The new Auris (2015) accepts 2 sets of TPMS, so the main set does not get overwritten. It doesn't matter in what order they will be written to the ECU - just need to be written and the car manages them, so no re-learning necessary when rotating tyres. The only thing one needs to do after switching summer and winter sets is to press the TPMS initialization button in the glove box 3 times and that's it!
