My '02 just recently passed 34,000 mi with the OEM Potenza's. At my most recent fill-up, I ran my finger along the treadline of the closest tire and found there's still plenty.

I had been told they were only expected to make it 30,000 mi, and their life would be drastically shortened if you use Toyota's recommended 34 psi. So, I've been running them all at about 41 psi for most of the 34,000 mi.

Either I got a really good batch of tires, or else it confirms that tire pressure in the low-40s is ideal for tire longevity in addition to mileage.
