A week after buying my 99 GTS, I lost a left rear on the D.C. capitol beltway at midnight after a day running in Va with the club. Not a lot of fun, rain, etc. I think I hit something, but always wondered if pressure was also a factor. I have gotten in the habit since to *always* do at least a visual on all 4, and bought a good pressure gauge and check rears almost every time out. The right tends to lose one PSI, and I like to make sure the rears are the same. Just like flying - *always* preflight. Your life rides on only *you* checking.
