tire air pressure for 3400RL?

I'm trying to determine my air pressure requirements for our 3400RL. They are measuring in the mid seventies? I can't find any literature, even on the tire, that is specific. Is it supposed to be 80? Also, I think I have read somewhere that some people deliberately keep them a little lower. Is there any good reason for that?

If the tires are load range E then the max pressure is 80psi and that is where I would keep them. You will have less sidewall flex and less heat buidup.

We have 16 inch rims and keep our tires at 80psi or darn close to it. Hope this helps.

We run ours at 80 psi. Also might add to the good info above that by running at max pressure, you will get better life out of the tire.

Wayne and Cathy,

You can get the RV Handbood by Estes at CW or other supplier. In there they have the Tire and Rim assoc. tables on tires. The handbood recommends loading the tires to actual weight on the tires. I try to do just that. The book explains why.

I recommend the following if you do not want to purchase the book:

For Trailer:
1. Always adjust the tire COLD, Not hot.
2. If you don't know the proper pressure then set tire pressures to 80 for LT and 65 for ST. (COLD)

For the Truck:
1. If your not using Tire and Rim pressures then follow the values on the door frame of the truck recommended for your rated GVWR.

The pressures recommended in the tables are for best tire wear.

Since our trailer weight does fluctuate (water or holding tanks full or empty) I run the tires at 80 psi. This way I have a little leeway with loading.
If You do weight each tire and go by the pressure required, You will have to add air if You fill the water tank ( unless it was full when You went on the scale). It's just too much of a hassle for me, I just regularly make sure there's 80 psi.

Don't forget to check the spare.

Check the VIN sticker on the outside left front of your rig. Mine has the VIN weignts and tire pressure listed.

Hi Wayne and Cathy,

we also own a 3400RL and yes you should run 80#s in your tires. There is a small tag on the street side above and left of the propane door. It has all the tire info listed for your fiver.

We run ours at max. Lower pressure builds more heat. I suspect a lot of blowouts are due to the pressure being too low, causing the tires to get too hot. On a hot day that's just asking for a tire to blow. I would think also that those tires get a lot of sideways stress in sidewinds, turns, etc. So we just keep them at max pressure on the trailer.
