Ok, what psi do you all run your trailer tires at? I was @ 32, but got cupping on the tread from too much bounce. Obviously need to boost pressure, but how much is safe? Talking regular trailer tires, not auto, nothing fancy. 19' openbow runabout.
Thanks!

It depends. Marathon load range B are rated at 35 psi, while load range C are rated at 50 psi.

I asked this question a few weeks ago and everyone said bump them up to 50 psi. I wasnt comortable with that much but I did take them from 32 to 45. I only took a small trip a local lake but it seemed to handle better with less bounce. I have carlisle trailer tires that are rated at 50 psi.

I keep mine at 50 and have not had any problems.

I try to keep mine around 50 as well.

I like to run the Carlisles at 45psi as well. wink That allows 5psi room for expansion when the tires heat up in that blistering 120 degree Arizona Summer. :D
Just verify the maximum inflation pressure stamped on the tire and stay within it. :)
Tandem Axle trailers are notorious for chewing up tires. :mad: Cupping on the back axle tires is common due to turning and dragging the tires around.

Is anyone running radials?

Always run the maximum pressure recommended by the mfg on trailer tires. Just make sure you check them before every tow and COLD.
Running less pressures results in increased friction/higher tire temps and increases the chances you will have a blowout.

Is anyone running radials? A lot of the trailer tires these days are radial, I've had the best luck with mine. I run at 45PSI. Had three sets of BiasPly tires and would go through them very quickly, maybe 6-8 thousand miles, radials been twice that already showing hardly any wear.
BTW- Tire expansion from heat will increase PSI by 8lbs.

Extream insists to keep them at 50 psi.
AND:
Replace them every 4 to five years if they are worn or not.

I run 50 psi on my trailer tire goodyears. One time on my old truck, I was suppose to run 35psi, but didn't check them, and the tire blew off the rim and I was running my Boyd rim alluminum to pavement. jawdrop

I have been runing radials for years.
Then my local GOODYEAR store told me that it causes trailer sway. argue
I thinkhe is MESSED UP :mad:
I am staying with my radials
