Susie is out fishing on a calm, sunny day. She hooks an old tire that is resting on the lake bottom, and hauls it into her boat. In principle, how does the water level of the lake change?

• Physics -

doesn't the weight of the tire displace in the boat its full weight? In the water, the tire sunk, so it was not displacing is full weight.

Therefore, it seems to me that the boat with the tire will displace more liquid going down, which means the lake rises...in theory.
