GOOD TIRES….As I was picking up some Chinese food for dinner last night, it occurred to me that my car is two years old and I’ve never put air in the tires. I suppose the dealer might have done it the last time I took the car in, but even that was over a year ago.

What’s the deal? Have tires really gotten that much better? Are nitrogen and oxygen molecules bigger than they used to be? Is it global warming?
