Markus,

It wasnt a problem that I came across. Im not sure whether you are having trouble taking the tyre off the wheel hub, or the taking the wheel hub off the axle boss.

I used a split nylon wheel hub - very light and strong, and an aluminium axle boss that gripped the axle and was driven through a keyway. Everything fitted together and came apart easily.

For the new robot, using smaller wheels, I machined down the boss to fit, and drilled new holes in the split hub to fit the boss.

You can buy foam inserts for split rim hubs off the shelf at a good go-kart shop, they dont weigh to much either as they are ment for racing!

We use plumbing insulation, but you really have to push hard to get it in tight enough to pack out the tyre. You can rivet the tyre to the wheel hub I guess....

Does anyone know any good online go-kart tyre suppliers? I tried looking yesterday and apart from 300 links to Tornados site, I only found one - very expensive.

Why is it so important to fill kart tyres anyway? They are hardly ideal for robots - and the nice flat floors we have dont require the compliance of a pneumatic tyre.
We use the tread section of kart tyres, but cut off the sidewalls and bolt the treads straight onto our wheels - These cannot be punctured now! Better still, the fancy stuff Ed uses on his Storm 2 wheels.

Its all a matter of money. But vulcanising metal with Vulcalon or similar stuff is very good, if you can afford it.
