Vanners,

Well, the left rear tire saga is over [3 gone in 3 months].

I pulled the tire and found a non repairable slit on the edge of the
tread/sidewall interface.

Found the serial number on the tire I pulled, it was on the inside tire
wall. Built in 99.

So it's new tires for me. Hankooks from a local dealer. $585 for 5, ouch.

If the left rear tire goes again you'll all know, and you won't need a
computer to hear the scream of agony.
