Good Year Tires - Why Tubes?

[AndrewSpencer]

So, I should have asked folks before I did this but I did get a new set of rear goodyear tires. (maybe made in usa?)

They claim they are supposed to have tubes in them.
Why do tractor tire manufactures think this was suddenly a good idea? Bicycle tires are now going tubeless for the good ones.
What is it about the tire that necessitates a tube?

Could I throw a can of the bicycle tire sealant into one of these tires to make it tubless?
Bicycle tire sealant is pretty neat, it stays liquid until it is forced through a small cavity, so it does not form the cement like the fix a flat junk does.

Thanks for any advice or thought you all might have!

This topic has been discussed on this forum many times in the past. You can probably use the search feature, upper right corner of this page to find these threads. One of the main reasons to use a tube in these tractor tires is that the design of the rim is not made to accept a tubeless seal like the rims for modern tubeless tire applications like autos now use. Some people have mounted their tires tubeless and have been successful. Personally I don't like to deal with the problem of cleanup of the sealant that is used in some applications when you have to deal with a flat. JMHO

Thanks. I will try searching again. For some reason, I never seem to find what I am looking for.

Tubeless agricultural tires are monuments to the stupidity of man.

You will find them on newer equipment with rims that don't have anything riveted to them. I don't like them because if a tire starts going flat, a tube will sometimes buy you some time to let you limp to the shop to change it. If it goes flat, you have a better chance of airing it back up and then get to the shop to change it. Tubeless tires will adhere to Murphy's Law and will just come off the bead and then there you sit.

Hi,
There's nothing new about Cub tires using tubes in them. Every Cub tire with ag tread since the beginning in 1947 originally had a tube in it, as far as I know.
My Cub, and every other one I have looked at with ag tread have tubes in the tires.

Someone was talking about it on here lately, he thought they used tubes because of the rivet holes in the rims, he thought air could leak out there.

The 13.9-16 turf tires from the Loboy days were tubeless. Can’t ever remember an ag tire that was tubeless. If they didn’t have tubes you couldn’t have used calcium chloride ballast. Salt water is far cheaper than antifreeze or iron.

I dont like tubes. Extra cost, and extra hassle! And have to exercise extra care with a tube, not to pinch it while changing a tire or patching a leak.

But like mentioned above I also thought the rim with the rivets was not sealed.

Also, thought I saw or heard in the past where a tire made as a "tube type" does not go through the same process as a tubeless tire. Maybe someone with lots more experience than me can explain that better!

I dont like liquid ballast either. Might be cheaper now, but those rotted out rims will cost more down the road. Not to mention if you service your own, you would need more stuff to deal with the liquid! And that calcium cloride burns too.

Wheel weights for me!

Here's the difference between a tubeless rim and a tube type rim. Tubeless is on the left. Tractors can take a lot of bumps and jerks in the field. If ag tires were put on without tubes and you hit a rock, or something else, the sidewall moves inward a bit and at the low air pressure in these tires you could easily get an instant blowout and there you sit.

Thanks for the picture, radioguy41. It has been said that a picture is worth a thousand words. The picture you posted shows exactly what I tried to describe in words in my post above and did it more clearly and quickly. Stan

In addition to the rims the lower suggested PSI I think makes it hard for the tire to stay seated. I have some tow behind mowers that are supposed to have tubeless tires. Driving over the rough ground it is impossible to keep them inflated. I switched them to tubes.

Yeah, I have a utility trailer that came with tubeless tires. Both tires switched to tubes after a couple of flats in the field hauling heavy loads.

Think of the gyrations and contortions the tires go through going over rough objects....rocks, logs ditches ...at lower inflation pressures. I also like that tubes in tires are more forgiving in that when ever I have had a deflation....Flat Out or Berrymans always works...I don't know how forgiving the tubeless are

To throw a monkey wrench in this discussion, ALL new tractors made in the last 25+ years have come off the assembly line with tubeless tires.

This will make some of your heads explode, but they even put calcium chloride in those tubeless tires! Let it run right up against the painted steel rims, and it works fine. Corrosion comes from leaks and exposure to fresh air. The air in the tire isn't fresh as long as there are no leaks.

Tube vs. tubeless is primarily due to rim bead design. It is possible to mount tires tubeless on rims that were meant for tubes. The tire guy did it with the new 20.8x38 radials on the original 1979 rims on my 1586.

Funny story, I discovered the front tires on my 67 Cub were mounted tubeless... using an entire tube of black RTV. Whoever did it gooped up both beads all the way around to keep the air in, along with the valve stems.

You can't compare today's technology to yesterday's tractors.

Sure I can. We've got two pages of guys saying how tubeless tires won't hold up on tractors because of the terrain they run on and how they are used.

The terrain hasn't changed.

Modern tractors go over the same terrain and are used AT LEAST has hard, and tubeless tires hold up just fine.
