The guy at the tire store talked me into 245 / 40 for fronts. You don't want to go any larger. There isn't even a fingers width between the top of the tire and the spring of the strut. Also, I feel the height of the 245 looks a little big on the front. I went 275 on the rear because anything larger really reduces the manufactures to choose from and the prices go astronomically higher. Add to it that the choices you are left with will probably only last 10K mi and it just didn't make sense to me. Money may not be an issue, so you might want to go 285+ rears and 245 front. The 275 is stretching across a 10" rim, which added to the 245 looking big. I would go 235 - better fit and better asthetics.
