inflate tire with rim guard

[tony binkowski]

can anyone tell me how to inflate my tire that has rim guard in it? i know the stem should be at the 12.oo oclock position, but do u need a special air chuck???

nope,

You might find it easier if you jack the tractor...and you'll want an air/liquid pressure gage (spring loaded so it's pushes the liquid back out).

That's a new one to me. Can't imagine why 12 o"clock and read the air pressure in the air pocket above the rimguard won't do it. Not up to your usual standard RJ.

Less weight on the tractor tire, less air/liquid mix coming out. Try it sometime.

RJ - I was going to confirm what you stated because I swear that is what Firestone told us - we use all Firestone tires on our USA built Cat soil compactors, bit I checked their on-line guide and found this

Hydroinflation Procedure for fluid Ballast
6. Inflate the tire to seat the beads, not exceeding 35 psi (240 kPa). With the valve stem still at the top, bleed the excess fill down to 1-2 psi (7-14 kPa) above the recommended inflation pressure.
7. Finally, rotate the tire and wheel assembly so that the valve is at the bottom of the tire. Set the final operating pressure with the tire mounted on the tractor and its full weight on the tire.

I can tell you that we don't do that at the plant. After setting the machine down, we check with the valve up. Our guys actually squirt a burst out before using the gauge to blow out most of the fluid in the stem because it improves air/liquid gauge life.

What you are really concerned about is air pressure. Air is compressable, liquid is not. It is the air bubble that remains after putting liquid in the tire that allows the tire to absorb shock.

I hear what you are saying and you are right about it but a tractor can't do any work with one wheel up on a jack. The pressure that counts is the pressure with all four wheels on the ground and ready to start a pull.
