these buggers (on the left of the pic) have been a pain since i got the car, the 'O'-rings were leaking and the tyres have had a slow puncture.

so seeing as the cars off the road, i took the wheels to get the tyres off them so i could replace the seals, well, the boy was a bit handy when breaking the bead off and ended up snapping the tyre valve.

 

so i went to a few motorbike shops and found that theyre a pain in the arse to get hold of, but i saw that they had a type using the 'standard' uk type like a rubber bung with a chrome valve (as seen right on pic)

so seeing as these are readily available i thought i would ream out the valve hole in the wheels to take this type of schraeder valve.

i cant see why not, any one had a simelar problem before?

found the dimensions i need to ream the diameter of the hole
