Think I am going to get the tc wheels with 225 40 18 tires so the ride height is as close to the same as possible. How much will the gas mileage suffer? What are your guys/girls experience after you went with a bigger wheel? Thanks!

I went from 25 city 28 hwy, to 22-23 city 24-25 hwy . I try to hypermiles most of the time, and under 2 thousand rpm off a complete stop.

It really falls on how much the wheels weigh compared to the steelies. If they are lighter, then it will most likely improve your mileage.

Same weight air off balances with the size of the rims

I never saw an increase or decrease in mileage with 18s. They were within 1/2 pound of the stock weight.
