Retrofit T8 Brakes - 345/320mm to 366/340mm

I believe wheel size changes may also be related to the indirect TPMS some of the supported cars have.  "they detect a low tire by comparing relative wheel speeds via the Anti-lock Brake System (ABS) wheel speed sensors. When a tire loses air, its diameter decreases slightly."  So its possible this is a value it uses in that calculation, so it can know how far away from the center of rotation the sensor is to calculate speeds.
