Metal stem
I plan on replacing my spare tire with a new one, and placing it on the right rear of my Class C, then using the old tire as the spare. The new tire will be going on the rear, and will be the outside ...

The front tires are a little less critical than the rears, largely for the reasons already stated above. I've decided to keep the twinned rear duals together, and I have BORG custom valves on those. Then, the other three wheels have everyday METAL valves. I rotate Spare to Left Front, Left Front to Right Front, Right Front to Spare. I could "rotate" the rears by swapping the Left and the Right PAIRS but I don't think I will. An M&S or All Season tread pattern might develop a sawtooth wear pattern, but I don't think ours (Bridgestone Duravis R250), with Highway/Rib tread pattern, will.
