Wheels are still 19" with fronts being 19x8.75 +18, and rears at 19x11.25 +23.
Even with these wheels being wider than oem, there is still nearly 31 lbs in weight savings!
With these offsets, the wheels sit more flush to the fenders and give a wider stance.
I went with Michelin Pilot Super Sports in 245/35/19 - 295/35/19.
I checked with many wheel experts, and the consensus was these were the best sized tires for these wheels. I will add pics to the original post to better show offsets.
