Hi Roger!;

This is starting to look real interesting to me. Great idea. I love
raw data. Even though you have only 29 random responses, I see the
differential is real great. Its the back wheels. Now, does anyone want
to start interpreting the data? I am looking at it and saying to myself
it looks like overloading (tire failures are consistent with where the
typical coach's weight is, most on the middle, somewhat less on the
rear, followed by the front). Your sample shows blow outs in tires that
are older, but not the classic 5+ years, a scary thought. It looks like
failures start at 3+ years. Any other guesses?

Really nice. Keep it up Roger! walter bright, 76GB.

Roger--
I would think that whether the tires have been rotated of have been in the same
position for their entire life could make a significant difference in the
location of the blowout?????
