We bought new tires for one of our vehicles yesterday.

I took a memory train back to the first time I bought new tires after I was married.

That would be 1975. The car was a 1968 Camaro. Sweet, small, fast car. RS, 327 V8, automatic. I bought it for $1100 after I arrived at my first permanent duty station in my Air Force career, Wright-Patterson Air Force Base, in Ohio. Paid cash.

I married later that year. My wife and I have wonderful memories of being together in that car.

Buying new tires for it was a major financial decision. Recaps were cheap, $20-$25 each, installed. But recaps? I distrusted their safety and reliability.

That meant new tires: $40 each.

$160.

Ouch.

We didn’t have credit cards, so we’d need to buy the tires with cash. I had that in savings but that would severely reduce the balance.

I remarked about this to my wife at dinner last night.

She remembered, adding, “Yes, the things we couldn’t afford then that we needed, and the things we buy now, that we really don’t need.”

I paid for the dinner with my credit card. Leaving, I thought, I could have bought two new tires for the price of that dinner.

Of course, I could have bought the Camaro for the price of the new tires I put on the car.

It’s all part of Einstein’s Theory of Relativity.
