PSI for camper tires

[Guy]

I have always used 65 PSI for my 17A camper tires, as that is the max set by the tire company and what has been recommended by others. Recently I saw a video by Reece saying to only inflate tires to 50 PSI. What do you folks set your PSI at?
Thanks.

I go by whatever it says on the trailer so mine are 50 psi.

The tires supplied by Escape on our 21 were 50 PSI max so that's what I ran with. Replaced them with Goodyear Endurance which have 65 PSI max. I usually run them at 60 PSI.

Not knowing for sure I looked on the Goodyear site...


"Goodyear recommends that tires be inflated to the vehicle manufacturer's recommendations as found on the Vehicle Tire Information Door Placard or the Vehicle's owner's manual. The placard can be located on the door edge, doorpost, glove box, or fuel door. The recommended PSI should not be confused with the maximum cold inflation pressure that the tire is rated to hold, which is found on the sidewall."

The sticker on my Scamp says 30psi... can you image? As tires improve, I wonder if we should still use the trailer manufactures recommendation....

Who would be the decisive authority?

When we picked up our 21 last year we were told 50 PSI.

I had / have D rated tires on both my Casita and on my Escape ( Rated for 65 PSI Max)
I inflated the tires on both trailers to 60 to 62 PSI .

I also added the Endurance with max of 65psi. I inflate to 58 so that when hot they don’t go over 65.

I run my E-21 tires at 50 PSI.

This is what I do also. In summer running I start the day at 60. They will make 65 in the late afternoon when I stop, and lose 5 lbs when they cool down. In spring and fall I run them at 62psi they may or may not gain depnding upon road
Temperature and probably speed but my tow speed is pretty steady at 62mph. On four lanes -about 57 on two lanes day in and day out with mixed roads, short rest area stops and gasoline my average distance covered per hour is 50 miles. Meal time not counted.

65 psi is the cold inflation number, so you don't need to try to compensate for conditions. Just check inflation before travelling.

My D-range tires max is 65 psi and I also run at 60-62 psi.

Maybe I’m misunderstanding what you are saying. Four Goodyear Endurance 205/75R15 tires inflated to 50 PSI have a total capacity of 7280#. More than enough for a 21 with 5000# GVWR.

[dfandrews]

We have a 2015 Escape 17A. With all our gear we are at about 2600 lbs. There's 350 lbs. on the tongue, so 2600-350 = 2250 lbs. on the axle.
I don't assume equal weight side to side, so figure 1300 lbs. per tire.
I run 45 to 50 psi.

Carlisle says max. is 50 psi, and is good to 1820 lbs.
For every 5 lb. reduction, you subtract about 100 lbs. capacity, so I could run less, but I don't. With the Dexter Torflex axle, each wheel acts (somewhat)independent of the other, and so we get a very smooth ride of the trailer even at the higher pressures.

That's the logic I used with my new Endurance tires on my older 21 with 4500# GVWR.

I tried the cold max of 65 psi for a short trip and found the ride to be very harsh. Going back to 50 solved that problem. And given the load capacity at 50 I have no worries that should I blow one tire the other will safely carry the load.

Run the new Goodyear Endurance on our 19 @ 55psi. Tried 60, but too harsh 55 rides nicely.

[Guy]

Thanks to all for the input. I settled on 53 PSI.

[Vermilye]

For what it is worth, I keep the Goodyear Endurance tires on my 21 (weighing in at 4900 pounds) at 50 PSI & after 8000 miles, tire wear looks normal.
