Had a chance to weigh the stock '22 Si rims and tires this past weekend (W/O the Summer tire package). Switched over to 17" Konig Hypergrams. The new setup weighed in at 43.9 Lb.'s when mounted on 235/50/17 Pirelli P-Zero's I recently purchased on sale from TR. Love it when I get to lower that much unsprung weight.

That’s a solid savings. I wonder how much just the wheel without a tire weighs

I was wondering the same thing myself. Wasn't willing to take the tire off the rim to get that info. I believe the 29Lb. estimate is in the neighborhood though.

That’s crazy, my Miata 15x10s are 13.5 lol

True, but these are/were the stock 2022 Si rims and tire combo that comes on the vehicle when new. The 15" X 10" rims you have are aftermarket. I purchased a set of 17" x 8" Konig Hypergrams and the rims alone are 16.33 Lb.'s:
