Do I have tubes in my tires?

[draku007]

I have a leak in one of my rear tires - Goodyear 41x14.00 20 NHS. Do I have tubes in the tire or will I need whole new tire? I can't find much details when searching for the tire and I don't see any tubes anywhere.

If you don't have a tube in your tire your local tire shop will be happy to sell you one.

I tell the difference on my Kubota M6040 by the type of valve stem. The front tires are tubed - the stem is all rubber and can be pushed side to side and in all directions. The rear tires are tubeless and have a rigid metal stem.

Post a picture of your valve stem.
Tubes made for liquid fill and many but not all tubeless valve stems both have retaining nuts visible. Most tubes use plastic nuts, tubeless valve stems using nuts are usually metal nuts. Tubeless stems not for liquid fill are usually all rubber. None of this is without exception.

This is the 16.9x28 - RimGuard filled - rear tire on my Kubota M6040. It's tubeless. I will get better pictures when the sun comes up and the temps get somewhere above 15F. This shows the metal stem and metal securing nut.

Holy Cow - it's really cold outside. Anyhow both my front & rear valve stems are rigid. They are held in place with screw down nuts. The silver top one is on the rear tire - it's tubeless. The black top one is on the front tire - it's tubed.

I will take a picture of the valve once the snow melts here in NJ and I蛟､l post it here.
Thank you all for the input.

Here is my a picture of my valve. Looking at the pictures on the previous post I think I have tubeless tire.

Yes - looks exactly like my rear tire tubeless valve stem.

No doubt.

I am surprised that Kubota put rims on your tractor that do not have valve stem guards.

More do not than do.
