An Unusual Problem with Tire Inflation (Page 3/3)
Dennis LaGrua DEC 02, 09:43 PM
For people that want their own compressors for tire inflation, the state of the art has really improved in recent years. I have a cheap portable 12V Harbor Freight unit that I carry for emergencies. It can inflate a tire from 20 psi to 35 psi in about 2-3 minutes. The 5 HP 230V compressor with 60 gal tank in the garage set to 120 psi can inflate a completely flat tire in less than 15 seconds.

Is that with the weight of the car on the tire(s)? The reason I ask, is that in addition to the 120v compressor that I discussed above, I also have an awful 12v unit. This 12v compressor seems to struggle unless the car/tire is jacked up off of the ground. I acknowledge that perhaps it's just this particular compressor that sucks (figuratively speaking ), but it's discouraged me from ever bothering to use a 12v compressor again.

I have a $20 unit I got at pep boys a decade ago. Never had a problem and I have 12 tires to maintain. Takes 2 minutes max per tire to top off from 28-35 for instance. I thought everyone had one of these? Gas station is fast only takes like 20 seconds per tire lol.

Dennis, how did you remove the valve stem from the tire with the tire mounted on the rim? Thought you had to have the tire off to get the valve stem out.

Turns out that John Deere adds water inside the tire for ballast, to keep the tractor from overturning.

Not just JD but a lot of other slow moving things have "Loaded Tires."
(Likely installed by a dealer not the tracker factory.)

⚠️ Warning: Often isn't just water.
Most uses Calcium and water and maybe Antifreeze in "up north" states.

Many "trackers" have Loaded Tires and Wheel Weights and more. "To keep the tractor from overturning" is unlikely reason for most. More like to get more traction.

There are tools to replace rubber stems w/o removing the tire but not recommended by most stem makers.

Won't help w/ metal stems w/ or w/o under inflation sensors.

If careful w/ normal tires, often can break just outer bead to fix the stem w/o causing balance problems.
Run Flats and very low profiles isn't normal and can fight you trying same.

I had to buy wheel weights for the rider mower I was using on a relatively large property that had quite an incline in some areas. I found that without heavy iron wheel weights up front, the mower wouldn't turn when going uphill!

Valve stem just unscrews with the proper tool. Whenever you have a tire changed this is the first thing that is usually done. I carry the Harbor Freight 12 V Compressor when on the road. The one that I have costs $37.00 and inflates pretty fast. In the garage we have an old Campbell Hausfeld 5 HP 220 V 60 gal stand up compressor. That inflates tires as well as the service station units because it is a pro model compressor.
