Thread: getting 235/85 on to a Disco rim

rar110

I know what you mean. Ive had the same trouble. I've tried putting a ratchet strap around the centre of the tyre and tightening it up as I had heard that was supposed to work. Didn't work for me using an ARB compressor. I guess it must work sometimes but may depend on the flexibility of the tyre sidewalls etc. I did take the valve stem out to allow air in as fast as possible.

I have heard of people using a suitable size push bike tube and partially inflating it and putting it between the bead of the tyre and the rim to seal one side of the bead. I don't know exactly how it works but I assume it must be well lubricated (push bike tube that is) so that it doesn't get caught when or if the bead does seat. I've never got round to trying that method so maybe someone on the forum knows exactly how it is done and can give the rest of us some clues.

Cheers

Reasonable question guys. I've only ever seen tubeless tyres seated using high volume workshop air supplies. What about those Tyreplier kits, etc. - they must have some method of seating the bead after replacing the tyre? Or should you just carry a tube to use with your 'last resort' spare tyre?

The tyre-plier type of tools are only for getting the tyre bead off, and getting the tyre onto the rim. Unless you carry one of those new "air-up" bottles around, I think the only successful option would be to use a tube.

Soapy water can help form the seal,it would be worth going to a tyre dealer and buying a jar of the lubricant they use and puting it in your spares kit.
I belive they call the stuff Elephant Cum

thanks for the feedback. I will try the rachet strap idea tomorrow. I can't understand how the bike tube works. I don't want my fingers anywhere near the edge of the rim when the bead snaps tight on to the rim.

I have managed to inflate 3 out of 4 tyres. I used lots of soapy water and suspended the tyre on two sides and bounced on the rim to get it to seal on one side. Then I turned the wheel over, again suspended the tyre on two sides, and applied downward pressure to the rim to push the rim against the tyre. This hasn't worked on the last wheel.
