Help With Dual Rear Wheel Valve Stem Access

[Gizmo1137]

So we just picked up our Vita 24P on the Mercedes chassis and as I was familiarizing myself with it, I noticed the valve stems on the rear wheels are impossible to access but I can barely see them. Part of the problem is the tiny holes in the wheels, so much so it took forever to unscrew the vale stem cover on the front wheels. Another problem on one dual rear wheel is the tiny holes on the outer wheel do not line up with those on the rear, so impossible to insert a tire gauge or air pressure chuck in straight.

The immediate obvious solution is to install extensions, but having been told by the tire business who replaced tires on a dually I use to own that because of hazard, safety and air leak issues he refused to install them. While it makes me nervous, if this is the only viable solution I would consider it.

Any suggestions, I would appreciate and gratefully received.
