100K the hard way

On Wednesday, October 22, 2008, Devoted Dan hit 100,000 miles! :o) Since January 3, 2004, he’s definitely done a terrific job earning his keep.  I’ve subjected him to eight track days, on and off road escapades, and the rigors of a daily commute in Southern California.

But has he really hit the 100,000-mile mark?  The car came equipped from the factory with Bridgestone Potenza RE92 tires with a size of P205/55R16.  Properly inflated, those tires require 830 revolutions to travel a mile.  Much of the car’s street miles, however, have been on Bridgestone Potenza S-03 Pole Position (P215/45R17), Bridgestone Potenza RE-01R (P225/45R17), and Bridgestone Potenza RE92 (P215/45R17) tires.

Here are the number of revolutions each of these tires must turn to travel a mile:

  • Bridgestone Potenza RE92 (P215/45R17) – 847, 2% inflation over stock
  • Bridgestone Potenza S-03 Pole Position (P215/45R17) – 847, same as above
  • Bridgestone Potenza RE-01R (P225/45R17) – 833,  0.36% inflation over stock

Multiplied over “100,000 miles,” one can figure out that Devoted Dan has probably only traveled ~98,000 miles.  For you automobile enthusiasts whose vehicles are no longer on the factory-supplied shoes, the same circumstance probably applies to you.

With “100,000” in the book, here’s to many more miles and more importantly, many more good times! :o)
