Ural Tube Replacement

UPS showed up with presents! The new heavy duty tubes from Heindl Engineering for my Ural arrived. I ordered two tubes, one to replace the failed tube on my rear tire and one to replace the spare tire tube. The HD tubes are much thicker than OEM, so the OEMs make better spares to carry around.


These are the tools I used to replace the tube:
-Two tire spoons  (three is better)
-Some windex
-Some tape

Step one was to review the following three videos to the good tube replacement tips and technique.

Step two follow the directions from the video to remove the old tube which was a 4.00/4.50-19

and replace with the new one which is a MSR HD 110/90-19 tube with a TR6 valve stem.

I also added a bit of tape on the inside of the rim to hold the rubber spoke protector in place.

Inflate the new tube to 40psi and let it sit for a bit.

The new tube install complete with no pinch flats!

I will swap the tube on the spare tire after a few days. I want to make sure I don’t have any problems with the new tube first.
I took the old tube and put it in a big tub of water to find the leak. You can see the little air bubbles escaping in the photo below.

I first found the leak, and then put tape around it to make it easier to photograph later. It was a very small cut and difficult to see. It looks to have been caused by the spoke nuts, so I am glad to have put the tape over the rubber to hold it in place in the future.
