My odometer just hit the 30,000 mile mark and my original set of Bridgestone Potenza tires are already shot. :-/ The inner and outer portion of the tread on all 4 tires is much more worn than the center. Strange! I kept the tires inflated to 44 psi, yet they still seemed to wear unevenly. My guess is that the combination of the narrow rear track of the car combined with the grooves and the angled slope of Florida highways has a lot to do with the odd wear pattern. Perhaps the roads and highways in Japan are more flat and less rough than those in the U.S.. Anyhow, I was wondering if anyone has a list of all of the different brands of tires that are available?? I've been reading in a couple of threads that it is best to stick with the RE92 Bidgestones, but I have to admit that I'm not much of a fan of Bridgestone tires. Any ideas?
