I have a compact utility tractor with beet juice in one back tire and calcium in the other. Turf tires. The beet juicer sits flt on the tread on the concrete. The one with calcium that i just got back from the shop is so tight that the edges are up off the floor. It even causes the tractor to tilt toward the other side. I need to get this equalized. I know bout having the valve stem up. Do you use an elcheapo gauge and then toss it or is there a way to use my regular gauge without ruining it from the residue in the valve stem?

Maybe, let out a little air to 'clear' the valve stem then do the pressure check. ------------- Holding a grudge is like taking poison and expecting the other person to die |

| Use cheep gauge and toss it. They make a gauge for it, but you gotta wash it out afterm you use it. |

If the tires and rims are exactly the same, you can set up on level concrete, and measure height to axle center line, when that measurement is equal, they are pressure matched...

I always let air out till I know it’s low. then add air up to what you need as that way you are always pushing air in the stem and not back and forth. Always checking on the increase. ------------- I support the development of hybrid automobiles and alternative fuels as I need DIESEL fuel for my ALLIS CHALMERS! |

Do what John KC says... and thats the way I do mine... Let some air out, add some air and then check. I used a good gauge too... until I had it in my pocket while square baling hay and it ended up missing from leaning over to grab the bales. ------------- He who says there is no evil has already deceived himself The truth is the truth, sugar coated or not.

Buy the cheapo's from HF and then throw em away after they quit working! I've got a couple that I use ALL the time and they still register what they're supposed to.... I make sure that the valve stem is in the 12 o'clock position when I check. ------------- "Allis-Express" 19?? WC / 1941 C / 1952 CA / 1956 WD45 / 1957 WD45 / 1958 D-17 |

Dave I think the key words in your original post are 'just gat back from the Shop'. How much air did they put in? Must be Overinflated. With stem at the top, add some air to clean Valve Stem, then check pressure. Then adjust pressure to where you want it, adding a touch of pressure each time to clear valve stem. Gary |

Cheap pressure gauges are about as accurate as a Model T Ford. Buy 3 and they will all be different. I don't see how fluid differences would affect tire height other than density of the fluids. Personally I use a digital pressure gauge I got from Snapon, expensive but I trust it and a lifetime warranty. I have checked it with a known good manual gauge and it is dead on. I put antifreeze in the tires of one tractor and my skid steer. I get tire juice in it all the time. I just blow it out. Works fine. On a side note....this last week it rained for 4 days straight, total of 14". My driveway goes across a small creek, more of a run off. There is 4-3' culverts and 2-2' culverts. Normally not much of an issue but this this time I had a hole wash out the size of Volkswagen Beetle. I have several dump truck loads of very large rock on the other side just for this reason. Skid steer was the only thing narrow enough to get past that to fill it back in. I picked up a sheet rock screw in a tire midway through the process. Took it home and shoved 3 plugs in the hole. No other choice at the time. Worked fine till 2 days later and left for work (keep the skid steer in the garage) and see a piss stream of antifreeze shooting out of that plug under 80 psi, about 3-4 gallons. Got a plug patch put in it later that day. Good times. |

| Rinse the gauge with water and spray it with wd40 or something like that. |

The "hometown" tire shop I used to go to would let you mill around it the shop while getting your tires reapaired/replaced. I know they would run the pressure WAY up when setting the bead then let air out to the right pressure. Maybe your tire shop forgot to set the correct pressure after checking the bead seal. That shop closed up a few years ago and I now go to a place where customers are not allowed in the shop and you get to look through a little window to see what they are and are not doing to your vehicle.

| In the older tractors used for puling implments it was12 psi.Later with pick implments they used 16 psi. |

well I finally got with it. got the stem at 12, gave it a shot of air and let out a couple of blasts. Gauge worked fine and stayed dry. yep the high side had 22 and the low side had 6.  13 seemed to be right on the money and now she sets level. |
