And by this, I mean keeping tires alive for more than a few years before the sidewalls crack open like some old man's change purse.

35k miles on the car, an '05 PT Convertible GT, now getting it's 3rd set of rubber. The original Goodyear's split open after 5 years, the replacement mid levels just started splitting. Monday it gets new tires (actually just the fronts, the rears are a year old and were acquired after a pothole at LAX took out 2 rims and 2 tires).

Hoping that now that I drive it more than .4 miles a day, I think it's up around 5 now, that just letting them get some exercise will help.
