Tire Pressure

[dscott72]

I have a 2011 Rockwood Freedom. I purchased the camper used so I don't have the owner's manual. Does anyone know what the correct tire pressure needs to be on the trailer/camper?

Look on the tires themselves.

TT tire placard location.
If you bought from dealer Shame on them for not providing the most basic safety info.

Anyway, you should have a sticker or plate attached to front end of the driver side of the TT with GAWR, GVWR, and tire size & Inflation info. As a tire engineer I can tell you that you should run the Max pressure molded on the tire sidewall. This will lower the Interply Shear forces that are trying to tear your tires apart every time you turn a corner or go around a curve.

Should be able to find owners manual from Forest River online.

Why does it appear so few TT owners know where their Certification Label (Tire Placard) is located?
This has tire size, Inflation and axle rating information on it by law.

And P.S. the manual likely won't have anything to say on the subject. RV manufacturers usually don't produce manuals for each model - usually just their entire product line, where things are described in vague, general terms. There are therefore too many tire possibilities to cover so they will just refer you to the aforementioned label...

which looks like one or both of these on the forward end of the driver's side.

Of course, the label is only correct if the same spec tires are now in use (you say you bought the trailer used so you really should check that against the label). In my case, I've upgraded from load range C to load range D so I now use a cold pressure of 62psi (max 65 on sidewall).

Seeing that its a 2011, many will say you should start thinking about replacing the tires so you may want to consider going up a load range if the loaded trailer's net weight is closer than 85% to the sum of the tire load maximums.

Spec label MUST be 100% correct for GAWR, Tire Size and Inflation when unit goes off the assy line. If the dealer makes any changes PRIOR to sale the dealer is responsible for applying a new cert label.

Wrong info n label is an easy way for MFG to end up with a recall on their hands.


50 psi on St225/75R15 LR-C means the MFG only rated the tires at 2,150# per tire and keeping the axle to 4,300 or less meets that requirement. Some play games with tongue weight to allow the MFJ to give a higher GVW than 4 tires can support.

I agree that the label, legally, should match the tires as delivered and that the tires and axles are chosen to (barely) carry the load on the tires.

But the OP said this was a 5-year old, used trailer so whether they still match is not guaranteed (and the Rockwood Freedom series only has two weight-bearing tires).
