Tires How many gallons do rear tires hold?

Skinnyman · Sep 9, 2009

I am getting ready to fill my rear tires on a CT235. Rear tires are 15"x19.5", GP tires. Anyone know how many gallons each tire holds. I want to add antifreeze and protect to a zero degs. Thanks for any help you can send me.
I am hoping 2 gals. of antifreeze per tire and fill remainder with water should protect to zero degs.

I believe I put about 29 gallons per tire. I got that figure from one of the tire website for that tire size for my CT225, same tire as you. I used 1.64 a gallon -20 WW fluid, I think that is cheaper than antifreeze. One bit of advise, re-seat those beads good before you start, I had some leaks and I had to raise my pressures to stop them and them add some more fluid. I lowered my pressures back down and no leaks so far. Get a good pump, my drill pump was a pain.

Thanks for the reply. One question. You said to reseat beads before I start.
I assmue you mean to reseat with higher pressure after filling and before using the tractor. Thanks again for the tips and info.

Actually, I would re-seat before I started putting fluid in. I got about half my fluid in the left tire and it started shooting streams out of the inside bead. I put the valve stem back in and started putting air in until it quit.

You can buy an adapter that lets you fill through the valve. I don't think it would be any quicker but it is an option. It does keep you from breaking the bead seal.

My plan is to jack up tractor just enought to take the load of the tire. Rotate valve to 12:00, remove valve stem. Add antifreeze with hand pump, then fill remainder of tire with water. I will use the adapter from NAPA auto parts that hooks to garden hose. Replace valve stem and inflate to proper pressure. If I am going about this wrong please jump in a save me from myself. Thanks folks.

Just finished filling both rear tires. Job went real well. Could not believe the difference it made. Thanks guys for the input and help!!!!

How long did it take and how much antifreeze/WW fluid did you use? Was it a total pain in the ... or not too bad? I have the same tractor/tires and have been thinking about doing this too.

Thanks,
Patrick

Was not problem. I went about it just as I posted in post #6 above. I bought a hand pump to pump in the antifreeze, cost 12 -14 dollars at auto parts store. Rubber hose of hand pump would slip tightly over valve stem.
Added water using adapater that threads on to valve stem. I pumped the antifreeze, 2 gals. per tire in less than 10 mins. Not near the problem I anticipated. Good luck. BTW, the pump is called a Koehler "transfer pump".
purchased at Auto Zone.

Skinnyman, did i read right you only used 2 gals of antifreeze? Was that enough? Just curious

Skinnyman · Sep 14, 2009

Don't know. I live in NC on the coast. Very seldom does it get down below 20 degs. F. 27 gals. of water, 2 gals. of antifreeze per tire, I figure I'm good for about zero degs. Easy enough to add another gal. or two if need be. If anyone thinks I need more antifreeze to protect to zero degs. please let me know.

Pretty sure you will want to get to at least a 30-40% mix antifreeze to water (rough guess) to protect to 0 deg. I checked out a few web sites with specs on antifreeze and they all seem to be within 10-15 deg. of each other in a 40/50/60 mix. 40% is around 0 deg, 50% is around -25 to -35, and 60% goes down to -60 or so. Here's one: Prestone Low Tox Antifreeze Specifications

I am planning on doing this myself in the next few weeks. I'll post back when I get it done.

Have you guys tried Rim Guard for rear tire ballast?
Rim Guard is nearly 30% heavier than water.
Rim Guard is non-corrosive.
Rim Guard is non-toxic and biodegradable.
Rim Guard is freeze-resistant down to -35ｰF.
Rim Guard is cost effective because inner tubes are not needed and tires are easier to repair

I just used 22 galons of plumbing antifreeze to do my two tires. Its enviro and cheep about $2 a gallon. I think it is made from the beet juice stuff. works great and good till 50 below. If it does get that cold here I'm on an iceberg and paddling to california.

I haven't filled my tires yet, but have seen posts about Rim Guard. Most people were worried about corrosion of the rims using other standard solutions. It doesn't get too cold in Ca., but it does on my Oregon property.

Regular auto antifreeze is also a corrosion preventer. Every once in a while we will get a -10 deg. day here in NE Ohio so I am planning to do a 50/50 mix. Then I won't have to wake up at night wondering if my tires have exploded or not

What is the purpose for filling tires with liquid?

Stability, weight and traction. It lowers the center of gravity, it adds unsprung weight(meaning that the tractor is really pulling the weight not lifting it), it increases traction which is a major benefit, as power is useless unless it can be put on the ground. Steel plates can also be used to increase weight. I used winter -20 windshield washer fluid at about 8 lbs per gallon. Some use beet juice that is about 30 % heavier, ag tractors have used calcium chloride for years at 12 lbs per gallon but is very corrosive and needs tubes.

Any idea how many gallons I would need in my 440's GP tires? GP Tires - 10 X 16.5, 6 PR, FRONT; 14.9 X 24, 8 PR, REAR

First, don't fill your fronts. With the loader it is unnecessary and it is hard on the front ends parts. According to this page at tractor smart it will take 47 gallons.

Here is the one for GP/R4 tires
