Trailer Tire Pressure

[squinko]

I just bought a Tentrax trailer and will be towing it with my Wrangler. The tire pressure on trailer tires are around 32-35 psi currently. I have noticed it bounces a little while towing on pavement so I plan on playing with the tire pressure a little to see where it needs to be to prevent it being bouncy.

What tire pressure are you running on your small trailer? I'm curious to see what psi everyone is running in their trailer tires.

Thanks,
Benny.

I run 10psi off road and 22psi on
Tires load range C
Trailer weight <#600 loaded

I run 20-25psi in my M416, depending on the load.

When I run to Moab (3K round trip all highway and loaded for 10+ days) I run 'em at 25, but for around home (under 200 mile trips) I run them at 20.

I have shocks, which help some, but when I ran them at 32-35, it bounced a lot.

Approximately how much does that trailer weigh ?

I run mine around 20, much less bounce on the street especially when unloaded.

I run mine around 20 - 25psi.

Man those tires look close to the fenders, do you get rubbing?

When I had the stock tires I ran 25, with the 33's I ran 32psi, the current tires have 70psi load range E on the factory rims, without tubes. No bouncing at all from it which surprised me.

I would have never put them that high, the tire shop did. Once I discovered it on my trip I just left them that way figuring I might get better mileage ROFL.

Current tires....

They do fit the well with 2.5" of clearance/travel,combined with 10psi the ride is smooth.

The Tentrax weighs about 600 lbs empty so I will be heavier than that when I tow it. I have 33" MTR's with a six inch lift on it. Sounds like 20 to 25 lbs might be the ticket.

Here is a pic (sorry it's a small pic)

Add shocks.

Bringing back an old thread as I was thinking about this. I have 32x11.5" MTRs (C) and I first had my tires set at 25 PSI. After driving down the first dirt road, I noticed the outside of the tires were not touching the road as the center was, so I took it to 20 PSI. My trailer is in the 500 lb. range when loaded, and has leaf springs and shocks.

My AT Chaser on 33's loaded with tent and gear comes in at around 1300 lbs, I run 20 psi using the chalk method. Off road I have dropped it down in to the single digits, only when it is a really technical trail.

My trailer is probably in the 800lb range when loaded with stiff trailer springs and no shocks. I run 10-12psi consistently in the 33's on the trailer. Tows very well this way with no bouncing except on big trail hits or RR crossings etc.

I'm not going to get much bounce off road where I am, the speed limit is 12mph on green lanes but on road I go around 18/20psi on 265/70x17"

Update... Last spring I added an RTT to my trailer, and I actually had it weighed when it was mostly loaded and it came in at about 1100 lbs. I had set the tire pressure to 20 psi, and as in the photo below, it looks like the psi might still be too high (assuming that more of the lugs should be touching the road across the tire)? I went ahead and went to 18, but don't want to go too low. Any opinions? (Tires are Goodyear MTRs, 32x11.5). I leaving soon for a trip out west... about 4,000 miles! There will be dirt roads and trials, but most of the miles will be on paved roads.

The setup:

Thanks...
