Tires slowly leaking

Okay, I'm interested in the anti-freeze trick. How much do you put into the tire/tube and how do you get it in through the valve stem? I have a couple of Harbor Freight tires/tubes on a hand truck that leak, so I'm interested.

Just a few oz's 4-6 for most tires. you only need enough to coat the inside of the tire (or tube). Put it in a little squeeze bottle then install through the valve stem after you remove the core ;)
Anybody ever have to patch a tire or tube after somebody put some of that green slime stuff in it and it didn't work ? :eek:
Give it a try, if it don't work your only out a few oz's of anti-freeze and 10 min. of your time

FYI Don't ever use that slime in some Modern Car tires without checking first. It will kill the sensor in the valve stem for the Tire Pressure Monitor System (TPMS).

Gee I'm amazed how well my car tires actually hold air --better than I would have suspected with tubed tires.
 
A couple of people above have referred to the seams in tubes. What seams? There are lines on the outside of the tube left by joints in the mould, sure, but they are NOT seams in the tube. Think about it. If a seam were required, the tube must have been made either in more than one piece or "open". They are not. The "rubber" is of uniform consistency throughout. Thickness may vary but nothing else.
A very common misconception.:eek:
 
I can't see using calcium it tractor tires as being illegal, they use tons of it on the roads in winter all over the country, not to mention in other parts of the world as well.
 
My tires never leaked air with the rubber stems but after buying new tubes with the metal stems they go down about 5 lbs. in 2 weeks.

Last fall I put on 4 new Firestone tires. Replaced tubes with rubber stems and all tubes came with valve stem valves.

All 4 tires tend to leak down in a month from 35# down to around 28#

Since all 4 are going down at about the same rate.... I am guessing it is the valve stem valves. (My spare which was not replaced holds within 2 lbs all year.

Has anyone else ran into this and if so recommendation for a replacement valve would be appreciated.

Thanks

Plenty of posts re this subject and it puzzles me as well. Tubes are metal stem some older than others. Same issue ?? Inflate up to 35 and within a month all 4 are down to 28 or so. Never any lower than 25 yet never stay at 35. All 4 same thing. One of life's little mysteries I guess.

Barry, are the stems vulcanized in the tube or the original style bolt in metal stem?

The tubes came complete with the metal stems attached, they probly were vulcanized, I checked the pressure yesterday after 2 weeks and they were all down somewhere between 10 and 15 lbs. I still like the metal stems and the tubes looked to be well made, just have to check them more often I guess.
 
Slime is garbage! I've put it in small tractor tires and they held air for maybe a a month or so, then they were just as flat. Fix it right! Get a new tube and replace the old one. I don't was to start another war of words, But the ones I get from TSC have been all right. Maybe someone has different experiences. Also, I bought four new tubes from Smith and Jones several years ago (I don't recall what brand they are) but i've only added air once.

What Terry said
 
Of the four tires on the ground with late 80's air in them, only one loses 3-4 lbs annually. Some are metal stem and some rubber stem (It's a driver:D).

I agree with Terry about the slime being junk. It didn't work in my bike tire either, but sure made a mess. Some tire stores charge extra if they have to deal with the mess it makes.
 
I use slime on lawnmower, wheelbarrow, trailer, etc tires. Works great for many years. Use some common sense, if you have a nailhole, it won't work. If you have a slow rim to tire bead leak slime will work well. After some time (years) it dries in the tire and is no longer slime but more of a latex.
