I know we already turned the subject around & around, but may I point this out:
Aged tires (sold as new)
Sensationalism aside, it's still worth to point out that tires have a shelf (and road) life. The "date code" part is interesting.
As for the "where to install worn tires" debate, my dad and some tire places I've been suggest to put the less worn in the rear, quoting oversteer prevention. Another "tire" place (Canadian Tire, for what it's worth :roll: ) installed new tires in front of my gf's car even though I asked otherwise (she had a flat and replaced only a pair). They had the FWD/traction argument. *shrugs* Both sides are logical and have their merits. As long as you're aware of 'em all, choose the way that suits you.
Myself, if the wear difference is minimal (if I have a matched set), I'd stick the best tires on front. They'll eventually wear some more, and then I rotate, etc. Else, you grind the already worn tires even more, and need to replace those two. The rear tires then last for years, leading to the age problem.
To end the debate: buy 4 new tires (or a set of used, but matched and with equal wear), and rotate 'em frequently!
