Test drove the p85+ today... Really like the tesla a lot. Questions abound. How many miles should I expect on a set of tires? Do the fronts and backs wear equally? How is it in stop and go traffic with the creep/regenerative breaking (I commute to Manhattan daily). How much charge will I get at a supercharger in 20 mins.. I was already in the market to buy in this range.. Panamera vs Tesla p85+.... Any thoughts or advice?
