The speedo is also spot on with the GPS on that tyre size although it goes against everything said on here and tyre size web sites. The tyre size calcs aren't much cop. My 215/35/18 also read bang on to the GPS. The trouble is the tyre calcs can't forecast the dynamics of a changing effective rolling radius. It's good to see a 40 profile will work. As I find the ride a little crashy on mine.
