13.6 - 28 tire pressure

Poland10 · Nov 1, 2019

Anyone knows what PSI should have in them?

Not knowing what you?re doing with the tires, I can only guess the proper air pressure. 12 psi is pretty standard with a usual range of 10-15 psi. Your tractor manual should say for sure.

Depends on the application.....most farm applications run from 10 to 14 psi. Front tires, rears, duals, loader tractor....these determine pressure.

Weight of tractor first, then any cast weights, then any mounted implements on a 3 point hitch? These all make a difference.

Like the others said... also, bias or
radial?

For pulling a hayride they should be at one pressure. For a mounted plow or tiller they should be at another. Just put some air in them until they look about right. If they look a little soft, put more air
in.

Put enough air in them so the outer edge of the tread bar is around 1/4" off the floor. I'll bet this will be close to 15 psi too.

Like Flying Belgian said add air till they look like you want them to. If soft add more air.

In the years since May of 44 when first rubber tires on tractor were had never has a guage been used on any rear tracror tire.

(quoted from post at 15:29:25 11/01/19) Put enough air in them so the outer edge of the tread bar is around 1/4" off the floor. I'll bet this will be close to 15 psi too.

When the outer part of the kleats raise off the ground, you have TOO MUCH air in them.

every tractor will be a bit different based on tire size and weight. so on bias tires, air them up till the budge on the side is just gone, but the cleats are flat on the outside edges, touching the ground.

too low and the budging will wear out the side walls with cracks, too high and the center will start to crack and the cleats will pull away from the carcuss and you also will have lower traction. Cleats should run flat on ground for best traction. And traction is what it was all about to begin with.

If you change loads, you may need to adjust the air a bit. If the tires are bit oversized, they will probably run at lower inflation, where smaller tires will run a bit higher. but 8 to 15 lbs is normally the sweet spot, with 10 to 12 being most common. ymmv.

Radial will be a bit different as they are designed to budge a bit.

I have them on rear of 1966 ford 3000. I do not have weights but they are filled...I have a bushhog and a snowplow to use on back. I now run 80 psi ...so I guess I go by looks.....Thanks
