20” to 18” factory rims

My 21 limited currently has factory 20” wheels on it from new. I found a good deal on fb marketplace for factory 18” rims with tire sensors still installed. Did not purchase yet.
Will my speedometer need re-calibrated changing rim size and will my tire psi monitoring system see the new sensors or will I need programming at the dealer or tire shop?

 

no issues with making that change. Installer will sync new sensors when you get rims installed. Swapping factory 20s for 18s could not be simpler.

 

Thanks

 

Yup, My sister just did this for a winter set of wheels.
Got them at Finishline Wheels. Pretty sure all the 18-20 inch OEM from 2007-2021 fit the same.
