I went to 215/45/17 Michelin Exalta PE2 non runflats on my 2009 JCW and if I knew they would makes a difference for better riding, handling and quiet cruising I would have changed from the Dunlops a very long time ago. These are summer tires and not all season but me living in Florida is not going to be a problem at all. I paid $834.96 installed and balanced and will get a $70.00 rebate back from Michelin. Not bad when you figure in the Fee for disposal, Florida tax, State of Florida Tire Fee the tires only actually cost me $656.00 after the rebate.
