I think you will find the 275/35-19 to be best for speedometer accuracy. The car reads high already. The very slight increase in diameter will only reduce how much the speedo reads high. Check the TireRack site for information on the difference in diameters.

I think the speedo reads somewhere between 3 and 5 percent high. If the new tire is less than 3 percent larger in diameter than stock, your speedo accuracy will actually improve.
