It looks good. Now forget I said that.

At 60k or so, they're starting to get tired. If it'* in the budget, 50k is the safest interval. Especially with gas prices what they are today.

By the time "it looks bad" it'* well past time for replacement. It'* done its job for a long time...time for it to retire.
