2022 Eagle 5th Wheel Tire Upgrade Question

[Wildrice]

I have a 2022 Eagle 317RLOK 5th wheel with about 5k miles on Goodyear Endurance E rated tires. We have a long trip planned in 2023. Some of my travel companions are recommending I upgrade my E rated tires to a G rating. My question is I have stock Eagle 5th wheel 16 inch rims. Do I need to change the rims to jump to a higher PSI tire and load rating?

PS I have no reason to doubt the factory tires...they seem to be wearing as expected and I have a TST tire monitor system....just wondering if anyone else has done it and if the rims need to be changed in order to do this....Thank you in advance....

So here's my opinion.... And that is all it is
Weigh trailer loaded ready to travel
Then take the max weight on sidewall of tire you have
Multiply by 4
Thats the gross weight the tires can take
Now multiply by 90 percent
That gives you a 10 percent margin on the tires
Now compare to the trailer weight
If you are at 90 or above of the combined tire rating rate I would move up to the heavier rated tire but don't max inflate it. Use the tire pressure to weight table for the Heavier tire to get you the margin
Contact the manufacturer of your rim to confirm you can go over the 80 psi the load range E tires
Likely the rims are rated to 120 psi but validate

Your rim will have a psi stamp on the inside of the wheel. Myself I would not be worried about the E rated Goodyear Endurance tires

I really like Roadrunner II's math!!

It appears your GVWR is 12995 lbs. as posted by Jayco. Also posted by Jayco your tire size of ST235/85R16'E. Per Goodyear, those are 10ply sidewalled tires with a max load rating of 3,640 lbs @ 80PSI..

3640 lbs x 4 = 14560lbs. X 10% = 1456 (14560-1456 = 13104)

13104lbs vs 12995lbs?

Looks like your good per RoadRunner II's math..

But, my opinion is how does it tow? Does it wander? Does it feel like it wants to tip in turns? Does it feel stable?

The math worked on my 2021 Cruiser ST2916. But, it towed horrible. I upgraded to "G" rated Carlisle CSL 16 tires and wow!! What a handling improvement!! Felt rock solid going down the road.. until a gust of wind would come along... I"ll never buy a pull trailer that big again...

Anyhow, here's a "read" on the Carlisle tires below.

I will second roadrunners info, E is probably fine, but the best method is to weigh everything. I would not modify with a heavier tire if the unit is still under warranty do to the tires will be heavier and you will be running at a closer to maximum pressure for the rim. Looking that your weight GVW is around 13000 and the tires are 3640 a piece, and part of the weight is on the truck, you should have ample margin if you stay with the E tires. Also the G rated tires will be more jarring to the rest of the trailer when you hit bumps, which can cause other issues. but checking your weights is the best thing to let you know where you stand.

It's all about how much weight is on the axles. Fully loaded at 12,995 and using 20% for pin gives you 10,396 on the tires.
4 tires at 3640 lbs each = 14560 lbs
14560-10396=4164 in the positive,
4164 lbs divided by 4 = 1041 lbs in the positive for each tire. One side may carry more weight but you should still be good to go IMO.

I had Goodyear Endurance E's on my previous fifth wheel...many miles no issues.

As long as the weight margin is correct...I wouldn't change them early.
