Just adding a note on valve stem failure. While I've yet to hear of anyone suffering tire failure from hyperinflation, one EcoModder member has suffered valve stem failure:

Quote:
I had two tires split at the valve stem. One actually started to leak so badly that I had to change the tire.

My max PSI is rated at 44PSI on the sidewall, and I was running 55 PSI, but on the day of the tire failure, I filled them to around 55 or so ........... and found out later how inaccurate that tire guages can be. I was actually at around 65- 70 + PSI.
( So it's a good idea to check the pressure with more than one guage. )
