Just back in Fla from Maine. Had two Flats (different tires). Some thoughts:
(1) Flats on Mass Turnpike and I-95 respectively. Did not know we had problems until passing cars gave signals. If anything the Bambi (2001,19') tows too well!
(2) Used spare to get to tire places, bought new tires. Found, in second case, that tire stem had deteriorated (suspect that same problem occured in first case but cannot confirm). Tire place (Savannah Tire, Richmond Hill, GA) said that stems do go bad after 3-4 years. Also pointed out that stems come in a 3 flavors: regular, high pressure and metal. I put high pressure stems in all 3 tires.
Afterthoughts: Anyone have ideas about monitoring tire pressure while underway? Do people have upgraded tire stems installed? If your tires are 3-4 years old and your rig sits around more than it rolls you need to think about stems (one more thing to worry about).
Would like to hear from others with similar experiences.
