Hi essaykay and welcome to the forum :!:
Yup, any tire other than the OEM Bridgestones are going to reduce MPG.
See the thread:

Otherfactors in the "mix" will be the circumference of the tire that will either increase or decrease the _apparent_ MPG. The distance traveled per revolution will be greater or less based on the distance _around_ the tire (circumference). The speedometer / odometer simply counts tire revolutions to calculate MPH / distance.
HTH!
