The owners manual actually lists the OEM tires. Michelin MXV4 are probably the highest recommended by dealers & indys for hours of long, smooth cruising. They are $$$ and many have tried alternatives, i.e. Bridgestone Turanza LS-H, Continential, Kumho, ... My biggest complaint with the Michelin's once they wear down some (WAY above the wear bars) they don't handle well in wet weather. A big trade off.
