If you are getting custom wheels, a good wheel shop will be able to get your sensors in the new wheels. I have one set which are deep dish 3 piece and they drilled a hole on the inside center of the rim and installed the sensors there. So there are two valves in the wheel but you only use the one outfitted on the wheel to fill them.
