Tire age

This concept has been a tough one for me, but I am convinced that the money spent to replace old tires is WELL worth it. The only parts of our trucks that are actually touching the road are the tires. Old tires ride and handle like bricks after 4-5 years. The nice ride that new tires bring is worth it, not even considering all of the safety aspects.

I have the same issue with my other cars that don't get many miles per year. The timing belt should be replaced after 100,000 miles or 7 years. I am approaching 70,000 miles and 9 years, but I have to get that belt replaced for the health of the vehicle and its occupants. All rubber ages, deteriorates, and should be replaced regularly.

I never would have guessed, but this happened to me last summer.
Rear tires, probably about 20 years old, fronts were only 10 years old, with maybe 2000 miles on them. On the way to Goodguys in Spokane, started getting a pretty bad vibration and noise on the highway. The old truck has always had a bit of a shake.
The next morning leaving the hotel, the rear tire was flat, and missing sections of tread. We checked the other tires, and they were all starting to crack. Even the front, and the tread looks like new. Still had the hairs on the side. It was a long scary drive home. Much slower than the speed limit.
So all new tires this year. I am just glad it didn't blow apart on the interstate.

Sounds like the Co-op brand tire issue I mentioned earlier.
One tire blew. Then I inspected other 3 and saw small radial cracks near tread on sidewall. Not the typical sidewall dry rot cracks.

May not be a bad idea to check tires for belt separation cracks every fill up.
