Don't worry about tires "breathing" enough. ObedB is correct about "the brown stuff". The only stuff I put on my tires is completely water soluble and simply lays on the surface till it rains hard. RE pressure washing. Be careful to keep wands a couple feet away. The high pressure can damage the sidewall. There is a picture showing that damage on my blog post. See you all in W. Springfield. PS in addition to checking your hand gauges, I am working on test fixture for checking your TPMS if you have a portable monitor. If you are thinking of this, I advise to mark the cap on each sensor with tire position so you do not need to re-set the tire position. Sorry but will be doing a pressure check on TPMS at about 80 psi so you will need to change your low pressure warning level. More info at my tire seminars.
