Tire psi

2023 Flying Cloud 28

Goodyear 15” wheels/tires

Rated 80psi max. Dealer recommended 80psi. Interested in what others recommend.

60 psi

I think you need to look at the charts available on the Goodyear website for your tire to determine what makes the most sense for you, based on your load. Dealers will always recommend the maximum pressure, which provides the greatest load capacity. It’s unlikely that you’ll be running at the maximum load for each tire. A slightly lower tire pressure will reduce the load capacity for your tires, but it will provide a smoother ride.

I ran my 15” Goodyear Endurance tires at 70 psi on my 23FB, and this seemed like a good trade off between load and ride quality.

I recommend a tire pressure monitoring system too. There are many good choices available if you need one. It will greatly improve your peace of mind while towing.

The sidewall explicitly says maximum pressure; the manufacturer’s tables imply minimum pressure. Optimum pressure is somewhere in between, and for you to decide.

The Search feature on this site will lead you to numerous threads discussing this topic.

Here’s an example of the chart I mentioned:

[field & stream]

The manufacturer’s tire pressure chart Dennis provided illustrates the range, and makes me wonder why Airstream recommends the maximum. Maybe liability concerns.

The chart shows 80psi is good for 11,000 pounds over the four wheels, while your trailer will be less than 8,000. For your trailers weight, the chart shows only 45 pounds for minimum pressure.

Seems to me the consensus here is in the 60-70 pound range. Enough to provide control and reasonable tire wear, not enough to beat up your trailer.

Lots of posts here on this subject; you can Google this topic or go back on this site and look up. I know have 57K miles on my 28'. This is my second set of GYE's on my 28'- installed these last April- 15K miles. The GYE's are providing excellent wear and reliability vs the older GY Marathons. Plus, they work on standard 15" wheels that most AS's have stock. Running below MAX PSI of 80, is what many of us recommend, including GY. You should weigh your rig, and look up the weight recommendation on their charts so you know what you have, but I run at 58-60 cold. They do heat up to 90+ in summer heat here in TX- can you imagine what they would warm to if you started out at 80PSI cold?

I used to have broken latches, popped rivets, broken closet door, broken shower door hinge type issues, until I lowered to 58-60 PSI cold. Talked with several folks at AS factory during my visits last couple years in JC, and also talked with GY techs; recommendation was running between 60-70 PSI cold...never max PSI..since I lowered to around 60cold, no more issues. And, no additional tread wear...which is what I was concerned about. GY Techs said lower PSI (like 60 cold) would not affect tread wear.

Lots of threads on this subject. I have a tire monitoring system on my 23'FC and I found that 70psi is fine. The tires will heat up and the pressure will increase to be between 75 and 80 psi.

running 75 lbs. on both the single axle Bambi with 16" Michelins and on the 23FB dual axle with 15" Nokians.

I have run at 80 lbs. but decided to take the edge off a bit. Seems to work for me.

[Daquenzer]

I run about 75 lbs. It’s probably a little higher than necessary. It just gives me a little time if the pressure is dropping due to a leak to get off the road. Definitely get a TPMS. There are numerous types. I haven’t any issues with popping rivets.

[1StreamDream]

I run about 60 psi, fewer popped rivets and the chart shows me solidly in the “safe” margin for my weights. I would double check your tires to confirm if you have load range D or load range E … (I have E) they have different max psi rating and different load carrying ability, and there’s plenty of each out in the world. Don’t trust the manufacturer GVWR sticker, I would verify the tires that are on the trailer.

[StuartsDad]

I run 60 psi cold.

[Hans627]

After much study and discussion with tire people and AS people I've settled on 65 psi.

[Fungus]

58-60 PSI on my 25FB International. Only 13K miles of experience on one set GYE. Rolling over some of the 2500 miles of rough roads we just traveled I can only imagine how many more rivets I would have replaced (beyond the four interior rivets) had the tires been inflated to 80 PSI.

The wheels (rims) have an upper limit too. I have one unofficial document that says the circa 2017 Sendels max out at 65 PSI. But nothing official to be found.

[AlbertF]

Our single axle 22FB scaled at 3900 lbs on the axle with a full load of water and stuff for a two week trip.

I have the 15” Goodyear Endurance tires inflated to 55 psi. That’s supposed to provide a load capacity of 2270 lbs per tire. No issues, and far fewer interior pop rivets to replace.

[mpsgolf]

There are a gazilion threads on this and at least two gazillion opinions. I have a 28’ and I run 60 psi.

[ROBERT CROSS]

Our GYE's told me they prefer 72-74 psi COLD.

Tires run at the optimum pressure for the weight/load will wear evenly. Tires over-pressured will wear excessively at the center of the tread area…. and those run under-pressured will wear excessively at the inner and outer edges of the tread.

The maximum load ratings on the tire sidewalls are the mfr’s specifications for a maximum load…NOT the maximum “safety factor” for psi ratings. In other words…. if 80 psi is put into the tire it can meet its’ max load design….BUT… if run on a trailer with less weight upon the tire ..it will wear excessively in the center of the tread because it is over-inflated for the trailer weight.
The ideal pressure will evenly-apply (lay down) the tread upon the roadway. This is how a tire mfr’s chart can be helpful as to how much pressure to carry versus the load.
Calculate or weigh your trailer to determine its’ weight and apply the corresponding air pressure in accordance with the tire-mfr’s chart.

[Spaggs]

Measure the inside, center and outside temperature of your tire tread with a pyrometer. Even temps across the tread is your goal. When you find a pressure where you get this, then that’s the pressure you should use.
If you have higher temps in the center, you have too much pressure.
If you have higher temps on the edges, you have too little pressure.
If you get three different readings, you need an alignment.

I just got a 2023 International 23FBT and dealer told me to keep tires at 50# cold. This sounds plausible according to the chart.
