I have had the ZE512 for one summer so far, last summer, they have plenty of tread on them. I think they will last for 3 summers for sure. They are loud when they are rolling but at 74 bucks a piece for a half decent tire. They are not a summer only but I wouldn't use them in the winter. They dropped to 44 bucks a peice from 48 at tire rack, the guys you see in magazines. I haven't tried them at an AutoX but they are not realy for that. Next time I think I would go to the 55 or 50 series. The 60 seiries looks really big. The 50/55 are also softer, but that means going to a wider tire or going to a larger diameter. I just put them on my stock 15s. I like them. Sorry for not having this in any kind of order.
