Adding a valve stem to alloy wheels

hi geocacher
interesting idea
some rims have reinforcement around the valve hole both steel and alloy
but the idea has merrit in respect to the fitment of tyre monitors
if the rim has extra strength built into it where the normal valve hole is then i would be very causous about drilling an extra hole as cracking could result

but if there isnt any reinforcement at the current valve hole then it may not create any problems to have the extra hole and in that case
i dont know if it is illegal to drill extra holes in a rim or whether it would void your insurance someone might know

i would put it exactly opposite the other valve to keep the balance in perspective that my thoughts on it if its legal to do so but its a curly one ?????
cheers

Hi Dave,

I've done this to all our steel wheels after seeing a customers vehicle with a second set of valves in it, I personally wouldn't risk wrecking a set of alloy's (keep them good for resale) instead buy a set of good steel wheels ie: ROH or similar & have them drilled by a competent fitter.

Definitely worth doing as it makes life so much easier when airing up & down as much as we do!

If you do it yourself you can say goodbye to your insurance as it's an illegal mod according to the ADRs. You can however find some places that'll do it for you. It then must be approved by an engineer.

You could also look at buying rims that can accommodate the Staun beadlocks that have 2 holes from the factory.

Either way it'll be a costly exercise.

Hi

What's wrong with fitting in tyre monitoring sensors ? I fitted a set to my GU ute and simply bought two extra sensors. One I fitted to the spare and the other is in the glovebox just in case I damage one on a tyre change. Every time I ajust tyre pressures , which is fairly regulary, I push the reset button and alls well. On a GU steel wheel the valve stem fits close to the rim.
The only downside is the diameter of the airway through the valve stem is slightly smaller. In the bush to reseat the bead I simply remove the valve and use a short airline from the airtank to the valve.
