Thanks, Tika and Jim.
Tika, yeah, it's mildly annoying but not much, I just top them off every morning when I'm out on the road.? I'm not really concerned about the slow leak, it takes a few days for it to lose half its pressure.? What I'm more concerned about is that one of them might blow when I'm 1000 miles away and out in the middle of nowhere, just because they are 32 years old and it's their time.
Is there a time beyond which these things should be replaced just because?
