I got less than 3,000 miles out of mine (my woes are posted here somewhere). Three went on the same trip home. A trip that should have been 5 hours was over 14 by the time we finally made it home. I'd say for your short trips on Florida, you may be okay. But for any other longer trip, and especially before Alaska, get new tires.

I thought I was wrong once, but I was wrong!
