What really got me thinking about this was I was 100 miles from home, which ain't much, but we absolutely had to be back early Sunday. I was just gonna rent a car and send the wife, she could handle what was needed at home. Truck is a 2007, no TPMS, but it is a diesel, about 4300 on the front axle all the time. Truck is primarily for towing or hauling, just turned 73,000, so I did not think a ten year old spare would be unsafe. This will be my last serious truck, as I get closer to full retirement, we will be on the road more. Those cracks on the spare are I what I thot I would see on a sunbaked field find at 30 years, not a barely used spare.
