I've never heard of the 711's I thought it was a typo in your post. Anyways 10k miles and several burnouts and trips to the track and parking lot autocrossing and my 712's dont show much wear at all. I expect to get between 20 and 30k miles out of them easily. On the other hand they suck for your 60ft at the track. But you dont go there so I'd say there a good all around warm weather (wet/dry) tire. And you cant beat them for the price.
