear's till they fail.
