Tire Wear

Getting ready for a 6-7k mile trip, the tires on the truck have 36k on them. They measure 8/32nds vs 15/32nds when new (the spare).

The old standby method is using a penny to show worn out tires at 2/32, and the newer call (TireRack) to change them at 4/32nds usesg a quarter instead of a penny. Using the more conservative 4/32 and my measurements I should be able to get about another 15k out of mine.

Think this pertains to TV tires as well as non TV? Or should I bite the bullet and replace them before we head to the national parks in Utah where I'm guessing tires can be harder to come by.
  • I don't know, at 8/32nds, you are nowhere near the end of the tires life. If you calculate you have 15k left, and you're only going to drive half that distance, it seems kind of silly to replace them now. And believe me, this comes from Mr. Preventive Maintenance. It would be a different story if you figured you would reach end of life some time around when you get back, but you will still have another 8-9k left!
  • I don't like starting out on a trip with components that are near end of life. Maybe I am just overly conservative, but for my own peace of mind, if I were in your shoes, I would put new tires on it before leaving town.
  • Just installed 6 new tires. Discount tire was cheaper than tire rack.
