Tubeless tyre seperates from rim constantly

[mitaux8030]

A question for you tyre gurus.
My ride on lawnmower has a tubeless tyre that keeps on separating from the rim. I've checked the seat is clean, no splits and that the rim isn't bent and runs true and tried a variety of inflation pressures - over and under. Anything else to check for? Driving me nuts!

Is it the right size tyre for the rim?

You havent said if its the front or rear tyre that keeps coming off.
In one way you should be envied as for most, getting the tyre off the Rim is often not a job one looks forward to.

If the tyre is leaking, they can be prone to coming off so as a suggestion, how about putting a Tube in it and see how you go?

I'm with Gordon on that one. A slow leak can be harder to find than a proper flat tyre.

Thank you all, next time the (front, pivoting) tyre separates, I'll jam a tube in there and see if that improves things.

If the tyre has been coming off and driven on, the bead and wall will be weakened, the only solution is fit a tube.

As Rick says, that is a major problem which you cant see and as you try to turn, the forces exerted on the tyre simply rolls it off the rim.

Now, IF your really feeling energetic, you could A/, swap the front wheels over. This will mean the tyre in now turning OPPOSITE to what ir was and it MAY stop the problem.
The next time and energy wasting exercise is change the Tyes over from one Rim to the other. this will keep the Tyre turning in the same direction as before (do it on a car to even up wear when you have alignment problems.

Now there's a thought, is the wheel alignment OK because if not, it could be turning the wheel OUT so its skidding on a turn instead of roilling?
If its rolling the tyre off more times when you turn more one way than the other could be indicative of an alignment problem.

I am full of wondrous time and energy wasting ideas and love watching others swearing and sweating trying to use their Lawn mower (push or ride on) Brush Cutter or Chain saw that works perfectly until you start to use them.........
