Recommended tire pressure for 3t single axle trailer tires?

What should the tire pressure be in a 3t single axle trailer?

it depends on the tire (it should write on it how much PSI should be - I don't know how much the bar is 1 PSI, but if you have an inflation gun, it should write on the clock). I think that you can easily load 4 to 6 bar (for comparison, I have 3.3 bar in a passenger car and you can see that the tire "sits" a bit - new tires) On the other hand, it depends on how much you are carrying with this trailer, because the fact that it is 3 tons does not mean that 5 will not enter

Enter your tire size.

tire size 10./75-15.3

Maximum pressure 4.7 bar. P.

I would advise you to take into account what weights you will carry with it, because if it is empty, it will be even 2 bars, but if you load it with grain or earth or something like that, I guarantee that the 4.7 bar will not be enough.

It's as if the constructor calculated that there should be a 10A fuse, but you think that if you turn on all the receivers on this fuse, you guarantee that it will be too small.

if you have not realized yet that everything is done with spare, I will give you a very simple and real example - in my town there is a newly built footbridge intended only for pedestrian traffic (but only officially) - the constructor clearly stated that when a car would enter it it will break down. During the second flood wave after the river had subsided, there was a need for an ambulance to get to the "other side", but access was possible only through this footbridge and ... an ambulance passed, followed by a large fire engine and a few more passenger cars in the following days - and the footbridge as it stood it stands like that, so do not take too much of the maximum pressure value given by the manufacturer because it will withstand much more.

You misunderstood me a bit that it can withstand even 10bar, I have no doubts, but if it breaks and kills the peasant, each expert will check how much can be loaded according to the manufacturer and how much was in reality and I think there is no need to pull the thread.

There is also a difference for road and field tires - balloon.

I also have a footbridge and the cars drove on it and a post was placed in the middle and it's over now, the cars have to catch up about 6 km.

When stationary, the tire withstands higher pressure because there are dynamic changes in pressure while driving - e.g. when hitting a stone or other unevenness. Hence, some reserve is needed.

PS: I don't have a footbridge

Hello
these tires have a wider balloon and have greater friction, such as 9.00-20 (I think you have a 4t trailer), if you put on these 4-5 tons and at higher temperatures you will drive more than 10 km at a pressure of 4.7 bar then these tires will not withstand because there will be too little air and they will heat up (if you use the brakes on the trailer), this guarantees that the tires will tighten because there will be a lot of friction against the surface depends on the surface, because if it is bumpy, then too little air is not too good I will give you an example: I have a 3t trailer and I have 8,25-20 tires not too rich and I have 6-6.8 bar in them, I carry it with light loads and not far away and I do not use the trailer every day only once every 2-3 months. it says on the tires unless it is pumped up to 5.5 bar.
Write us what weights you will carry, we will write you how much you should pump the wind into the wheels.

2 to 4 tons

I think 5-5.5 bar should be enough for you. I have too one thing Axle on the wheels you have and I think I have 4.5-5 bars, but not such weights I am doing and that's enough for me, I drove it up to 2.5 tons, up to 3 tons

I will stick to the topic. I have 8.25 x 20 tires and I do not know how much air I have to load.

The line of thought is correct, but I would like to know how he checks it, other than saying that it was torn from the excess pressure. But how much exactly was it?
Inflating another one of the same type is not reliable, it could have been a different material or a different way of riding.
... And the pressure is gone NOW!

It's just aside from the discussion ...

The so-called balloon tires are usually used for field transport and the narrow ones for road transport. Someone wondered why? Well, because narrow tires have higher unit pressure and lower rolling resistance, and vice versa in balloons. The pressure should be as stated in the manual. Over-inflating the tire by 20% shortens its durability by about 40%, and not over-inflating it by 20% only reduces its durability by about 10%. So to sum up: Balloon 4.5 bar and narrow, e.g. 12.00 x 20 approx 6 bar. If I'm wrong, I'm sorry, but I don't remember exactly. Regards.

Sorry for the offtopic, but I will write about this clapboard 'for pedestrians'. The paddle must withstand such pressure that the car will pass over it without any problems. After all, if it collapsed under a car weighing 1.5 tons, what would be if 15 people weighing 100 kg entered the cladding?
And about these tires, maybe look somewhere on the manufacturers' websites.

I also had this post, but they tore it and threw it into the river

I believe that the discussion deviates from the topic - so it can close it, if no one has anything to write about it? I do not report - because which of the posts?

Hello. I didn't want to start a new topic, and I have a question about tire pressure. I have a two-axle trailer with a GVW of 2700. The trailer's own weight is 650 kg. The tires have a maximum pressure of 6.5 BAR. Tire size 195/50 / 13C. What should be the optimal pressure in the tires if I carry loads close to 2 tons?

Hello.
It is a car trailer or a tow truck.
You pump the pressure 2.5 bar.

Pressure max is written on each tire and it must never be exceeded.

Oh hell so little? Only 2.5 bar? I was convinced that 4 bars would be git.

The Polish bison has a nominal 0.8 bar in the front tire.

Well, but what a big balloon is there.

And here's the secret, balloon tires have a tiny bit of pressure. And the narrow tires have high tires, I have 4 bars in the access road.

and that is the minimum in a ride-on ride should be.

You have to see what the tires look like when fully loaded and while driving. I suspect that with such a low profile it will be better to have 4 Bar, or even 5, since the permissible tire pressure is 6.5 Bar.
