My 2006 Charger has a set of Toyo Proxes on it which I installed when it was new. They've not been a bad tire, although kind of noisy and getting noisier. Now at 5 years and 30,000 miles later, I'm wondering if I should buy new tires. The tread is still good, but they're 5 years old. We use the Charger as a trip car, so it's loaded with stuff and Debbie is with me, so not a good time for a blowout. The cautious side of me says to buy new tires, the practical side says don't spend the money.
