Hi
Bit of a boring topic i guess but none the less i need some hell please.

I need To put some air in the tyres but the size of the valve does nkt seem to be shrader or presta.

Could be a TR15 valve which is bigger than a standard car tyre. I had these on my 1974 Land Rover steel wheels. The hole in the wheel is noticable bigger than standard. Think they use TR15 on tractors and the like too. As an example:

Christ that post I put up was awful. Doesn’t make any bloody sense.

It doesn’t seem to be as big as a Shrader valve. It’s very odd. I’ll have to do some investigation but thanks I’ll have a look at your link.
Cheers
