Default 33 tire help

So Im pretty set that im going to go with 33x12.5s now when I plan on doing my BL or possibbly a superlift from some guy I know. However, Ive heard that with the 33s it will cause my speedo to be off a couple mph is this true? and how can i fix that? Second will my mpg change? I average about 15-16 in town and I have an auto with 4.10 gears. And last has anyone noticed anything in the way it handles: change in cornering/ harder to turn the steering wheel? and slower off the line? If you guys notice anything else on your ride please let me know i just wanna clear things up before i get em. Oh and post some pics as well and im plannin to go with a 15x8 wheel of course

yes your speedo will be off, can be fixed with a tuner or an expensive speedo calibrator that superlift sells. ive also heard some dealerships can calibrate your speedo too but im unsure about that. yes it will affect your mileage switching to a larger tire, more rolling resistance, more weight and it raises your final drive ratio which in turn will also slow you down acceleration wise. most of that can be remedied with a gearing change. handling will be different mainly because of the lift required to fit the tires unless you go with only a body lift. the tires alone wont change your handling much at all with the exception of braking. larger diameter tires require more braking force to stop. that can be fixed with upgraded performance pads/ rotors.
