Made some custom 9mm shell valve caps today, current alloy ones weigh 2g each and the finished 9mm shell weighs 6g.

Will 4g make any difference to the wheel balance. I'm running gold calipers so thought the polished brass would compliment.

I had some caps on my motorbike that indicate tyre pressures (red/green) and my tyre fitter recommended I remove them as when at speed they bend the valve and could result in it breaking and at high speed not something I would want. You could actually see that valve bending due to the weight.

I would say replace the rubber valve with a metal one, and then you will be fine.

And at high speed these could explode and throw your car off the road????? Hehe they look great but not sure about the weight.

Managed to make a version 2 today, weighing in just under 6 grams and about 3mm shorter. Factory caps are 3 grams, these weigh about 5.8 grams.

Pretty confident now that 2.8 grams and slightly longer is not going to implode my wheels and break my rubber valve stems.

But happy to be convinced otherwise :)
