Yup, you won't get pressure warning issues changing tyre diameter as long as you reset it once the new tyres are fitted.

you'll end up with tyre pressure warnings or traction control errors if altering the rear only, there'll be a diameter mismatch, and a rotation count error over several miles. Only my2p.
That should not happen if you do the initialising procedure after fitting. You're supposed to do it every time you re-set the tyre pressures anyway.

I'll echo that Locoblade - I've got TPMS on my E46 2.5ti and its tolerant as long as you reset it after new tyres fitment

Yeh, I went from standard sizes to 225/40 Front, 235/40 Rear, then every winter to 225/40 all round winter tyres and never had an issue.
