I've been following this thread with much interest since it started. I also bumped up the tires on the protege to sidewall max, 44psi. All was well for a while...
I got married on the 8th, so made 4 120mile-round-trips to the airport that week. Well, 80+ empty and late twice, 80+ full and late twice, and always 65 and drafting on the way back. It was always 90F or above here in FLA.
The day of the wedding my now wife heard a weird noise, sounded almost like a siren. Maybe like airpressure through a valve stem?...
Gas mileage went way down (filled up on monday and WTF???). So today i checked and pressure was 0psi
according to my awsome chrome $3 guage.
Filled it back to 37, it was at 35 an hour later... I haven't found any punctures, but based on the weird noise report, i'd say this wasn't your everyday roofing nail or whatnot.
My gut says the valve stem couldn't hold a full car at 95F
and my wife driving
