I am more north in the county in Phoenixville but I also plan to get new tires soon and am planing to get 19"
Michelin Pilot Sport A/S 3+ as well. Not sure of the impact of them on range though. Most people seem to go with the Primacy MXM4 if they go Michelin I guess because they are OEM but other than that not sure why exactly. As far as places to get them installed, I have had luck in that past with CJ Tires but I am sure it depends on the specific location. The one by me has really competitive prices and have been less than tirerack. When I asked for price quote for the Pilot Sport A/S 3+, the final installed price was less than tirerack before shipping (and without install). If you purchase from tirerack or somewhere else and just need them installed, my friend owns Diverse Autoworks here in Phoenixville. I know his guys will take care of your baby.
