While measuring tire wear may give historically accurate information we
really want to get it right before the tire wears unevenly.
Consider doing what is recommended at:
http://www.fluke.com/fluke/uses/comunidad/fluke-news-plus/articlecategories/automotive/racetracktemp
Admittedly much of what the site touts is not relevant to street driving
but you can get the information you need to adjust tire pressures in real
time. And while a contact probe may be most accurate I use an infrared
pyrometer to tell me whether tire temps are increasing too much or not
enough, etc. etc.
