I know there will be some who will be dead set against such sacrilege. For the record, I am just considering it and have not made a decision. I have a 348 with 355 wheels. They have a deal running on Michelins right now which gets me 4 Pilot SS wheels mounted and balanced for under $1000. My biggest worry is that they put it on the lift at the correct points. The manager said they could do it and would take all the risk of doing something incorrectly.
