Tires New R4's

[jd670]

Installed my new R4 take offs today. I found this complete set on Machinefinder a couple weeks ago. Brand new with rims. They still have the rubber tips on them. Upgraded from the 19-5 R4's.

 

[CH4Ohio]

What's the upgrade? Are these larger/wider than the original R4's?

Did you get a good deal? That's a smart way to buy tires -- dealers do a lot of swapping around with new wheels and tires. Takes some time to find them but it's way better to buy a complete rim and tire!

Very cool!

 

[jd670]

Yes. I think so. $1700 for the complete set.

 

[jd670]

Yes. They're the larger R4's. These are the 43-16 x 20 rears. I had the 15-19.5's before. I had one rear rim with some Calcium rust that was getting kinda bad. New rim from Deere was around $500. So, I started looking for replacements when I came across this complete set from Akrs JD in Seward Nebraska on MachineFinder. Ian was great to work with and went the extra mile to get me a great deal. I am completely satisfied. I had the rims ceramic coated for protection. I think I'm going to load them with RimGuard.

Find good find.

Why does people use this old calcium that destroys metal ?

I’ve completely filled all 4 tires front & rear with a weak antifreeze mix and water in 7 JD 4&5k series tractors.

No rust & non corrosive.

 

[jd670]

No sure why. Cost maybe? I'm looking at rimguard or windshield washer fluid. Just starting checking pricing on rimguard. My JD dealer doesn't do it. They send you to Best One tire. The quoted price for RimGuard is $4.75 a gallon. That's if I bring tractor to them. More if they come to my house. WWS is between $109-130 for a 55 gallon drum.

 

[Brown Dog]

Boy that rimguard would get expensive.

I added 20gals of AF to 70gals of water for each of my back R4 tires.

I think the fronts only held 36gals total.

I have a 110v liquid pump set up to fill mine.

I need the weight for traction & stability on steep banks here on my farm.

The ride is so much better too.

 

[jd670]

I have a pump and the adapter valve to fill mine also. I need the traction. My place is not flat either. Right now, i'm leaning toward the WWS because of price. I don't think the animals would drink it if I happen to get a puncture. I'd rather use RimGuard for that reason. I herd that Rural King sells RimGuard in bulk. I'm going to call them tomorrow to see.

There is another non corrosive alternative to rim guard. My dealer installed Bioballast before delivering my tractor.

Thanks. I'll look into it.

Cost and availability; the rim guard, bio fill are fairly new products.
Even now 50 pounds of calcium chloride is $15-20.
To fill a 18.4-30 tire to 75% is about 103 gallons.
A 3 pound to the gallon mix of calcium stays slush free down to -12 F,
bump it up to 5 pounds per gallon and it's good to - 52F.
So for a tire that size if you went with 4 pounds per gallon and 100 gallons of water,
8 bags of calcium would be about $120 and a person can easily do it themselves on the farm.
And the calcium used to be much less than that price wise.
So well under a $100 per tire to add 900 to 960 pounds per tire.

Your weak antifreeze solution in cold climates would destroy the tires.

…

I could simply add enough AF to each tire for colder climates.

No Way in the world I’d use that acidic calcium destroying my steel rims.

$700 of antifreeze is no big deal on a high dollar tractor that you certainly don’t want the rims rusting out on

Calcium filled to the correct level will not rust the rims. However, don't want to have any leaking tires either.

Rim Guard has been around for a couple of decades now.

 

[Grateful11]

Did you change the fronts and rears to larger tires?

 

[jyoutz]

Calcium filled to the correct level will not rust the rims. However, don't want to have any leaking tires either.

I don’t think that’s true. The correct level includes an air cushion. Calcium in liquid suspension that is in air contact will indeed rust steel.

 

[beenthere]

Calcium level above the top of the rim doesn't rust, steel is below the calcium level. Then as long as there are no leaks that allow the calcium to bleed onto the outside of the rim, no rust.
I'm not sticking up for calcium, but it doesn't deserve the bad rap from incorrect use either.

Well like I said fairly new, especially compared to calcium.

But what is the reason to stick with an old inferior product when there are new and improved products available?
