camper tire pressures

I have a Keystone Laredo (29 BHS, w/slide)

tires say 65 max PSI...do I put the max in or a few less? When I bought it, I noticed it had 50 psi in them. I currently have 58 psi in them.

We are getting ready to head to Yellowstone next week and I want to be sure I have the right PSI in them.

Thanks!

the side of the trailer should have a sticker that has the tire pressure listed. Folow it. In most cases it will be the max pressure for the tire load rating that came with the trailer.

if not most ST (trailer) tire mfg recomend running at the max inflation pressure regardless of load. That is the way they are designed.

Others go by tire load vs. pressure charts. I don't, I just run them at max pressure, they still wear fine and even and last 25-30K miles.

Use 65 PSI. You don't say whether this is a new or used trailer. If it's used, check the date code on the tires and seriously consider replacing them if they are 5 years old or older.

Thanks guys! I just went back and put them all at 65 PSI.

GLad you asked this question. We have the same trailer 2011 and my husband was questioning this also!!!

Agreed. I run mine at max rated sidewall pressure regardless of load (although I am close to rated load) -- maybe a couple pounds over (52-53 psi) and have no issues with my Chinese GY Marathon ST tires.

I run max pressure. My tires have 110 PSI on them and that is what they get. Check your pressures when tire is cold. I do it in the morning.

Absolutely right, follow the max cold pressure on the sidewall of the tire.

Don't trust a sticker on the side of the trailer, it doesn't have any idea what tires you have or what operating pressure they were designed to use.

If you are running >50 psi, make sure your valve stems are either metal or have a metal tube (inside the rubber stem). If they are all rubber, they are likely standard stems, only good for 50-60 psi. VERY COMMON error, even by tire shops ;) They can bleed down over time, leading to possible catastrophic tire failure.

We get a tire pressure question virtually every week and it's the same question only with a different tire pressure.
You could search this Forum for previous posts OR load it up to the cold pressure rating and drive on; which is what I do.

Thanks for all of your comments. We just got back from our trip to Yellowstone (2,500 miles!!). I can't believe the difference in towing from the two week-end trips we had before (with the tires at 50 psi and our cross-country trip to Yellowstone (with the tires at 65 psi). WOW! I never would have thought that would have made such a difference! Not as much sway, much more control. I was amazed.

I know, you probably think I'm a little dense. But I really did not expect that!
