I just upgraded to the 3IS F-Sport wheels from the base 17" non-F wheels. Would I need to bring my vehicle in for calibration for accurate reading or would it not matter?

Try this : https://tiresize.com/calculator/
and compare the tire size. I think below 3% is acceptable (not sure)!

Thanks for your help! It looks like my speedo should be fine, but I might take it in for odometer reading.

If your speedometer is good then your odometer should too. I mean if your speed is off by 1% for example... your odometer too will be off by 1%.

I wouldn't worry about it too much if I were you. What's the percentage you got from the calculation?

First image is rear tires, perfect. Second image is the front, but it shouldn't matter because the difference is so small and I hope it reads mileage from the rear because RWD.

The Lexus cars do not have the ability to calibrate the ODO.
