I changed out my wheels yesterday to a new setup
Previous setup: OEM BBS Style 219s (rear 9.5 inch) with Michelin Pilot Sports & Michelin Pilot Super Sports (all are 265/40/18s).
Michelin Pilot Super Sports on 18x9.5
Michelin Pilot Sports on 18x9.5
New combination
Bridgestone Potenza R-11 on Forgeline GA1R 19x10
Bridgestone Potenza R-11 on Forgeline GA1R 19x11
Unfortunately I was not able to weigh the wheels only or the oem 219s in 18x8.5 I hope this information helps.
