You want about 80 psi in them.

These are Bobcat tires, not truck tires. Look what it says on the side wall. Probably not anywhere near 80 PSI. My skid steer has 10:00- 16.5 and they are 35 PSI. I don't think a wider tire would be much more, if any. Dave

Look on the tire sidewall and it will give the advised inflation pressure.
I generally run the 10.00-16.5's on my machine at 50-55 psi and they say 50 psi on the sidewall. I'd think the 12's would be quite similar...

The owners manual says 30-35 PSI and refers to them as flotation tires. The original tires were 6 ply and the new ones are 10 ply, I think. I put tubes in them because if I didn't use it everyday, a couple tires would slowly leak. Very common on skid steers. Too much air and you won't have as good of traction and the ride will be a lot rougher. 35 PSI in the tires seems to work good. Bobcat tires are low speed off road tires. That must make some difference. My rear tractor tires are 6 ply and only take 14 PSI. My neighbor brought home a 644 JD loader and needed air in a tire and it only called for 16-18 PSI. That's a big loader. I did mention checking the sidewall in my original post. Dave

According to Bobcats Tire webpage they do offer flotation tires that use 30 and 35 psi. They don't show a 10-16.5 size in their brochure though. As you can see, most 10 ply rated Skid tires are to run 50 to 60 psi. Go to link below and click on pneumatic tires to the right. Charts is most of the way to the bottom. Thanks for showing me their flotation tires, did not know about them.

My tires might only be 8 ply. I just went with what the owners manual said and they work good. 12-16.5 could be 50 PSI. Most all skid steers come with the flotation tires on them already. Dave

To be honest I didn't know there was such a thing as a flotation tire for a skid steer.
It may well be an option but I've never seen any equipped with them around this area.
Most are either on 10.00x16.5's or 12.00x 16.5's, also known as sink quickly and sink slowly...
What sizes are they running for flotation in your area?

You don't hear of them called flotation tires because they are standard equipment 95% of the time. There are even wider flotation tires as well. On my machine (not Bobcat) which is a size smaller, the standard tire size is 7.00x15 and they take 50 PSI. The 10.00x16.5 take 30-35 PSI. Dave

I guess it depends on the machine...
I've got 10.00-16.5's on my LS170 NH and I can assure you, there's nothing flotation about them. They're the standard tire on that machine. Perhaps Bobcat's are different.
Mine call for 50 psi on the sidewall and are promptly inflated to 55 psi, with tubes. They're pretty squirly with less than 50 pounds air. I can't imagine running 35 pounds in these tires on this machine (1700 # operating load, 5500 # machine). It would be dangerous on this machine.
