need some info on filling tires with WWF or RV antifreeze

gunner76 · Jul 7, 2017

I want to fill my tires myself because the local tire shop only has Calcium Chloride and I refuse to put that stuff in my tires. I went to TSC and got this adapter kit and wanted to make sure this is the one everyone is talking about. Here is a picture of it.

I also have a few questions.
Exactly how does this setup work(if it's the correct one)?
How much WWF or RV antifreeze will I roughly need to do a set of 305/60/12 rear tires
How much air pressure should I be running with fluid filled tires?
Are there any other special items I need before attempting to do this?

if you have a "12v on demand pump" for a sprayer. that can make a nice way to help pump fluid into tires. there are other pumps, out there as well.

as far as the adaptor kit.

rotate tire, so the valve stem is at 12' oclock position.
you take the plastic cap of the tire valve stem
then you need a "tire core valve" tool. if you have a can of say "fix a flat" or some off brand of it. normally they come with a cap or little tool that will acts like a "tire core valve" tool. just insert tool spin it a couple times, and the valve comes out of the valve stem.
attach adapter, and what ever pump you are using to adapter, and then to the valve stem.
start pumping away, every so often, you turn off pump, hit the "air bleed" to let air pressure out of the tire, then turn pump back on to continue pumping in fluid. and just repeat this step till you get the fluid in. EDIT: SOME you run air bleed hose back to bucket or what ever you are pumping from. and air/fluid will go out of air bleed hose back into bucket. and you just leave pump running. and no need to keep turning pump on/off and letting air out of tire.
tire is full, when fluid reaches the valve stem. i want to say 75% to 80% full is what it comes out to be (do not quote me on percentages)
i generally fill tire up to valve stem. then use the air bleeder, to let out excess fluid. so when i check tires for air pressure later on, i am not squirting a bunch of fluid out.
put valve core back in. with valve core tool
adjust air pressure

the air pressure, read your operators manual for tractor. it will detail and recommend what to set tire pressure at.
but with above many folks run much lower than recommended for traction say 12PSI to 16PSI. not always, for example backhoe is on back of tractor. and operators manual most likely has a statement of running higher PSI for certain duties.

==========
to note it. double check operators manual. for both front and rear tires. normally rear tires can always be filled. but there are cases which it is not recommended, front tires filled with a fluid, can be a big no no on some tractors and cause damage to the front end, and most likely will see a statement in the operating manuals for that.
==========
suggest editing your TBN profile to add type of tractor / unit you have. so folks have a better idea of what you need help with more directly.

I used a $6 drill pump from Home Depot. The pump is a cheap plastic piece of crap but it worked. It won't pump into much of a head pressure so you have to let mosto (but not all) of the pressure out of the tire. Make sure it is jacked up so the tread just barely touches the ground. YOU DO NOT want to break the tires bead, so don't elevate the tire too much, you don't want a mess of fluid to come out around the tire bead. With the wimpy pump, I had to burp at every 2 gallons. consult the firestone fluid table on the internet and find your tire size to now how much to put in for each tire for 75 percent fill. Also go over the other posters instructions so that you understand every step so you will know what to do and when to do it. It is all just common sense.

OH, if some of this didn't make sense, just ask, we will help.

Thanks guys. I've changed a lot of large truck tires so I have the core removal tool and even have the bead seating tank if worse came to worse, although on smaller tires I've had good luck in the past using a ratcheting strap to seat the beads. I just wasn't sure if I needed a pump or something for moving the liquid, I didn't think the adapter kit I bought was everything I needed. I'm not going to fill the tires until later this summer, just wanted to get everything lined up now.

The only time you don't need a pump is if you are going to fill them with tap water, then you can use the 60 psi water hose. BUT since you seem to live in Iowa, I doubt that is going to be an option for you.

Straight water is not going to work here. well, it would but the ride could get a little rough in the winter
