They are not Z rated. I think they are S or something. Anyway, I have them on the CRV and they are awesome. One of my favourite tires. REALLY good in rain, nice handling and ride. Price and selection are good too, although they are not cheap. I would take them over SPA2s in a sec. I have had a few DOZEN A2s. I even consider the TRZ for performance apps like my RSX. I went with the Kumho ASX instead. I like the ASX, but they are soft sidewall and in fact, quite a lot like the A2. Still, I would take the TRZ over many others. Wear has been great. I would consider them for the RSX as I said, just for wear, but I really want Conti Extremes again for the winter performance. Yokohama makes a great tire. I have H4S on right now, great handling, very crisp. Not real good in snow. Similar to the G-009s but I think G-009 has the edge with a typically good Bridgestone ride PLUS the handling. Any of those tires are great, but I'd say from best handling to best ride...

In snow, ContiExtreme and A2s are very good, ASX are good too. fwiw, there is a TRZ thread with a lot of posts, all favourable.
