I have a 540i coming in a couple weeks and will probably fit winter wheels/tires to it. I already have 18x8 ET30 Rial wheels from F30 that should work, but will need new tires. Couple questions...

1. Current wheels have 433mhz sensors...are these compatible with G30?

2. My preferred tire is a non-run flat for ride quality and perceived better resistance to pothole damage. Currently using Pirelli Winter Sottozero 3 non-runflat 225/40-18 on F30 but only available in run-flat 245/45-18 for G30. Other non-runflat option is Blizzak LM001, or runflat Michelin Pilot Alpin or runflat Dunlop Wintersport 3D. Any others I should consider or just go with the Pirelli Winter Sottozero 3 in runflat?

thanks.
