Tires Checking air in filled rear tire.

[JDL538]

Can anyone tell me how you check the air in a filled rear tire, everytime I try
the antifreeze comes out, with no reading.

When ever I check the air in my rears I always make sure the valve is at the top of the rotation(to the sky).
If that doesn't work you might need to bleed some fluid, I don't think the entire tire needs to be filled, or should be filled.


Hope this helps.

Yep, what he said. Don't be surprised if some fluid comes out, even wwith it at the top.

Just lick the Rim Guard off the gauge!

as others have said, stem at 12 o'clock, fluid should only be to the top of the rim at this point. then depress the air valve just enough to release the fluid captured in the stem, hose off with water, then blow out with air. repeat as necessary. if you have calcium chloride as ballast, it's corrosiveness will rust your rims and ruin your air gauge.

you need a dial type gauge. they work fine with fluid. Your gauge will read higher at the bottom of the rotation circle. If you are using a corrosive fill the gauge will have limited life unless you clean it, however good enuf 0 to 60psi ones are available from HF for about 2$.

Thanks all, who is HF.

As others have said, I always started with the valve stem at the very top. The next step (for me) was to give it one short blast of air to blow any of the liquid away from the valve stem. It might be even better, but not really necessary, if you put a jack under the axle and take the weight off the tire. The other thing is that there are air/liquid tire gauges made specifically for liquid filled tires and they really aren't much, if any, more expensive that the regular, air only, gauges.

Harbor Freight Tools. there are a few threads regarding them on TBN.

This is how I do it, especially if I know I will need to add some air and must use the little compressor I carry in the truck.

I'm pretty sure tire pressure dosen't change with wieght on it, so jacking the tractor up makes no difference. I don't know the scientific reason for it. But I'm guessing it's because the sq inch (volume) of the tire dosen't change with or without wieght.

Hi,
Bird is correct. If you take the weight off the tire it will round off or droop a little allowing the fluid to back away from the valve. I almost always check it this way and very seldom lose fluid. Think about it, the weight of the tractor will cause the tire to flatten out on the bottom and raise the fluid level in the tire. The tire should be filled to the top of the rim and the valve at 12 o'clock to check pressure.
Good Luck,
