Filling rear tyres

[Paul Allwood]

When I made the bits to adapt the skid steer rims to fit the back of my B7200 I drilled an extra hole in the rim to add a second valve. My idea was to use one valve to let the air out as water entered the other valve from the hose.

I had watched videos using the standard adapter that most of you probably have and wondered if I could avoid having to keep doing to turn the water off, press the button on the adaptor to release the pressure built up from the water.

I filled both back tyres today and it worked well.

It went like this:
- Rotate wheel so valves are at their highest point,
Remove both valve cores
- Connect the hose to one valve and turn on,
- Sit back and wait a while,
- When water started dribbling out of the open valve turn off the water supply,
- Re-insert both valve cores and inflate to desired pressure,
- Re-fit valve caps.

Since I might put water in these tyres once I estimate this has saved me about 4-5 minutes of of the next 10 years.... Less time than it took to drill the extra hours and type this post

Not sure if deflated large tractor tyres are prone to de-beading. If they are, this might be a problem as during this process the tyre is completely depressurised.

It's not the most earth shattering thing you've ever seen, probably not even earth shattering at all, but I'm happy when any idea works.

Brilliant idea. Even though it only saves XXX amount of time it's the problem solving and building that creates the enjoyment in a project.

I would have rigged a shut off valve in-line on the hose right before the adaptor and used the button on the adaptor to relieve pressure - since my fabrication skills and tools available are not as nearly as advanced as yours or others here on OTT.

You could have supported the rear axle to prevent the tyre being flat on the ground. This would have also added a bit of water in the bottom.

Great idea with the second valve, I think. Makes the filling level very defined in a short amount of time.

Thanks Hugo. I did have each side on a jack when it was filled.

Old time farmer 'cheat'. Raise wheel off ground, turn valve to 10 oclock, remove valve, add water. check...if no water comes out , add more, if water comes out, wait until it stops , insert valve, add air.
