the easier handling? that's logical. I've also read that it corects the speedo.
The 225/55 is just a tab larger than the stock 240/50 so it only corrects the speedo slightly. The 245/50 adjusts it a bit more.
If you really want to correct the speedo then you need to use TuneECU or Tuneboy to change the settings in the ECU.
