I think these are the original tires based on date codes of 07/18. Tread depth is still about 5/32 which is kind of amazing. We're making a couple of long trips this summer. Should I replace these now?
I wore out several sets or wranglers when I had pickups. Always rotated including the spare.
Ran them down to 3/32. Always liked to have fresh ones put on in late fall on the 4WD pickups. Even at 3,4 or 5/32 they worked pretty well on snow and perfect on dry paving. When I bought new ones, the dealer would automatically charge me for disposal. I’d tell him to take the charge off, I’d take the tires with me. That kept them out of his used tire rack. Then I’d take them to the city park that had a tire machine. I’d leave them stacked up by the door and tell the foreman that the seasonals could have them. The next day there would magically be no tires and a couple happy seasonal guys or ladies. Did that with my Honda Accord Michelins too.
I have bought and sold tires for 60 years. Never worried about a car or truck tire aging out if it was getting driven regularly. Obviously some don’t feel this is correct and others feel I’m right. Matters not to me, this is my experience.
Have a great day, rotate your tires, check the pressures often, keep them balanced, inspect them and pick out the rocks.
I changed two valve stems on fluid filled rear tractor tires earlier this month. The tires are 21 years old. Heard one ask the other if he wanted to roll into town and have a cold one now that the fat guy gave us new stems and some fresh air. They looked good with 14 lbs pressure in them.
