Flat tires and New Mexico? Interesting.
On our annual NM trip 2 years ago we had the rear passenger tire come apart--
complete delamination, chewing up the sheet metal behind it. This was on the
little twisty mountain road above White Sands and taught me the value of
driving while awake. Funny thing, the tire held air just fine in the
remaining layer of rubber (these were the Uniroyals that were heavily
recommended on the list a few years ago). Then, to cap things off, the dadgum
Vanagon drunken monkey jack broke clean in half.
Even funnier (ha ha) the next day the other rear tire did exactly the same
thing, but instead in heavy traffic at 70 on the highway.
We HAD gone through Roswell....
