UNBIASED opinion

Question on innertubes. I know there's a difference between radial tubes and "regular" tubes. But what IS the difference? I know you need to use radial tubes in radial tires. But should you use radial tubes in BIAS ply tires? Why/why not?

Enquiring minds want to know

I don't know what the differance is. But I just put a new tube in the rear tire of my JD. Tube said on it, "for use in radial or bias ply tires".

Where did you come across said designation of two types of inner tubes? Just curious. I'm thinking there's not a radial type tube, thus I ask what prompts you to ask?

:tiphat:

Do you even need to ask? You have more experience with equipment; and have forgotten more things; than many of us will ever know.

Is it a safety issue if the tube fails at 3 MPH? Mostly it's just a PITA.

That deliniation is for high speed street use, rather than for farm use. It's also rather outdated. Many of us used to stretch the life of our pickup tires by sticking a tube into it. With better tire strructure and improved infrasructure, people go for years without having a flat.

Ah.... But there IS a radial tube. Radial tractor tires are marked with instructions to use ONLY radial tubes. Last case of tubes I bought (13.6x28/14.9x28) were marked as 136/14.9R as a part #. Marked on tube "For use with radial tires". Mainly I wanted to know if it's ok to use radial tubes in bias tires.

Well, I'll go along with the fact that I've FORGOT a lot. Question is, how much did I know in the first place?

Radial tractor tires are marked to use ONLY radial tubes in radial tires. Also seems most tractor tubes nowdays ARE for radial tires.

And, uh, by the way, you're talking with a guy who's had THREE flats so far this week.

The way it was explained to me was the radial tube in a radial tire converges into a common center. There for easier to balance.

If you put a bias tube in a radial tire or radial tire with a bias tube you get that criss cross wobble which is impossible to balance.

Do what you want but I'd stick with radial radial or bias bias but I'll admit I'm biased.

Edit: I don't have a clue. I thought it was a joke

Here's the link
Tubes

Here's a quote from said link

RADIAL-TIRE TUBE- The construction of an inner tube for use in a radial tire differs from the tube used in a bias tire. A radial tire flexes in such a manner that it concentrates the flex action in one area and at the edge of the belts in the shoulder of the tire. This concentration of stress will damage a standard tube causing it to fail. To overcome this problem, the radial tube is made of a special rubber compound that is designed to overcome this concentrated stress; Therefore, standard tubes must NEVER be used in radial tires.

I think it would depend on application. I don't think all I've learned about car/truck/trailer tires applies all the time to tractors (for instance rotating tires).

The guy I was hoping would respond! Thanks!

I've got one tractor with radials. We sliced the sidewall open on it 2 days ago. (6" or 7" gash" from bead out to tread) I ordered a new tire and tube. I've also had a rash of flats on 2 of the smaller tractors in the last few weeks. (Both run 14.9x28" bias ply) I bought a case (6) new tubes. What I got is a box of radial tubes. After closer examination, the box says "for radial OR bias ply tires". I've got 2 of them in tires now. The ONLY thing I can see is the radial tubes are smoother and slicker than any tubes I've ever seen before. That, and they ain't cheap either.

Farm,

While it is expensive, have you thought about foam filling the tires on your mowing machines? The price of the foam is probably less than the down time you have from all these flats....

just a thought.
