I know it's just one example, and not representative, but there it is.

Even if the tire does wear unevenly, I think most tires are due for replacement long before they wear out. The compound hardens over time and wet weather traction goes way way down. I'd think that tires even 4yrs old have far less traction than new tires, at least this is what I've found.
Hopefully our tire expert can confirm or deny my theory, but I've tossed quite a few tires that are nowhere near the wear bars because they are just unsafe in the rain and I don't mean aquaplaning either.
This is kind of a balancing act as we are accepting slightly lower traction to increase mpg and save the environment and $$ but buying new tires more often costs both...
Its a multidimensional math problem for sure. Traction vs. mpg vs. monatary cost vs Enviro cost...
