It wont as long as you get the correct size tire because you are not changing the overall diameter, just the diameter of the wheel. I believe the correct size is 235/35-19.

to add to what pigliiit said...
within the 5-8% margin of error that every car on the road is in.

i have 19's with 235/35 and dont think my speedo is off, that should be the correct size tire for 19's to not change overall diamater as someone stated above...........
