3 deflated tyres in the same day, Stop the compressor is glowing.

As the title suggests.

I keep getting stones and bits of crud inbetween the rim and the tyre which cause the tyre to deflat. It was recommended to me to have inner tubes fitted, did that and I now keep damaging the valve on the tube causing the tyre to go flat and no way of repairing it. I'm regretting fitting the inner tubes now and would much prefur to run with out the tubes. Is it best to glue the tyre on with a proper sealer or am I using the wrong type of vavle on the inner tube.

I'm running 30.5x 10.5x15, Im not 100% sure on this size by the way.



How can I stop this from happening.


Many thanks.

The best way is to get your self a set of bead lockers! or if you don't want to spend that sort of money, when you get your tubes taken out, use some tyre sealer round the rim. that might work.

Cheers,

If you have steel rims, weld a bit of steel over the valve stopping it ripping out in the sticky stuff:

What pressure are you running at?

If suitably inflated then getting crud between the bead and rim should be a problem, I've been running 33x10.50-15 tyres tubeless at around 20 PSI off road without a problem. If you are airing down tyres to very low pressures then bead locks will be inevitable to stop the bead moving on the rim.

When you say valve damage, is this from the tube slipping with the tyre on the rim, causing the valve to be ripped off?

I stopped at the garage before going to the site and inflated them to 32PSI all round. I saw on an army 110 that they had stickers indicating the tyre should be at 36PSI at the front and 60PSI at the rear. My mate was a somewhat deterred at running 60PSI as the tyre wall is starting to perish and has a couple of cracks around the walls so we settled on 32PSI. We’re running eight spoke steel modular’s (I think) with general grabber AT’s.
I would have thought at 32PSI we would have been ok but stones were getting wedged in between the rim and the tyre bead.

Inner tubes-
I was running tube less rims which have had the valve hole drilled out to increase the diameter of the hole to take the valve of the inner tube. I’m certain the problem is the valve is catching on the hole of the rim were (as suggested) the tube and tyre are moving around the wheel and tearing away. Also I think the tubes are too small for the size of tyre I’m running. Hence why I’m looking for an alternative solution to running tubes. It’s probably the case that the garage that I asked to do the conversion are doing a poor job for the conversion but there argument is that the wheels are not designed for running the inner tubes. I’m disappointed with the outcome but they are correct in what they are saying regardless.
Can anyone give me some more information regarding these bead lockers?  Interested in knowing what’s involved with them and were to get them from and of course ££££££££???

I think they look cool and look like they could will solve our problem.
