I've never seen such a bad place to site a tyre valve in my life, why not hunt down a rim enabling the valve to be sited drivers side of the rim not right next to the rear drive.
Yes, and if the tyre fitter uses a standard valve stem rather than a short stubby one, it can hit the drive belt as the wheel rotates. I know of one instance where this has resulted in the Schrader valve core parting company with the valve stem. Obviously this resulted in a rapid deflation and corresponding pirouetting all over the road. Somehow, both driver and car emerged from this incident unscathed but it could have been a very different story.
