ive got a 66' splitty and it needs new tyres but the ones on it have tubes. Im pretty sure the hole where the valve goes through is to big for a standard size valve any ideas can you buy valves with bigger diameters.

Maybe someone has some info on the fitting of tubeless tyres on non-safety groove rims. I had quite a problem when I wanted tubless tyres on the notch as the tyre fitter said it was illegal for him to fit them. The old style rims are supposed to have tubes in them.

"Don't tell anyone who fitted them" I was told!!!!

I never knew that. So there's different types of rims? I know it's possible to get a tubeless tyre fitted with a tube. Not much help though.

Let's see. There's nothing really wrong with running a tubeless tyre while using a tube to my knowledge. My mother's car was fitted out that way by the tyre store because of the roads she had to drive on.

If a tubed tyre is properly fitted there shouldn't be any problems like hotspots. They can last as long as their tubeless counterparts.

The only other option I can see is get a set of splitty rims and get the centres fitted to something else.

Hi,

I am running 165/15 tubeless tyres on my '63 single cab on standard rims. It's fine. So far I have not done any rough work with it though I have done a few extended trips and will be running it from Canberra to Lismore later this month.

are you using special size tyre valves ? Good too know.

The larger tubeless valves are available from good tyre shops.

If you look at our old VW rims they haven't got the small groove at the outside lips. Later "safety" rims have a groove on each side to help prevent the tyre coming off the rim (towards centre) should it lose air. Maybe also to help keep tyre on rim whilst "hooning" with a fully inflated tyre!!

I had an argument with a tyre fitter about this once, although it was with my bike. He said I could run tubeless tyre's on my rims (alloy), and some PPL had with no problems, but when I asked around my bike friends, they said you can do it but the problem is there is no safety hump on the rim and under hard cornering the bead can suddenly seperate from the rim causing "instant deflation" on a bike cornering this means your on your ass pronto. I wouldn't like to be driving your splitty when something like that happens. If your using standard rims with no safety hump, fit tubes. for the sake of $50, it could save your life.
