The main problem with the Bridgestones that come on the Insight seems to be uneven wear (even if you keep them rotated). Two of the original tires on my 02 CVT have worn bald on the sides (though tread in the middle is pretty good). But the tires on the front are in really decent shape, so I'm considering a purchase of just two tires. I've always been told that's a mistake, but the light weight of the Insight makes me wonder if I might be able to stretch some more miles out of the two that are still okay. (I'm at 56,000 miles right now). Anybody have experience with this?
