Air Pressure for A128S

[shiggins]

What tire pressure do you use? Tire max rating is 55psi.
Thanks

Use the max pressure printed on the tire side wall. That is the pressure which gives them the rated weight capacity.

In my case with the "D" rated radials, it's 65 PSI.

If you have 55 PSI tires, they may be load range "C." "D" tires are required to cover the full GVWR of a camper. I'd check the sidewalls again for a weight rating and compare it to the real weight of the camper to make sure the tires are not overweight.

The only time I've had a blow out was when a shop put "C" rated tires on a camper. It is amazing how ignorant a tire shop can be about camper tires.

Are you sure it says 55? I have not seen a 55 before. Mine are also 65 psi. As stated go with the max pressure as stated on the tire.

On the drivers side of your trailer you will see tire psi as the manufacturers specs that's the pressure you should use

[shiggins]

yes its 65 max pressure which is also called for on the drivers side.
If I'm not carrying a max load should I still keep the tires at 65psi?

That is the basic safety rule.

Do you know the capacity of the tires when not at max load? Some manufacturers publish this info and some do not. I've never seen it for the Karrier tires on an A Frame. If you don't know, then run at max pressure.
