Tube filling

What compound would be best to fill go kart tubes to make them solid?

Foam from old sofas, tornado used it

never bothered, just left air in mine, but use an innertube. Mighty Mouse had/has some sort of silicone rubber in his, but i seem to remember it being fairly heavy.

Meggamouse has a jelly used in tyres for cherry pickers as their tyres need to be puncture proof. The jelly can be removed and fitted to other tyres. The ones on Meggamouse were on Velocirippa and are nearly 10 years old now, the hubs have been replaced many times but the tyres have all sorts of holes and still behave like a fully pumped up air tyre.

Downside; they are 3kg each, the jelly is injected as a liquid and baked for 24hours so has to be done professionally and is not cheap. 10 years from a set of tyres is pretty good value for money though in my book..........

anything that can be done at home thats just better than having air?

all im really scared of is axes, just something to either stop them deflating or at least prolong it till after a fight

I use garden hose :mrgreen:

you can with those wheels, cant really try that on kart ones :)

Scar has some sort of Silicone gel in its tyres, by the looks of it its been done through the valve. Maybe its the same thing Trev was talking about as they do weigh an awful lot too. Maybe you could get a bathroom sealant type thing and try doing the same? Maybe on a wheel that doesnt matter first though.

try and old bike tube and some expanding foam?

Cant hurt to try, if you're not needing the bike tyre that is.

fill them with hot glue

tried looking and their is very little info out here on this

tempted to try and use house told silicon

@alan, do you leave the wheels just with air even in merlin?

Yup, just air. Builders foam doesnt' work, as it goes hard and just falls apart. You can get kart inner tubes off ebay.

Don't bother with expanding foam. If you leave the wheels with weight on them for any great length of time, you will create major flat spots on them.

For my last heavyweight, I got these guys to cut me some circles of foam (the RECONSTITUTED (Super firm) stuff)

I cut the center out of the circle and slotted it in between the hub and the tyre with a lot of swearing. The wheels were punctured several times by kan operner along with others but the wheels kept on rolling.

if i have the time, ill get on the phone to those people but i do have spare tubes so i should be ok for whitwick anyway
